OIL VS. GAS – Which fuel is safer?

While a leak in your oil tank may cause temporary inconveniences, there have been no deaths or injuries associated with leaking oil tanks. The risks of injury are far greater with natural gas leaks and the statistics from the U.S. Department of Transportation’s Office of Pipeline Safety show that between 1986-1998, natural gas pipeline accidents have resulted in the deaths of over 200 people, injured more than 1,700 people, and caused more than $300 million in property damage. So safety is a legitimate concern.

Is natural gas cleaner and more efficient?

This is a misperception that is refuted by studies done by the U.S. Environmental Protection Agency, and the U.S. Dept. of Energy. According to these studies, heating oil and natural gas produce approximately the same levels of pollutants. Natural gas is not cleaner than heating oil. According to the U.S. Dept. of Energy and the Gas Appliances Manufactures Association, heating oil equipment is actually more efficient, on average, than natural gas heating equipment.

Is either natural gas or oil better for the environment?

No. Both fuel sources cause similar amounts of pollutants in the environment. Many environmentalists are concerned about the risks to our wetlands, river and forests, that will be the impact of gas pipeline construction, and about leaks and accidents that have occurred in existing pipelines. Further, many have expressed concern about natural gas as it is a power greenhouse gas which contributes to global warming.  If you are interested in heating with a fuel that is environmentally friendly, ask us about our biodiesel home heating oil.

Buying a Home Heated With Oil? Get the Facts!

Portland, Oregon – For many people, buying a new home is among life’s most stressful events. It ranks high with getting married and welcoming a new baby into the family. The process can become more complicated when the house being considered for purchase is heated with oil.  After months of active searching, Kimberly and Alex Gorham1 found a home in Southwest Portland that met their desired criteria with a single exception—the house was heated with oil.  “Neither of us had ever lived in a home that had oil heat,” explained Kimberly. “We both had negative associations with heating oil tanks and assumed that the underground tank on the property would have to be decommissioned. It was a foregone conclusion that we’d convert to natural gas.”

Addressing Common Misperceptions

According to Rhonda Lehr, it is not uncommon for homeowners to be confused about heating oil. Misperceptions abound, from “It’s illegal to put a heating oil tank back in the ground” to “They don’t make oil furnaces anymore” or “Heating oil is dirty.” Lehr knows because she’s a customer service manager for the Oregon Oil Heat help desk, a phone line that the Oregon Petroleum Association administers to address the needs and concerns of heating oil customers as well as the industry as a whole. The help desk is a place for heating oil customers, real estate agents and potential home buyers to get answers to questions ranging from where to get equipment to how to find a reputable soil tester.

When it comes to helping potential new home buyers decide whether to keep a heating oil system or convert to another source of energy, however, Lehr doesn’t get nearly as many calls as she would like. “By the time homeowners have made a real estate decision, they’ve already been convinced that they need to convert away from heating oil,” notes Lehr. What many people don’t know is that the most practical, economical and environmental solution for many homeowners is to stick with heating oil. Indeed, the Consumer Energy Council of America Research Foundation concluded that in 95% of all cases, it makes economic sense for a homeowner to stick with heating oil. After 18 years of taking customer service calls, Lehr understands why homeowners who choose to stay with heating oil do so, including:

  • Competitive prices. Small independent heating oil dealers compete with one another to keep prices as low as possible. Customers are free to choose the dealer that best meets their needs.
  • Peace of mind. A heating oil storage tank on one’s own property provides a level of security, control and price protection that other home heating options can’t offer.
  • Heating oil is a very safe fuel; it is a liquid so it cannot explode. It also has an extraordinarily low risk for carbon monoxide poisoning.
  • According to the Environmental Protection Agency (EPA), modern oil burners are one of the cleanest combustion sources available, releasing near zero levels of smoke. Moreover, a good working heating oil system doesn’t release any odor or soot into a living space.
  • Heating oil provides even, ambient warmth and burns very hot, thus warming your home quickly and completely.
  • Personal relationships. Many heating oil dealers are multi‐generational, family‐owned businesses whose employees are committed to providing the best customer service possible.

The Tank Issue

None of this is to say that heating oil tanks are not an issue. “Anyone buying or selling a home that has an old heating oil tank in the ground needs to inform him or herself of the tank’s condition,” says Greg Brennan, an equipment specialist who trains heating oil technicians at Portland Community College. Brennan is also co‐owner of Universal Applicators, a tank and environmental services company that works throughout the Pacific Northwest.   “The reality is that older heating oil tanks can leak,” observes Brennan. “Nonetheless, many homeowners choose to continue using oil heat even after a cleanup is completed because they prefer it over other energy sources.” Fortunately, the oil heat industry has been working for decades to design tanks that withstand the most severe conditions. Replacements for older storage tanks range from aboveground tanks that are designed to fit into small basements and garages, to underground tanks made of ultra‐strong, corrosion‐resistant fiberglass and steel.   So what do you need to know if you are buying a home with a heating oil tank? According to the Oregon Department of Environmental Quality (DEQ), homeowners/sellers who know of any tanks on the property that are no longer in use must ensure that the tank has been emptied of oil and must give the buyer documentation that it has been emptied. (Note: This is not the same thing as a tank that has been “decommissioned,” a generic term for taking a tank out of service by cleaning it, then removing it or filling it in place with an inert material. If a homeowner stops using an underground tank, DEQ only requires that it be emptied. Decommissioning is entirely voluntary.)

If a seller or realtor can’t tell you whether there is an oil tank on the property, Universal Applicators’ Brennan suggests looking for visual clues, such as a vent pipe (usually attached to the side of the house) or a fill pipe (normally located in the ground, near the house). He also recommends looking on the basement floor or walls for concrete patches where oil lines once were. In the absence of visual clues, he tells homeowners to check with the Department of Environmental Quality (DEQ) for any reported releases or hire a qualified expert to check for a tank on the property.

Once a tank is discovered, the next step is soil sampling. According to Oregon state law, soil samples or tank tests are only required when an underground tank is suspected of leaking, or if oil is known to have leaked into the ground. Nevertheless, soil sampling is now a routine request during property transactions. Anyone borrowing money to purchase a home is likely to be required by their lender to conduct soil testing to determine whether there has been any contamination on the property.

When it comes to hiring a contractor to conduct soil sampling, home buyers and sellers are encouraged to do their homework. Many companies that do soil samples also make money on the cleanup, and there have been isolated cases of fraud. (For example, some companies have been caught selling a cut‐rate, single‐sample service in which they collect the two samples required but send only the most obviously impacted sample to the lab for analysis. The seller is then presented with a bid for the cleanup, without the benefit of full representative information.) The Oregon Oil Heat help desk can provide homeowners with a list of tank testers that have demonstrated good business practices, and consumers are encouraged to check with consumer ratings agencies such as the Better Business Bureau and Angie’s List. Of course, any time a homeowner is concerned about the integrity of a heating oil tank, he or she should have it checked or have it emptied and replaced. It is always in the best interest of both buyers and sellers to be sure that a tank is sound, and a replacement tank is much less expensive than allowing a known or suspected problem to continue.

The Lowdown on Leaks

So what to do if an underground tank is found to leak? Brennan’s first advice to homeowners is “don’t panic.” That’s because a tank leak is not the environmental catastrophe that most people believe it to be. The days of soil clean ups running tens of thousands of dollars and entailing huge excavation projects are gone, in large part because environmental experts recognize that heating oil in soil usually has a limited impact to humans or animals. In addition, DEQ’s requirements for soil clean ups have been modified so many projects require very little soil removal. Instead, a series of soil samples can be taken that document the contamination, and verifies there is no threat to ground water. This information is compiled and submitted to DEQ who then will close the file on the site. Leaking tanks are also not the financially devastating accidents that they are purported to be. In Oregon, the average clean‐up cost from a leaking tank is under $4,000. As Lehr from the Oregon Oil Heat help desk points out, tank service contracts offered by oil heat dealers cover much of the cost of the tank replacement and cleanup.

“If a homeowner has an old tank that is in good working condition, with no evidence of oil ever having leaked out or water having leaked in, it can be covered for up to $4,000 for operational or structural failure with a tank replacement,” explains Lehr. “There is a phase‐in period over a year, and an automatic delivery schedule to monitor usage is required for coverage. That’s because when customers order 100 gallons here and 100 gallons there, nobody is proactively monitoring for oil loss. Full-service programs keep tanks full via an automatic delivery schedule and are better able to detect a problem early.” Greg Brennan at Universal Applicators admits that the idea of having an old tank in the ground is unsettling to some people. “But as with anything, regular and proper maintenance is the key to keeping an oil heat system running safely and efficiently.” In fact, when it came to building his own 3,000 square foot home, Brennan chose oil heat for its superior efficiency. “A heating oil tank is like the roof on a house—with proper installation and ongoing care and maintenance, its lifespan can be extended for many, many years.”

Making an Informed Decision

For new homeowners Kimberly and Alex, sticking with heating oil was a logical choice. The house they had purchased had a brand new, high‐efficiency oil furnace. The underground tank was not leaking, yet there was plenty of available space if they decided to install an aboveground tank in the future. They also liked the idea of controlling their own heating supply, and being able to balance out the highs and lows of oil prices without being tied to a large public utility. Last but not least, they had their hearts set on an oil‐fired hot water heater, which provides unlimited supplies of hot water at a fraction of the cost of a gas or electric water heater.

Still, Kimberly and Alex needed additional assurance. “As consumers who just want to do the right thing in terms of cost and comfort, we needed additional data points.” With input from friends, colleagues and their home inspector, they learned that conversion is an extremely expensive, long‐term investment. In some cases, the thousands of dollars it costs to convert to natural gas are never recovered once you consider the costs to remove the old system, run the gas line, prepare the new gas system, do the plumbing and wiring and buy the equipment that will only last about 15 years (heating oil equipment, in contrast, lasts up to 30 years). Moreover, people who’ve spent the time, money and effort to make the switch often complain that they are simply not as warm and comfortable as they had been with heating oil.

The Bioheat Benefit

Lastly, for Kimberly and Alex, there is also the issue of the environment.  “oil has a huge environmental benefit—especially as biofuels become a better option.”   Indeed, many homeowners who once considered converting to natural gas are opting to stay with their oil heat systems as biodiesel heating oil becomes more readily available throughout the country. “Biodiesel heating oil is a well‐tested and renewable fuel made from vegetable oils like soy and canola grown domestically,” explains Tyson Keever, Co‐Founder of SeQuential Biofuels. “When used for heating, biodiesel is mixed with regular heating oil to produce a new energy source that has the highest BTU content of any alternative fuel and is extraordinarily clean‐burning.”

In Oregon, the most common blends of biodiesel heating oil are B20 (20% soy or canola oil mixed with 80% regular heating oil) and B5 (5% soy or canola mixed with 95% regular heating oil. And while 5% may not seem like a lot, if everyone using heating oil used a B5 blend, more than 400 million gallons of regular heating oil could be conserved. For homeowners like Kimberly and Alex, that’s a major selling point.

Another selling point is that homeowners don’t have to make any modifications to their existing heating oil systems to begin using blends of B5 or B20. In fact, biodiesel naturally cleanses and lubricates a heating system, potentially lowering cleaning costs and extending the life of equipment that has been properly cared for. “For homeowners who keep up with regular system maintenance, there are no problems using low blends of bioheat,” assures Keever. (To use higher biodiesel blends, up to and including B99, homeowners will need to make certain modifications to their heating oil system, depending on the materials in their tanks, pumps and fuel lines.) “Most people don’t associate heating oil with alternative energy,” concludes John Huber, President of the National Oilheat Research Alliance which focuses on consumer and professional education, as well as research and development in the oilheat industry. “Yet home heating oil has reduced its carbon footprint by nearly 40% over the last three decades. Thirty years ago, the average oil heat consumer used 1,300 gallons of oil per year. Today, that number has been reduced by nearly 500 gallons thanks to new technology and high‐efficiency equipment. Homeowners owe it to themselves to get the facts for themselves before making the decision to convert.”

Emergency Backup Generator’s – Why The Fuel Quality Matters.

                             Emergency Back Up Generator Diesel Fuel Quality

The fuel in your generator is the single most overlooked item in maintaining a back up generator.  Be prepared and know your back up generator diesel fuel quality is ready with these best practices.

When the power goes out, don’t let a decade old tank of diesel be your weak link.

 

Diesel Generator Fueling Service

As a provider of back up generator fueling services we know how critical fuel is in an emergency.

Back up generators are everywhere when you start looking for them.  Rarely needed but when a storm or disaster strikes their failure to fire will be extremely conspicuous. In the Pacific Northwest where resilience planning around a major subduction zone earthquake is a monthly subject of talk.  Back up diesel will be the only immediately power source after a quake.  Diesel generators are taking center stage for emergency preparedness, placing those who maintain them in some high level policy discussions.

Avoid a double emergency when the back up power isn’t there for your need by focusing on the diesel fuel quality.

The worst case scenario for fuel quality is water getting into your diesel fuel reservoir as well as biological growth occurring in that water logged diesel. If water is present in diesel, and that diesel is in a warm dark place, bacteria will start growing in your tank. So first preventive step is watch for water.  The most likely problem with fuel you will see is the fuel aging and degrading in place over years of not being used.  That can be addressed with your routine maintenance on the tank.

CIM-TEK water absorber

NOTE: To get a small amount of water or to ensure a dryer tank of fuel, CIM TEK makes a Tank Dryer which absorbs a small amount of water in a tank. Handy similar to adding a desiccant into a closet with a slight condensation issue. 

Back up power generator diesel fuel quality.

The big rule for storing back up generator fuel is to make sure the diesel you use is clean and dry.

First ensure you are testing the generator by running it once a month.  Move fuel through the system and ensure the generator is starting right up. Run the generator for a while to use up fuel and be prepared to order a regular top off when you get below 3/4th of a tank. When checking the fluids on the generator prior to start up see if the fuel filter has a visual transparent bottom where you can see what the fuel looks like there. If it looks like dirty fuel or there is evidence of water take notice.  After cycling the generator take a peek and make sure the fuel it’s pulling into the generator is bright (not dark and degraded).  If you are seeing any water (even a small drop) that is an indication of real concerns.

If you are using up half a tank a year and adding to it, the fuel quality will usually stay within specification.  If you have worries the easiest way is to just start over. With older generators sometimes it’s a good idea to just evacuate the tank (empty all the older diesel fuel) and replace it with fresh diesel treated and stabilized for long term storage.

Most back up generators are seeing routine annual maintenance where the mechanical needs of the equipment are walked through. If this is occurring ask for a bottom sample from the back up generators fuel tank. Also ask to see what the fuel in the bottom of the fuel filter (assuming they are changing that) would give an indication if problems might exist deep in the fuel tank.

Back Up Diesel Generator Fuel Service

Sampling and Onsite Testing of Fuel from Generator Diesel Tank:

  1. Pull sample from tank bottom
    1. Use a professional “Bacon-Bomb Sampler” (google it to see one) or a small fuel transfer pump available at any auto parts store.
  2. Visually inspect it by swirling it in a beaker or mason jar.
    • Look for water and dirt fall out as you swirl.  If you see a few drops of water form you’ve got a water problem. If you are seeing coffee ground type material in the fuel, that’s biological growth. If an algal or gunk type slime appears, that’s also biological growth.
    • If clear like cranberry juice and bright – your fuel is in good shape.  If a darker cherry color yet still clear, your fuel is aging and you should consider swapping or burning fuel off in the next year.
  3. If fuel is dark in color (showing that it is aging in the tank) you can send that sample to a lab to test it. You want to ensure you are confirming the following:
    • Oxidation Stability (or Accelerated Stability)
    • Water Content in PPM (under 50 PPM is what you want, under 100 PPM is not uncommon, and over 100 PPM there is probably water in the fuel and you want to pursue remedial action.)
    • Make sure the fuel testing lab you are using (your current fuel vendor should have a recommendation or do it for free for you) is checking for:
      • oxidative stability (if it’s aging out of specification),
      • biological growth (if bugs are growing in it),
      • water content (indicating a puddle someplace in the tank causing higher water content in the fuel) and,
      • dirt content of the fuel (if there is dirt, there is probably biological growth or some other problem).
  4. Set aside sample in a warm dark place for a month and check it for biological growth occurring which will confirm if you have fuel growing inside the tank.
    • How to test diesel for biological growth In-House:
      • Take your sample that appears to be in great condition and set it aside in a warm dark place for a month (day light kills most biological growth in fuel, though day light ages your diesel in other ways).
      • When you come back to look at the sample, if a film or layer of darker color is appearing in the fuel, this is biological growth occurring.
      • If you see nothing and want to experiment further, add a slight amount of water to this sample, shake it up, and put it back in a warm dark place.
      • When you check back if there is a a new layer of darker color on the surface of where the water contacts the fuel, that’s what grows in your tank.
      • If nothing grows, your fuel is safely stabilized for storage this year. Even if water is finding its way into your fuel tank, the fuel is safe and will be ready to start.
        • NOTE: Do not leave water in your tank, even if the fuel looks good. Eventually it will be a major problem and something will grow. If you are putting biocide in your tank regularly and their is an environment for growth, something resistant to that biocide will take root and you WILL NOT be able to get it out of the tank without serious effort.

NOTE: If you are curious to see a fuel lab analysis of the diesel this is an example.  This is a lab analysis from Hydrotex, Star Oilco’s premium diesel additive provider.  They are very supportive in testing everything we send them for quality assurance.

In most cases, it’s water and dirt in the fuel leading to further degradation over time. If gone unchecked it will lead to mechanical failures in your fleet.

 

Donaldson Filter has a great educational video about the high stakes importance of aggressive filtering of your diesel prior to going into your fleet. Today aggressive filtering and ongoing quality assurance of your fuel is a must. Star Oilco calls this Precision Fuel Management and we offer it to all of our bulk fuel customers.

Precision Fuel Management is the ongoing improvement of your diesel fuel quality.

This is done by adding aggressive Donaldson filtration to the dispenser on your diesel tank or filtering fuel on Star Oilco’s Mobile Onsite trucks when wet hosing our customers). For bulk storage tanks, we include a Donaldson desiccant breather to the vent on your tank to scrub moisture from the air as it is pulled into your tank, as well as Hydrotex PowerKleen Premium Diesel Additive. In addition to these best practices Star Oilco will also sample your tank bottom, as well as take a representative sample out of your diesel nozzle and lab test this fuel according to the ULSD ASTM standard D975, as well as check for the ISO cleanliness level of your fuel. We test twice a year going into Summer and Winter to confirm if there is water on the bottom of your tank as well as any worries about dirt, biological growth, or any other recurring, but preventable fuel quality problems.

NOTE: ASTM D975 is the specification for ultra low sulfur diesel in the United States. ISO Cleanliness is a standard to check for microscopic dirt that can harm the performance of your engine systems long term if it’s getting past your engine filtration. 

https://staroilco.net/bulk-fuel/biofuels/precision-fuel-management/

Diesel technology has advanced a long way in the last decade to meet the extremely high emission standards of the EPA and CARB for diesel engines. What this advanced diesel tech means is that your engine has extremely high-operating fuel pressures and extremely tight tolerances for the fuel acceptable to the long term use of your engine.

What does this mean in a nutshell?

High operating fuel pressures and tight tolerances in the fuel rail mean dirt and water can destroy injectors and affect the operation of your fleet. These two contaminants (dirt and water) are the source of most other fuel-related problems and therefore your highest exposure to preventable maintenance cost. If you have experienced unexplained fuel filter spinning, failed injectors, and DPF maintenance that is more than normal, it may be fixable with Precision Fuel Management.

Precision Fuel Management is aggressive filtration at the fuel dispenser combined with PowerKleen Premium Diesel and a clean dry tank bottom that is sampled and tested regularly. If you want to look into cleaning up your bulk fuel, give Star Oil a call. Our first step is a complementary test of your fuel.

If you have an immediate concern about biological growth and long-term storage with your diesel, we recommend an alternative stopgap measure. Treat your fuel with Bioguard Plus 6 to kill the bugs growing in your diesel fuel.

Low CO2 Diesel Fuel – B99/R99 Facts. 1024 683 Star Oilco

Low CO2 Diesel Fuel – B99/R99 Facts.

B99 and R99 Biofuels are the alternatives to petroleum diesel in Oregon

Oregon bans the sale of petroleum diesel, a rapid transition to biofuels such as renewable diesel and biodiesel are happening.

 

Oregon HB3305 explained

 

 

HB 3305 Petroleum Diesel ban

In Oregon, HB3305 is a House Bill proposed by Representative Karin Power outlaws the sales of petroleum diesel to the public for use in motor vehicles.  HB3305 quoted below:

“Prohibits retail dealer, nonretail dealer or wholesale dealer from selling petroleum diesel for use in motor vehicle on or after specified dates. Requires public improvement contract to require that motor vehicles be powered by fuel other than petroleum diesel. Prohibits public body from using petroleum diesel in motor vehicle under control of public body”

The full text of the current version of HB3305 can be seen here.

HB 3305 mandates non-petroleum diesel be the only legal fuel for sale to diesel powered motor vehicles in Oregon.

Star Oilco has customers ask about this proposal and how real it is?  In Oregon the focus on low CO2 fuels in the legislature is so consistent we can expect this to not go away.  Even if HB 3305 does not move this Legislative session, this will not be the last of biofuel mandates.  For this reason Star Oilco has been working to be ahead of the curve with non-petroleum diesel substitutes. Star Oilco has been selling B99 biodiesel since 2002 and renewable diesel since 2015.  If your fleet has an interest in learning more about low CO2 fuels or try these fuels, Star Oilco is ready to serve you with both R99 renewable diesel and B99 biodiesel.

News coverage of Oregon HB 3305 is below

The Center Square’s Oregon, whose coverage of this has been syndicated to many other online news organizations, lead with the headline: Bill in the Oregon Legislature would ban diesel fuel sales by end of decade.

CDL Life had this to say: The bill would begin to ban the sale of “petroleum” diesel by “non-retail dealers” as soon as 2024 in Clackamas, Washington or Multnomah counties and state-wide by 2027.

Landline as well has following the story: Oregon bill would ban petroleum diesel. Later in the article they add this to the background of HB 3305’s origin: Power said in a statement that her goal is to phase out petroleum-based diesel and replace it with renewable diesel. She says she introduced the bill on behalf of Titan Freight, a local trucking company she says has already transitioned to renewable diesel.

KXL covered this local news quoting Oregon State Representative Shelly Boshart-Davis, a legislator who owns a trucking company and actually buys quite a bit of petroleum diesel.

Lars Larson radio interviews Rep. Shelly Boshart-Davis about HB 3305.

KQEN news radio in Douglas County also covered it with the headline: GOP says supermajority declares war on working class.

The Wildcoast Compass covered the story quoting Rep.Vikki Breese-Iverson (R-Prineville): “There is absolutely no way we can implement this legislation in accordance to these timelines without extreme disruption to Oregonians’ daily lives and the obliteration of our economy as we know it,” 

Oregon Public Broadcasting covered HB 3305 a few days after the bill dropped which might be an indication it’s moving forward. From the story: One bill, House Bill 3305, would set a staggered timeline for ending sales of diesel in the state — first in the Portland area, then throughout Oregon. Its backers hope to spur widespread use of “renewable diesel,” a product with far lower emissions that can be used in any diesel engine. They say the fuel could be an important and near-instant way for the state to cut into greenhouse gas emissions while other technologies emerge.

The Banks Post covered HB 3305 as well with the headline: Diesel fuel under fire in Oregon legislature.

What HB 3305 means in the real world?

HB 3305 means the petroleum diesel used by any commercial vehicles operated on Oregon’s highways will be replaced with biofuels.

Biofuels will replace on-road petroleum diesel at all Oregon:

  • Retail gas stations
  • Trucks stops
  • Commercial cardlocks (Pacific Pride and CFN)
  • Privately owned bulk tanks
  • Mobile on-site fueling (wet hose fueling), and
  • All other bulk deliveries of diesel fuel. Star Oilco wanted to provide more background of what this law would mean for Oregon.  We hope this provides in depth information about what the options are for diesel fuels and a whole host of background information.  The news coverage so far fails to really provide this depth and background for those with concerns.  If you have questions, please do not hesitate to ask. Star Oilco seeks to be a neutral and accurate source of information.

Star Oilco sells renewable diesel in bulk and by our mobile on-site fueling service. It is worth mentioning from our first hand experience that users of it become raving fans.  Renewable diesel is a new fuel that many believe out performs petroleum diesel in every way. Many customers who have used it experienced improvements in horse power, fuel economy, and emission regeneration system performance.

Currently renewable diesel is in extreme high demand, limited production, and commands a high premium over petroleum diesel with few sources of supply.  Renewable diesel has some major backers in the trucking industry as well as OEMs.  As the availability of this next generation fuel grows, the number of plants manufacturing it expands, and it’s price comes down, this type of law may make far more sense.

If petroleum diesel is no longer legal for sale in Oregon, what does that mean diesel vehicles will use?

There are two immediately available diesel rated biofuels that can replace petroleum diesel.  These are two very different fuels. Renewable Diesel and Biodiesel have differences in their properties.  So please don’t confuse biodiesel and renewable diesel as the same fuels.

Biodiesel and Renewable Diesel are very different fuels.

Biodiesel is a proven and longtime available fuel in Oregon.   Biodiesel is not actually a hydrocarbon diesel though, it is a diesel like biofuel made from vegetable oil usually sold in a 5% to 20% blend with petroleum diesel. It is not recommended to run pure biodiesel in late model diesel engines if they have a particulate trap.  This differs from Renewable Diesel which is a next generation synthetic hydrocarbon diesel made from various feedstocks including vegetable oil.  It is actually diesel, it can be used as a pure drop in fuel without any blending with petroleum diesel.

What are non-petroleum diesel fuels?

Oregon HB 3305

Biodiesel or B99 (99% Biodiesel + 1% Petroleum Diesel)

Renewable Diesel or R99 (99% Renewable Diesel + 1% Petroleum Diesel)

Blends of Biodiesel and Renewable Diesel (branded REG UltraClean Diesel)

HB3305 allows for biofuels in replacement for diesel.  We assume that change would be from a current Oregon fuel mandates of B5 or R5 biofuel diesel blend to a B99 or R99 mandated fuel.  Oregon’s biofuel content law can be read at ORS 646.922 and we can assume this would change that to a 99% mandate. Why 99% instead of 100%, that is a good question relating to Federal regulation of the US diesel and gasoline markets.

 

Why does this require a 99% blend (B99/R99) instead of 100% biofuel?

The reason biodiesel and renewable diesel are sold at a 99% blend is because of Federal rules associated with how petroleum companies must handle these fuels.  For this fuel to be used under the US EPA’s Renewable Fuel Standard program biodiesel and renewable diesel must be blended at a minimum 1%.  When fuel is blended at 1% with diesel, the EPA enables it to generate a “Renewable Identification Number” or “RIN” which is regulated to ensure a minimum amount of biofuels is used in the stream of commerce for fuel in the United States.  This Federal program is separate and unrelated to any program in Oregon, though the law recognizes and seeks to align with the framework created by the EPA.

What are the fuels HB 3305 allows to be used by diesel motor vehicles?

The two fuels immediately available if are B99 Biodiesel and R99 Renewable Diesel.

Both of these fuels exist today but have their own drawbacks.  In a nutshell, B99 is not a drop in substitute for petroleum diesel.  It is recommended to be blended at 20% with petroleum diesel (NOTE: B99 biodiesel can be used in modern diesel with an up-fit kit provided by Optimus Technologies).  On the upside, biodiesel is plentiful and competitive with petroleum diesel in cost.  If HB 3305 passed though this plentiful fuel wouldn’t be a ready substitute beyond a 20% blend with renewable diesel or with mechanical changes to existing trucks.  Contrast this with  R99 renewable diesel as a drop in ready to go substitute for petroleum diesel.  It is ready to use without blending, but has the downside of being in short supply and at a cost premium above petroleum diesel.

If Oregon’s over 2,000,000 gallons of diesel usage a day (or 750+ million gallons a year) was mandated to renewable diesel no doubt that premium would probably exceed $2 a gallon over petroleum diesel given R99’s lack of ready additional supply.  This $5 a gallon presumes that Oregon would have to pay more for the existing renewable diesel supply finding it’s way to California with several dollars a gallon of value paid for it’s lower CO2 baseline value.  California has a Clean Fuel Standard and a CO2 Cap and Trade program which provide a monetary value for renewable diesel’s lower CO2 numbers.  Oregon has a Clean Fuel Program as well, but it’s program does not pay as much for low CO2 fuels as California, making low CO2 fuels such as renewable diesel more expensive in Oregon.

B99 Biodiesel in depth.

Blends of biodiesel below 20% are extremely common in Oregon.  All fuel must contain at least 5% biodiesel content and many retail outlets, cardlocks, and major truck stops commonly sell a 10% to 20% blend of biodiesel around the state.

Biodiesel is a diesel like fuel manufactured by a chemical reaction called transesterfication, typically from vegetable oil or recycled cooking oil.  It is made by a relatively simple process and biodiesel has been a proven fuel in use in Oregon for nearly twenty years.  Star Oilco started handling and selling biodiesel in 2002.  Prior to 2007, B99 was commonly used by many commercial fleets due to it’s huge reductions in tail pipe emissions.  Vehicles manufactured after 2007, are clean diesels.  The US EPA required new clean diesel emissions systems which are impressive in their ability to make modern diesel engines extremely clean, but they can only handle biodiesel blends below B20 or 20% biodiesel unless an upgraded system is added.

Today B99 is a possible fuel for a modern clean diesel fleet with an upgrade to existing vehicle fuel supply system.  Optimus Technologies has an approved technology to enable a modern diesel aftertreatment system to operate without problems on B99.   Star Oilco has purchased five of these systems and is currently fielding them in the Pacific NW.  We expect these systems to be mainstream in coming years, but just like Renewable Diesel the technology is newly available and scaling up.

If you are interested in using biodiesel in your fleet, you can contact Star Oilco with questions or if you want to start researching we highly recommend starting with this US Department of Energy handbook titled Biodiesel Use and Handling.

 

R99 Renewable Diesel in depth.

Renewable Diesel is a next generation biofuel made from fats, oils, and greases. It is not an alternative diesel, renewable diesel is a petroleum free hydrocarbon diesel fuel. It is diesel! Renewable diesel not only less than half the CO2 of diesel refined from petroleum fuel, but it is cleaner burning and has shown evidence of reducing the cost of maintenance in fleets using it. Renewable diesel is a profound technology which has the potential to use the lowest grade trap greases, sewer materials, rendering wastes, municipal garbage, and a host of other refuse products making them into this high performance, sustainable, low CO2 diesel.

There are two categories of technology that renewable diesel is made from.  Hydrogenation and Fischer Tropsch process.

Renewable Diesel from Hydrogenation or Hydrotreating

Hydrogenation derived renewable diesel is very similar in manufacture to modern petroleum diesel in that the molecules of a the feedstock is cracked and reformed in the presence of a catalyst to form a very specific series of hydrocarbon molecules.  These being diesel and propane range fuels. The feedstocks used by renewable diesel plants are vegetable oils and animal fats.

The hydrotreating plants providing renewable diesel to Oregon currently are Neste from a plant in Indonesia, Diamond Green (in a joint venture with Valero), Sinclair, and Renewable Energy Group. All of these plants are over subscribed and 100% of their production is being taken at a premium primarily by the California low CO2 fuels market.   There are several new renewable diesel plants under way though.  Holly Frontier, Marathon, CVR Energy, and Phillips 66 are converting existing petroleum refineries into renewable diesel plants.  This process costs billions of dollars, will take years to complete, and also will be likely destined for California’s low CO2 fuel market with smaller markets like Oregon being an afterthought.

Renewable Diesel from Fischer Tropsch process.

Currently there are a number of smaller demonstration facilities making renewable diesel from wood waste and other feedstocks.  The largest proposed project currently on the books is Illinois Clean Fuels which will be collocated with major CO2 capture facility making their product negative CO2.  Fischer Tropsch renewable diesel is expected to be the future of refining given it’s flexibility of feedstock.  It’s process enables the use of municipal garbage, agricultural waste, woody biomass, and other low value plentiful materials as feedstock.  Given that the United States is called by some the “Saudi Arabia of garbage” we have plenty of supply waiting for a higher and better use as low CO2 transportation fuel.  Illinois Clean Fuels has a great explanation of how Fischer Tropsch makes renewable diesel and jet fuels.

Where can you get Renewable Diesel in Oregon?

Star Oilco currently is selling R99 Renewable Diesel for commercial use.  We can deliver to fleets seeking it in bulk or mobile onsite delivery (wet hose R99 diesel service began in the Spring of 2021).  Call Star Oilco if you have an interest in Renewable Diesel for your fleet 503-283-1256.

If you have questions about renewable diesel, Star Oilco wants to provide answers.  Feel free to reach out if we do not have the answer we will research it.

Diesel Soap: Identification And Negative Impact. 1024 768 Star Oilco

Diesel Soap: Identification And Negative Impact.

Star Oilco answers: What are Diesel Soaps?

Cliff Burbrink, chemical technology specialist at Cummins Filtration, provides a layman’s definition of diesel soaps:

“Diesel soap is not very different chemically than the soap used to wash your hands. The main ingredient in a bar of soap is formed when lye reacts with fats or oils. Lye is sodium hydroxide.

Fats and oils contain fatty acids. When they react, they form sodium soaps. Diesel soaps are formed from acidic additives in the fuel [such as some corrosion inhibitors and lubricity improvers] reacting with trace amounts of sodium.”

 

Rick Chapman, Industry & OEM Liaison Manager, Innospec Fuel Specialties, adds that acids can be derived also from other sources:

“[Soaps] can also be formed from free fatty acids in biodiesel starting materials and carboxylic acids derived from oxidatively degraded fuel and/or biodiesel.”

 

From a layman’s point of view, then, the formation of diesel soaps is the result of metals, such as sodium, calcium and potassium (in the form of positively charged ions, or cations), reacting with various sources of acid in the fuel.

 

“When these two species [acidic compounds and cations (usually sodium)] come together, diesel soap can form,” says Chapman.

“There are a lot of other factors or variables that can play into it, of course, such as pH, solubility, mixing intensity and so forth—but this is the basis for it. Unfortunately, when these soaps form, assuming they are formed from additives, they make the corrosion inhibitor or lubricity improver inert, and the corrosion or lubricity protection provided by the additive is lost.”

 

 

 Diesel soaps

 

  1. Plug fuel filters
  2. Form injector deposits that lead to over-fueling
  3. Create Turbocharger problems
  4. Generate Oil dilution
  5. Cause Poor performance, and poor fuel economy

 

In a May 2013 report, “Case Study—Impact of Poor Diesel Fuel Quality on an Urban Fleet,” Cummins Filtration investigated problems with diesel engines in a New York City bus fleet.

Complaints ranged from an excessive number of turbocharger fault codes to smoke at start-up to fuel-injector failures. The investigation uncovered excessive soot deposits in the turbocharger, resulting from over-fueling, which was determined to be the result of fuel injectors sticking because of deposits that were “rich” in the metals of sodium and calcium.

Although injectors showed sign of scuffing—the result of hard particle contamination, which, says the report,

“is the greatest fuel quality concern for high-pressure/common-rail fuel systems, worldwide”

—investigators determined that scuffing was not the primary issue for the immediate problems the bus engines were exhibiting.

The culprits in this instance were “metal carboxylates” in the fuel, more commonly know as “diesel soaps.” The recommended fix for the problem was use of a fuel additive that could both clean the Injectors and minimize further deposits, coupled with much tighter filtration.

 

Another Bad Actor

 

 

 

Biofuel is manufactured by reacting a plant-derived fat or oil (usually soybeans in the United States) with an alcohol, using sodium hydroxide as a catalyst. An unwanted by-product of the process is glycerin.

Although most of the glycerin is washed out during the manufacturing process, regulations do allow 200 ppm to remain.

Biofuel usually is mixed with petroleum diesel in 5-, 10- or 20-percent concentrations to form biofuel blends, but even at these relatively low concentrations, enough glycerin remains to create filter-plugging problems when, under certain fuel moisture and temperatures conditions, it becomes a solid and drops out of solution.

To help counteract glycerin’s effects, Jim Peterson, sales manager for Donaldson’s Hydraulics and Clean Solutions Group, suggests these measures:

  • Filter fuel on the dispensing side of the bulk tank and use proper on-machine filters
  • Keep fuel dry with proper tank flushing and proper breathers
  • If possible, moderate the temperature of stored fuel above the glycerin dropout level
  • Turn over fuel as quickly as possible
  • Keep fuel infrastructure as free from particulate contamination as possible
  • Ask OEMs about using detergent additives to keep glycerin in solution, both in equipment and bulk storage

 

Filtration and Additives

 

 

 

As noted before, the contamination of diesel fuel with soaps is not as prevalent, at least in many fleets, as other sources of fuel contamination.

These other fuel contaminates include hard particulates, increased water in biofuel blends, rapid oxidation of such blends, microbial growth, so-called asphaltenes (compounds that can agglomerate into an oily sludge), acetic acid formation and glycerin.

Glycerin being an unwanted by-product of biofuel manufacturing. “There are so many inherent problems with diesel fuel today,” says Hydrotex’s Cummins, “that machine owners must take a holistic approach when attempting to resolve them.”

The best defense against diesel soaps (and for most other contaminants, as well) seems to be the use of premium filtration, like the “Donaldson clean & Dry kit which includes 4 micron particulate and water filters. The kit also incorporates a desiccant breather to absorb moisture.”

Donaldson Clean and Dry Filter kit

In addition, (tank intake, tank dispensing, and on-machine), good tank housekeeping, and a well-chosen additive package.

Additives might be included in “premium” diesel fuel offered by some jobbers, but solving a serious soap problem might require consultation with an additive supplier who can take a comprehensive, laboratory-assisted view of all the fuel-quality issues in a particular fleet.

But, the best efforts are no guarantee of complete success when dealing with diesel soaps.

“We’ve seen soap deposits form in engines that use our most effective filters—those proved to remove 99.9 percent of material 4 microns and larger and significant amounts of material smaller than 4 microns,”  says Cummins Filtration’s Burbrink.

“If soap particles don’t agglomerate before the filter, they can pass through it. When they hit the injectors, the heat can cause these particles to deposit on metal.”

 

Deposit control

 

 

 

“We have seen great success with some additives,” says Burbrink. “The use of good detergents has dropped the failure rate significantly in some applications. Unfortunately, we also have seen customers having issues even though they are using detergents.”

That said, a well-formulated additive package seems to be an integral part of the potential resolution of problems with diesel soaps.

A good, multi-functional package will contain corrosion inhibitors and lubricity improvers (some formulations use nonacid, non-reacting lubricity improvers), as well as a deposit-control agent that will assist in cleaning injectors and minimizing further deposits.

 

The Key

 

 

 

“The key to diminishing field issues is the use of a two-prong strategy,” says Innospec’s Chapman. “One, use an additive that provides the required lubricity but is resistant to reaction with metal hydroxides, and, two, use a deposit-control additive to ‘clean up’ and ‘keep clean’ any deposits that may form, regardless of the their source. Deposit-control additives are useful for reducing injector deposits, reducing filter plugging, and for carrying through trace amounts of water. In lower-dose rates, or at a ‘keep-clean’ level, they will put a protective coating on metal surfaces and not allow deposits to form—or will limit their formation.”

Hydrotex’s Cummins makes the point, too, that treatment rates for additives, a corrosion inhibitor, for example, might have to be adjusted to meet the conditions of a particular storage tank. Cummins also reminds machine owners that deposit-control additives might need time to work in certain situations: “Soap deposits can get very deep into the injectors, become sticky, and cause poor actuation of the pintle. A good additive package will help clean the injectors, but given the nature of the deposits, it’s usually not a quick fix. The process might require four or five tanks of treated fuel before improvement is noticed.”

Sunrock’s Dennis offers this suggestion to fellow fleet managers: “I would recommend that fleet managers, if they haven’t already done so, educate their fuel suppliers on the subject of upstream fuel-contamination issues and their effects on diesel engines.

Managers can use that opportunity to register their concerns about diesel soaps—for the purpose of promoting a partnership in utilizing countermeasures against diesel-fuel contamination. Their fleet reliability depends on it.”

What is biodiesel? Is it the same as raw vegetable oil?

Biodiesel is a cleaner burning diesel fuel made from vegetable oil. Simply stated, a biodiesel molecule is a                                                              vegetable oil molecule with the glycerol removed. Chemically, biodiesel is defined as a mono-alkyl ester of                                                           vegetable oil.

Biodiesel is NOT the same as raw vegetable oil or straight vegetable oil (SVO). Diesel engines actually can                                                             operate on straight vegetable oil (SVO) as a fuel. In fact, Rudolf Diesel’s first compression ignition (Diesel)                                                            engine introduced in 1895 used peanut oil as its fuel. Modern diesel equipment, however, requires some                                                          modification to burn straight vegetable oil, and it is yet unclear the effects of straight vegetable oil on diesel                                                         engine performance and longevity.

Will biodiesel void my engine warranty?

According to the National Renewable Energy Laboratory, “Original Engine Manufactures (OEM) provide a material and workmanship warranty on their products. Such warranties do not cover damage caused by external conditions, such as fuel. Thus, if an engine using biodiesel experiences a failure unrelated to the biodiesel use, it MUST be covered by the OEM’s warranty. Federal law prohibits the voiding of a warranty just because biodiesel was used – it has to be the cause of the failure. If an engine experiences a failure caused by biodiesel (or any other external condition, such as bad diesel fuel), it will not be covered by the OEM’s warranty.”

Star Oilco distributes only commercially produced biodiesel that meets ASTM D6751-03 specification – a demanding fuel testing regimen that guarantees the fuel will perform properly in your engine.

Biodiesel is considered an additive in blends less than 6% (B5). Petroleum diesel with 5% biodiesel added still meets ASTM specifications for #2 petroleum diesel fuel. The National Renewable Energy Laboratory and numerous states and federal fleets, including all branches of the U.S. Military, have performed more than 40 million miles of road testing on B20. The results of which have only been positive.

Fleets such as Yellowstone National Park and the City of Berkeley (CA) Solid Waste Management Division have had great success running diesel vehicles on pur biodiesel (B100).

Does biodiesel cost more than petroleum diesel?

Yes. The current retail price for on road B99 is $3.29 per gallon. Our customers pay a premium for biodiesel to support domestic energy sources and because of environmental concerns. Many biodiesel users experience a lower maintenance cost when they use biodiesel.

Can I use Oregon produced biodiesel?

Yes! In fact, the biodiesel you purchase through Star Oilco is produced right here in Oregon! Sequential Biofuels opened their first plant in Salem, OR in July 2005. This plant will produce 1 million gallons of biodiesel annually from waste vegetable oil. Oil sources include the Salem Kettle Chips plant. Country singer Willie Nelson is an investor in the effort.

Does biodiesel provide similar miles per gallon, torque, and horsepower?

In terms of energy contained in the fuel, a gallon of biodiesel contains slightly less energy than a gallon of petroleum diesel. For example, B20 tends to reduce fuel economy by approximately 1%. B20 users rarely report changes in torque or power. With B100, torque, power and fuel economy can be reduced by approximately 8%. However, the increased lubricity of biodiesel may help to counteract this energy difference. Some drivers report better performance with biodiesel, but most do not notice any difference.

Can I switch back and forth between diesel and biodiesel?

Yes! Biodiesel is the ultimate flexible fuel, so you can switch back and forth between biodiesel and petroleum diesel whenever necessary. Also, you can blend biodiesel with petroleum diesel in any percentage.

Is biodiesel safe to handle?

Yes! Biodiesel is ten times less toxic than table salt and biodegrades faster than sugar. The EPA has tested biodiesel’s health effects extensively and has classified it as a non-toxic substance that poses absolutely no threat to human health. Biodiesel is such a clean fuel that it is used to remediate petroleum spills in water.

Can I use biodiesel in an oil furnace (to heat my home)?

Yes! Biodiesel can be used in any diesel application. Oil #2 is the primary heating oil sold in the U.S. It is essentially the same as the diesel sold at gas stations, but contains much more of the pollutant sulfur. Sulfur contributes to acid rain formation, as well as the creation of nitrous oxides and particulate matter, both of which have serious air quality and human health impacts.

Biodiesel is just as warm as regular heating oil, but will help keep both the furnace and the air cleaner. It reduces the oily smell of the liquid fuel and makes the exhaust coming from the chimney smell better – a little like French fries. Pure biodiesel is biodegradable, and it is far less toxic than diesel. With a higher flash point, it is also less of a fire hazard. Biodiesel reduces emissions of cancer-causing compounds by up to 50%, and emissions of nitrogen oxides, particulate matter and hydrocarbons by approximately 20%.

Do I have to modify my furnace to use biodiesel?

No. B20 requires no modification to your heating system. However, biodiesel is a solvent, and will actually clean heating oil tanks and all fuel-wetted parts of a furnace. Because of this, users may experience clogging of the furnace fuel filter early on. Fuel filters are cheap and easy to replace, and the problem will end once the system is cleaned out.

If your heating oil tank is outside and/or underground,Star Oilco will only deliver B20 home heating oil. If your heating oil tank is located inside and above ground, Star Oilco will deliver B20 or B99.

Can biodiesel replace petroleum diesel?

For most of the 20th century, petroleum diesel has been consumed as though it would last forever. Experts disagree about how much petroleum is left and how long it will last. They do agree, however, that less new oil will be found and that prices will increase. Because biodiesel is “home-grown”, it provides energy security. Biodiesel can be produced on a yearly cycle, instead of a 10-million-year-cycle. While we can not displace all petroleum with renewable fuels, it is one important piece of reducing our dependence on foreign oil.

Treating And Refilling Your Diesel Backup Tanks 1024 768 Star Oilco

Treating And Refilling Your Diesel Backup Tanks

Here’s good advice if you are relying on diesel as a back up fuel in the Pacific NW.

Now is the time to refill and treat your back up fuel tanks.

Diesel as a back up fuel

Quite a bit of our business at Star Oilco is fueling back-up generators, emergency water pumps, refrigerated trailers and other long term off-road diesel storage requirements. In the Pacific Northwest, biodiesel blending is required by state laws and you need to take an extra duty of care when storing diesel as a back-up fuel.

This means that most off-road diesels and heating oils are ultra low sulfur diesel containing a small quantity of biodiesel.  That means long term storage requires a proactive approach.  You can’t just hope and wait to see what the fuel begins to look after years of storage.

Technical advice from Government Fleet Magazine to help you with storing diesel fuel.

Here is an article from Government Fleet Magazine on the subject which runs through the specifics of long term storage and what causes fuel to degrade when stored.  Government Fleet Magazine – How to Maintain Stored Diesel Fuel.

Star Oilco has also worked up a PDF check list on how to verify if your fuel is in need of freshening or is still in emergency ready shape.  If you are a customer of ours, we will deliver a laminated card version to keep next to your back up generator. If you are not a customer (or outside of our service area) drop us a message below and we will gladly email you the PDF.

For our customers, we recommend that you check the tank bottom fuel quality on an annual basis to make sure the product looks good. If the tank has sat for years and is dark in color (good diesel is bright and transparent – you will notice if it is in bad shape), we recommend pumping the tank out at least partially and replacing with fresh fuel. Often you can also hugely improve the quality of the fuel by polishing the fuel. Polishing is when you circulate fuel from the bottom of the tank through a pump, filter repeatedly in order to remove any sediment or growth from the fuel, and then place this fuel back in the same tank.

Look at your fuel for a bright and clear color.

For stored fuel, you also want to make sure it is stabilized and contains a biocide. Stabilizers prevent the oxidation of the fuel and prevent the effect of metals like lead, copper and zinc, which can react and degrade fuel. For heating oil systems with a return line, for instance, the fuel is flowing through a copper line to the furnace and then back to the tank in a return line.

Use additives designed to prolong the life of your emergency diesel fuel.

Biocides prevent the growth of biological activity in the tank. In scenarios whcontaminated_dieselere micro-organisms like algae, bacteria, yeasts, and other bugs are growing in your fuel, biocides can kill this growth. It is still important to remove the residual grit and other contaminants that are the hallmark of bugs growing in your tank. Usually you remove them by filtration or total turn over of the fuel. If your tank absolutely has to be clean, you can contract a tank professional to enter the tank and physically clean the tank bottom or reline the tank with either fiberglass or an epoxy resin.

Water in diesel destroys fuel quality rapidly. Check your tank for water every fall and spring.

In events where water finds its way into your storage tank, that can also be corrected by pumping the tank bottom. Additionally, you want to put in an absorbent material designed to absorb water and not fuel. If your long term storage tank has water and you are not planning to burn 100% of the fuel in the near future, DO NOT add anything that removes water by distributing into the fuel. Adding a “fuel drier” that actually pushes the water into solution with the diesel will worsen the long term quality of your fuel, not improve it. That water is where bugs find their home to grow in fuel.

Star Oilco will test your fuel at no charge if you have an open account.

Feel free to call us with any questions you may have about long term storage of diesel. Star Oil can also deliver treated diesel ready for long term storage complete with Hydrotex PowerKleen Premium Diesel additive to improve the long term storage quality of your fuel. For biocide, we use Valvtect BioGuard fuel microbiocide to kill any possible biological activity and prevent any chance of it starting.

Fuel Market News

Gas prices dipped slightly, and diesel prices saw significant price jumps this past week. Rack averages in Portland were down $0.03/gal while diesel prices were up over $0.10/gal on B5, B20, and R99. Renewable diesel prices dipped significantly this month, with prices as low as $2.50/gal. The Portland market’s need for Renewable Diesel will continue to be high in demand as the 2026 RFS deadline approaches, with diesel blends increasing to B50 blends. Questions of supply remain unclear, with Neste pulling out of the market in early 2025. Much remains unknown about the future supply of diesel in Oregon. Demand will be very high, and supply will need to be strong to support this. Where the supply comes from remains unknown for most. The winter blend of gas and diesel will soon be back on the market as we roll into September next week. This may create an initial increase in prices, with pricing dips following into October/November. Oil prices have remained slightly below $65/barrel. OPEC+ has announced a production boost headed into September, which may lead to crude oil prices below $60/barrel into the fall/winter. 

fuel-market-report-star-oilco-5-18-24

Important Note: Per the City Of Portland, “Distributors in the City of Portland are required to meet the minimum biofuel content requirements for all fuel they distribute beginning on May 15, 2024. All diesel fuel distributed to retail stations, non-retail dealers, or wholesale purchaser-consumers must include a minimum of 15% biofuel content, from either renewable diesel or biodiesel. This requirement increases to 50% on May 15, 2026, and 99% on May 15, 2030”.

Reasons For Price Variance

Oil Prices Below $65

OPEC+ Production Boosts For September

Crude oil is trading just below $65, at a current price of $64.72/barrel. This is $1.38/barrel higher than it was last week. 

 

Crude oil is the main ingredient for gasoline and diesel. Per AAA, on average about 50% of what you pay at the pump is the price of crude oil, breaking down as 25% refining, 11% distribution & marketing, and 14% taxes—a helpful breakdown for consumers wondering why they are paying the prices that they pay. Crude Oil is currently trading at $64.72/barrel compared to $63.34/barrel last week and $69 a year ago. 

It’s essential to recognize that fuel prices result from a complex interplay of the factors mentioned above and other regional factors. Additionally, prices may vary by specific regions within Oregon and Washington.

Star Oilco fuel trucks staged for mobile on-site fueling
On-Site Mobile Fueling Benefits -Truck Fleets 1024 768 Star Oilco

On-Site Mobile Fueling Benefits -Truck Fleets

For companies that operate truck fleets, managing fuel consumption is a critical aspect of their operations. Refueling logistics and costs can pose significant challenges. A fuel delivery truck service is also known as fleet fueling, mobile fueling or wet hosing. By incorporating a fleet fueling service that fills their trucks every morning, companies will reap numerous benefits and eliminate additional costs. Through this approach of fleet fueling, efficiency will be improved. Costs are reduced and operations are streamlined. Ultimately, this improves profitability and sustainability for the company and the environment. 

Enhanced Operational Efficiency 

Having a fuel delivery truck fill a company’s truck fleet each morning can significantly enhance operational efficiency. Instead of requiring drivers to waste valuable time searching for gas stations and waiting in queues, the fleet is primed and ready for their daily routes. This allows for optimized productivity as drivers can focus on their core responsibilities through wet hose fueling.

Furthermore, with a centralized refueling system, companies can eliminate the risk of trucks running low on fuel during the day. This minimizes unforeseen delays, ensuring timely deliveries and improving customer satisfaction. The streamlined refueling process also reduces administrative burdens, eliminating drivers to track fuel expenses and submit reimbursement forms.  

Cost Savings and Budget Predictability

Implementing a fuel delivery truck service offers substantial cost savings for companies with truck fleets. By purchasing fuel in bulk, companies can negotiate favorable pricing terms with the fuel supplier. It allows companies to secure discounts or fixed rates. Fuel costs predictability allows for better budget planning, avoiding fluctuating fuel prices.

By eliminating the need for drivers to refuel at public gas stations, the company can prevent unauthorized fuel purchases, fuel theft, and the potential for inaccurate expense reporting. The fuel delivery service ensures that fuel consumption is closely monitored, minimizing fuel misuse.  

In addition, having a dedicated fuel delivery truck also reduces the wear and tear on company trucks caused by constant stops at gas stations. This reduces maintenance and repair costs in the long run. With regular fuel top-ups in the morning, trucks operate at optimal fuel levels, improving engine performance and extending their lifespan.  

Environmental Sustainability

By consolidating fuel delivery through a dedicated truck, companies can contribute to environmental sustainability. Bulk fuel delivery reduces the number of individual fuel stops to gas stations, resulting in reduced carbon emissions. The streamlined fleet fueling process also minimizes fuel spills and or possible leakage from conventional methods. This solution preserves air and soil quality. 

Furthermore, adopting a fuel delivery service encourages alternative and cleaner fuels. Companies can explore options like biodiesel or electric vehicles, and the fuel delivery truck can be equipped to accommodate these eco-friendly fuel sources. By transitioning to greener fuels, companies can reduce their carbon footprint and align with environmental regulations and customer preferences.  

For companies with truck fleets, integrating a fuel delivery truck service offers numerous advantages. Moreover, the streamlined refueling process through fleet fueling or mobile fueling enhances operational efficiency. Your truck fleets will benefit from fleet fueling by eliminating your employees wasting time on the clock with refueling stops. You will also benefit from the minimized administrative burdens. Cost savings are achieved through bulk purchasing, predictable budgeting, and reduced maintenance expenses. This approach contributes to environmental sustainability by reducing carbon emissions and promoting cleaner fuel alternatives.  

By optimizing fuel management and leveraging the many benefits of fuel delivery, companies can drive their fleet operations to new levels of productivity, cost-effectiveness, and environmental responsibility. Embracing this innovative solution not only benefits the company itself but also enhances customer satisfaction and positions the company as a leader in sustainable business practices.
