Wethose Fueling for Construction

Take the headache out of fueling your construction project with a temporary tank on the jobsite.

Star Oilco’s goal as a bulk diesel provider is to keep things simple. Make them easy, predictable, and also get the best price for our customers. We love serving construction sites with our mobile, onsite wet-hose service. But we notice sometimes construction projects can sometimes be tricky to fuel.

Planning your project around fuel is not what anyone wants to do. We make it easy by planning for regular stops at a regular time married with bulk equipment to get your price under control.

Generator Fueling Service

Star Oil provides full-service diesel construction fueling, including DEF.

Make sure your diesel generators, light sets, water pumps, air movers, and other project critical equipment are topped off with diesel and DEF.

It can be difficult to keep a construction site fueled with the stops and starts of projects. The coordination required to keep everything moving full speed while adjusting for the unexpected down times caused by subs, permitting, or weather, can be overwhelming. To “keep things simple,” which is our company motto, we know that locating a bulk diesel fuel tank on your jobsite can simplify your project’s fueling complexity. This provides you with a few days worth of fuel when you need it, while also lowering your cost of fuel.

We find that our customers benefit from lower prices and increased up time by placing a temporary bulk diesel tank in their project’s yard. Call Star Oilco for bulk fuel delivery and ask us about our ability to place a tank on your jobsite in the greater Portland ,Oregon or Vancouver, Washington area.

Diesel storage tanks UL-2085 needed for modern Fire Code 150 150 Star Oilco

Diesel storage tanks UL-2085 needed for modern Fire Code

What is required to install a fuel tank in Oregon?

A Tank that meets International Fire Code is a 2 Hour Fire Guard labeled tank.

In recent years Oregon and Washington have been moving to International Fire Code as their adopted standard. Following California with this higher standard of safety as it relates to liquid fuels.  The new standards are far more involved in their construction and therefore their installation as well. Heavy and far more expensive is the most notable standard of a modern Fire Marshall approved tank.

UL 142 – Double Wall Tanks

The old standard for diesel storage was UL-142 (commonly referred to as double wall or “diked tanks” by fleet managers).  These tanks are still made and extremely common throughout the US. If you see one of these tanks for sale and it looks like a great deal it’s probably because of an upgrade requirement causing them to sell it.  Be aware to check code in your local jurisdiction. These tanks still have a wide market for use especially for agricultural zones as well as temporary use with construction sites.

UL 2085 – 2 Hour Fire Guard and Double Wall Tanks

The new standard for storing diesel for refueling vehicles is the UL-2085. This code has been around for gasoline, it is only new in the way that Fire Marshall’s and local municipalities will require it for diesel fuels.

This standard has been around for a long time but typically was used when storing gasoline or more flammable liquids. That standard now applies to diesel fuels as well if they are being installed to refuel equipment, trucks or any other service.  Its worth noting that boilers, HVAC oil furnaces, and other plumbed stationary applications can still use the UL-142 code. Similarly agricultural use in Oregon is allowed a UL-142 use in most applications.  But for fleet fueling even if only a 100 gallon tank the Fire Marshall’s new standard is the UL-2085 concrete lined fire guard tank. It is also worth noting that if you have an installed UL-142 tank in a commercial or industrial zoned property you probably are okay with grandfathered use. But if you want to change anything the Fire Marshall and local Code Enforcement are going to be looking at the newer and safer standard.

Ask your local Fire Marshall to be sure of what the requirements are.

When discussing diesel storage tank options with your local Fire Marshall it helps to see the reason they have the standards they demand. Also be aware of other requirements that local jurisdiction may have. For instance Portland, Oregon’s Bureau of Environmental Services will often demand a cover be placed over the fueling area, an engineered concrete pad beneath it, as well as a potential oil water separator.  Usually there can be an additional permit and process associated with a tank install to meet the needs of a local Fire Marshall as well.

Two hour fire guard or UL-2085 rated tanks are the new standard in Oregon as we have adopted the International Fire Code. and the picture below says a thousand words. It will protect your property from a lake of fire preventing your diesel fuel from feeding disaster.

This is a great picture of a tank being tested for a two hour fire rating by a vendor of Star Oilco’s. Its speaks to why and what is the concern of your local regulator.

Modern Weld Company is a tank manufacturer out of California that makes great tanks to order exactly perfect for your site.

As they make what you need to the specifications you need you can make the Fire Marshall, local City Code enforcement, and your CFO happy at the same time.  If you have questions about installing a bulk diesel fuel tank to either UL-142 or UL-2085 standards give Star Oilco a call. We can help you meet UL codes for diesel, gasoline, biodiesel, or other storage needs.

Renewable Diesel as a Major Transportation Fuel in California 999 666 Star Oilco

Renewable Diesel as a Major Transportation Fuel in California

RENEWABLE DIESEL IS AVAILABLE

STAR OILCO HAS RENEWABLE DIESEL FOR YOUR FLEET

In the Pacific Northwest we have gone from a complete scarcity of Renewable Diesel availability to several players having terminal positions and this next generation sustainable fuel being readily available.  Star Oilco is ready to serve you with renewable diesel in several blends to meet both your fleet’s financial and carbon budgets.

For years California has lead the west coast with availability of renewable diesel and various blends with both petroleum diesel and biodiesel fuels. This experience is available in the research paper below to help inform your fleet in making decisions about de-carbonizing your fleets.

IS RENEWABLE DIESEL WORTH THE ADDED COST?

Fleet managers fell in love with this exceptionally high quality synthetic diesel fuel. Cleaner and drier than your typical petroleum diesel quite  a few believers are willing to pay a large premium for this fuel.  There are hardcore supporters of this fuel and it’s overall ability to reduce operational cost in far excess of it’s added cost. Which raises the next question.  Is it superior to petroleum diesel?

IS RENEWABLE DIESEL SUPERIOR TO PETROLEUM DIESEL?

The answer points to yes based on initial experience rating the fuel on real world performance, fuel mileage, emissions system maintenance costs, and the much lower CO2 emissions.

The whitepaper shown is probably the most in depth resource for a fleet seeking to understand the potential of renewable diesel for its own use.

Renewable diesel is a next generation diesel fuel.  It has a low CO2 footprint similar to biodiesel, yet it is a high performance fuel that reduces down time and maintenance in urban stop-and-go fleet use.  Long story short, it is an impressive fuel solving many problems associated with modern clean diesel engines.

Given the newness of this fuel along, with the few producers of it, there is a real lack of in depth research on the subject.

If you have any questions about Renewable Diesel please feel free to contact us.

RENEWABLE DIESEL AS A MAJOR TRANSPORTATION FUEL

This white paper is the most in depth examination of Renewable Diesel operating in the real world. It covers a complete view of the product from the perspective of both fleets operating it and regulators seeking to reduce emissions. In our experience this is the most complete document you are going to find to advise a fleet considering using R99 Renewable Diesel.

Whitepaper – Renewable Diesel as a Major Transportation in California: Opportunities, Benefits, and Challenges.
Whitepaper that Gladstein, Neandross and Associates produced for the Bay Area Air Quality Management District and South Coast AQMD.

This report reinforces the manufacturers of renewable diesel’s statements and many anecdotal statements from fleets using the fuel. Renewable diesel sees superior performance in both emission reduction and performance in existing diesel technology. It is a cleaner burning and lower CO2 fuel that also contributes to a lower cost of vehicle maintenance.

According to this August 2017 report, California was on course to see approximately 250,000,000 gallons of R99 fuel sold in the state that year. This is a world-shaking volume of a next generation biofuel. With these readily adopted volumes, no doubt more product will be finding its way into the marketplace. The report cites a CARB expectation of the California Renewable Diesel market growing to over 2,000,000,000 (that’s BILLION) gallons in the next decade.

Bulk Diesel Fuel Frequently Asked Questions

Ultra Low Sulfur Diesel is 15 PPMDyed Off-Road Diesel

Where your diesel comes from and what you need to know about ASTM Diesel Standards and ISO cleanliness code.

Where do Pacific Northwest vendors get their fuel?

In the Pacific Northwest, diesel is fungible. Everyone buys their fuel from each other in some way or another.  

This means that every refiner is typically expecting to mix their diesel and gasoline products. The real difference is in the care a vendor takes to filter the fuel, additize and continuously check their fuel quality. If you are buying at the absolute lowest price possible, know that there is an incentive to skip any added value of quality assurance.

Through its Pacific Operations unit, Kinder Morgan operates approximately 3,000 miles of refined products pipeline that serves Arizona, California, Nevada, New Mexico, Oregon, Washington and Texas. With roots dating back to 1956, it is the largest products pipeline in the Western U.S., transporting more than one million barrels per day of gasoline, jet fuel and diesel fuel to our customers. The company-owned terminals also provide additional services, such as liquid petroleum product storage and loading facilities for delivery trucks.

Diesel Fuels

In the United States, diesel fuel is controlled according the American Society for Testing and Materials Standard D975-97.  This standard describes a limited number of properties that diesel fuels must meet.  It should be noted that the requirements are all performance- based.  They do not mandate the composition of the fuel, only the specific performance related requirements demanded of a fuel for a diesel engine.  The requirements of D975 are described below. 

ASTM Specifications for Diesel Fuel Oils (D975)*

* You can go to the source of ASTM HERE if you have an interest in really getting in depth.

Diesel fuel is characterized in the United States by the ASTM standard D975.  This standard identifies five grades of diesel fuel. We are only going to talk about the two most popular commercially diesel fuel used — No 1 and No. 2 diesel. The ASTM D975 standard is made up of a series of different tests that check the characteristic ranges of a fuel to confirm it is adequate to operate in your equipment. In simple terms, they are checking for specific gravity, the vapor point (when it turns into a gas), the flash point (when it catches fire), the dirt content, water content (how much microscopic entrained water), and a host of other requirements diesel must meet in order to be legal to be sold for use in your engine.

Grade No. 1-D and Ultra-Low Sulfur 1-D: This is a light distillate fuel for applications requiring a higher volatility fuel to accommodate rapidly fluctuating loads and speeds, as in light trucks and buses. The specification for this grade of diesel fuel overlaps with kerosene and jet fuel, and all three are commonly produced from the same base stock. One major use for No. 1-D diesel fuel is to blend with No. 2-D during winter to provide improved cold flow properties.  Ultra Ultra-Low sulfur fuel is required for on-highway use with sulfur level < 0.05%. 

Grade No. 2-D and Ultra-Low Sulfur 2-D:  This is a middle- or mid-grade distillate fuel for applications that do not require a high volatility fuel. Typical applications include high-speed engines that operate for sustained periods at high load. Ultra-Low sulfur fuel is required for on-highway use with sulfur level < 0.05%.

RecologyDealing with Dirty Fuel and Today’s Tier 4 Engines

Water and dirt are the biggest concerns for fuel quality. Why? Because no matter how perfect fuel is refined, these two elements can find their way into fuel and crash its performance. Water and dirt often build up in tanks just from the temperature change between night and day, causing a bulk fuel tank to breathe. Condensation and dust can also find their way into a bulk storage tank. If not addressed, they build up and will cause mechanical failures.

Dirty fuel will cause premature parts failure in equipment of any age. But newer equipment has far tighter tolerances than what we saw in previous decades. Today’s new and improved Tier 4 rail injector engines are more efficient, they burn cleaner, and run better, they are more powerful than ever before. But there are things that make fuel quality more important than ever. Because of the extremely high pressures (upwards of 35,000psi at the injector tip), the possibility of damage from dirty wet fuel is more prevalent than ever. This damage is much more pronounced in newer equipment with High Pressure Common Rail (HPCR) fuel systems. Hard particulate is commonly referred to as “dirt,” but is in fact made up of a wide variety of materials found at job sites (coal, iron, salt, etc.), generated by fuel tanks and lines (rust, corrosion, etc.) and inside engines (carbonaceous materials and wear particles).

Frequent diesel fuel filter changes — as well as the expensive, and time consuming, task of cleaning diesel fuel tanks — have become acceptable periodic maintenance, instead of a warning signal, for diesel engine failure. Diesel fuel filter elements should last a thousand hours or more, and injectors should endure 15,000 hours. However, since diesel fuel is inherently unstable, solids begin to form and the accumulating tank sludge will eventually clog your diesel fuel filters, ruin your injectors and cause diesel engines to smoke.

Symptoms

  • Clogged and slimy filters
  • Dark, hazy fuel
  • Floating debris in tanks
  • Sludge build up in tanks
  • Loss of power and RPM
  • Excessive smoke
  • Corroded, pitted injectors
  • Foul odor

The solids that form as the result of the inherent instability of the diesel fuel and the debris formed in the natural process of fuel degradation will accumulate in the bottom of your fuel tank. The sludge will form a coating or “bio-film” on the walls and baffles of the fuel tank, plug your fuel filters, adversely impact combustion efficiency, produce dark smoke from the exhaust, form acids that degrade injectors and fuel pumps, and impact performance. Eventually, fouled diesel fuel will clog fuel lines and ruin your equipment.

The Bigger Picture: ISO (International Standardization Organization)ISO Chart 1

In today’s world, the definition of what constitutes clean or dirty fuel is critically important and, as such, fuel cleanliness levels are now measured and reported according to the ISO Cleanliness Code 4406:1999. The International Organization for Standardization (ISO) created the cleanliness code to quantify particulate contamination levels per milliliter of fluid at three sizes: 4μ, 6μ, 14μ. Microns.

Fuel Cleanliness vs. Engine Technology

Fuel cleanliness levels using the ISO4406:1999 method were officially documented as a global standard only as recently as 1998 with the development of the Worldwide Fuels Charter (WWFC). Since its inception, the charter has established a minimum cleanliness level for each of the diesel fuels under various available categories around the world.

Most mainstream engine OEM’s now subscribe to these standards. Interestingly (and somewhat troubling to note), however, is that fuel cleanliness levels as specified by engine OEM’s and the WWFC have not changed since their inception in 1998, despite the enormous advances in fuel injection technology. This relationship is best represented in the previous table that identifies the advances in fuel injection systems and clearly highlights how OEM’s and the WWFC have not responded to reduce fuel cleanliness in accordance with advancements in technology.

Diesel Fuel Injection – Advancing Technologies & Cleanliness Levels

ISO Chart 4This table  identifies that, over time, fuel injector critical clearances have halved and fuel pressures have doubled, yet the level of fuel cleanliness being specified has not changed in accordance with such advancements. In fact, the same cleanliness levels specified in 2000 are still being used today despite these magnificent technological design advancements by engine manufacturers worldwide.

Leading fuel injector manufacturers around the world have clearly identified and communicated that they require ULSD fuels with ISO fuel cleanliness levels as low as ISO12/9/6 to maintain ultimate performance and reliability. It is here where we see an enormous mismatch in what the fuel injection OEM desires as a fuel cleanliness level, to what the engine OEM’s and the WWFC are advising the industry. The following table identifies the discrepancies in fuel cleanliness levels.

Damage Caused by Hard Particulate

Hard particulates cause problems with moving parts in the fuel system. This can lead to starting problems, poor engine performance, idling issues and, potentially, complete engine failure. All too common, hard particulates damage engines.

The spray pattern generated by the HPCR injector is critical for proper combustion and overall fuel system performance. (1) sm-injector-with-red-light-Bosch

It must be extremely precise in terms of quantity, distribution and timing. Ball seat valves are sealed with balls that are only 1mm in diameter. A good seal is absolutely necessary for proper injection. Damage from erosive wear, such as shown below, will cause over fueling, leading to decreased fuel efficiency and eventually shut you down altogether.

hpcr injector damaged by hard particulate(3) high-pressure-fuel-system-wear

Pump performance can also be compromised by scoring and abrasive wear. These issues are magnified by tighter tolerances and extreme pressures in HPCR engines. In these circumstances, it is the smallest particles (1-5 microns in size) that cause the most damage, virtually sand blasting part surfaces.

Allowable Levels of Hard Particulate 

(4) dirt-in-vs-allowed-in-1000-gal-dieselIn some parts of the world, 10,000 gallons (38,000 liters) of “typical” diesel contains 1-1/2 lbs (700 grams) of hard particulate; this is 1000 times more than the 1/4 oz. (0.7 grams) per 10,000 gallons (38,000 liters) that is allowed by the cleanliness requirements of high pressure common rail fuel systems. In reality, there is no “OK” level of hard particulate. Injector manufacturers are very clear that damage caused by hard particulate reaching the engine is not a factory defect, but rather the result of dirty diesel that is not fit for use in HPCR fuel systems. At the end of the day, the end user is responsible for the fuel he puts into his equipment, and the consequences thereof.

How Dirt Enters Fuel

Dust and dirt are all around us, especially on job sites. Diesel fuel is fairly clean when it leaves the refinery but becomes contaminated each time it is transferred or stored. Below you will find some of the key contributors of fuel contamination:

Pipelines: Most pipelines are not new, and certainly not in pristine condition. Corrosion inhibitors are added at most refineries to help protect pipelines, but rust and other hard particulate is nevertheless picked up by the fuel that flows through them.

Barges and rail cars: How often are they drained and scrubbed out? What was in the last load? Where did it come from? How much of it was still in the tank when your load was picked up? How long was it in transit? Is the tank hermetically sealed? There are many opportunities for contaminants to make their way into the fuel.

Terminal tanks: Terminal tanks usually see a high rate of turnover, so there is not much time for the fuel to pick-up contamination from outside ingress. Has the tank ever received a “bad load” from a pipeline or a barge? Has larger dirt had a chance to settle on the bottom of the tank? How often has it been cleaned out? Was it just filled? Did the bottom get churned up in the process? How full was the tank when your fuel was loaded into the delivery truck? There are many variables that can affect fuel cleanliness.

Delivery trucks: All the same issues that apply to stationary tanks also apply to tanker trucks, except that truck tanks never get a chance to settle. In addition, have you ever considered how much dirt gets into that tanker while it is delivering fuel to a customer, potentially a customer in an extremely dusty environment? As fuel flows out, air is sucked in to displace it. Is there anything protecting the inside of the tank from all the dust in the air? Generally not. Venting is typically completely unprotected, as seen in the image to the right.

Storage tanks: Onsite bulk storage tanks typically see less rapid turn-over than terminal tanks. In addition to those issues, yard and jobsite tanks can also develop serious problems with other sources of contamination, such as the ingress of dirt and water, condensation, rust, corrosion, microbial growth, glycerin fall-out and additive instability. Time and temperature become big factors affecting fuel quality.

Dispensing process: How far does your diesel need to travel between the bulk tank and the dispenser? The more pipe it runs though, the more potential there is for contamination. Are your dispenser nozzles kept clean? Are they ever dropped on the ground? Then what? What about the vehicles’ fuel tank inlets, are they clean? Think about the extremely tight tolerances in your fuel system, then take another look at housekeeping issues. You will see them through new eyes.

Onboard fuel tanks: Contamination continues even after the fuel is in the equipment. What has that tank seen in the past? Has it been left stagnant for long periods? What kind of protection is there on the equipment’s air intake vents? Heavy equipment does hard, dirty work.

Engines: Unfortunately, even if the fuel in your tank could be perfect, additional contamination is generated by the fuel system itself. Wear particles are created by mechanical friction. High heat and extreme pressure generated inside the modern engine, lead to coking and the creation of carbon products at the injector. Much of this internally-produced particulate is returned to the fuel tank, along with the unburned diesel.

The Bottom Line

No one gets special fuel, no one has better fuel, no one has cleaner fuel. Diesel fuel vendors get the same fuel, from the same pipeline, delivered to the same terminals. We all wait in the same lines with our tank trucks to get that same fuel. So ask yourself: Given that the fuel is the same, what sets one vendor apart from all the others?

Do you have a bulk diesel storage tank?

Does that tank seem to have water in the bottom of it and you can’t seem to figure out where it’s coming from?

You call your diesel supplier and they say they know it isn’t them. If that’s your experience, Star Oilco can explain where that water is probably coming from. With the help of Hydrotex, Star Oilco can also lab test your fuel quality and prove we are in improving it as well.

desiccant filter in field

All storage tanks are different. But for the most part, if your tank seems to take on water randomly. It’s probably from the tank breathing. Especially if you have a large above ground tank. In fact, if you tracked it on a calendar it probably happens the same time of year in conjunction with a weather pattern your tank responds to.

How it works is as the temperature changes the tank’s space that is not filled with fuel will breathe in and out. The temperature and air pressure move air in and out of the tank. As does dispensing fuel out of the tank and then refilling the tank. When that happens, especially if you have a significant amount of humidity in the air or misting rain, water makes it’s way into your fuel supply. As temperatures change, moisture is drawn into the tank, condenses on the inner wall of the tank, and then deposits itself on the bottom of the tank.

This water not only poses a risk to your engines, but if your fuel isn’t treated for stability and performance, that fuel is guaranteed to start growing bugs and algae that will spread throughout your fleet and will have your mechanics spinning filters and dealing with random problems due to this diesel biological growth.

This problem is also exacerbated by ineffective fuel additives trying to keep your fuel dry, clean and safe for your injectors to process, which ensures that water does not get absorbed by your diesel. A single drop of water falling out of solution in today’s high pressure fuel rails and your engine can blow an injector.

HOW DO YOU SOLVE WATER IN YOUR DIESEL TANK?

ANSWER: DESICCANT BREATHERS ON YOUR VENTS

Desiccant diagram

Star Oilco recommends Donaldson desiccant filters, given their excellent full line of products and support. More on the full Donaldson Clean Dry Fuel program here: Donaldson Clean Diesel Kits Brochure.

The Donaldson desiccant breaker mounts to the top of a tank at it’s vent point. This addition seals the point of failure for water to get into your tank. Though in some cases it doesn’t stop 100% of water from ending up in your fuel tank, it definitely guarantees you know where it won’t be coming from, the environment around your tank.

(NOTE: If dealing with underground storage tanks also be aware that if you seal the vent with a desiccant filter and you still have incident’s of water, it might be a leak in the bottom of the tank where rain water is making its way into the tank.)

By using Donaldson filters, Star Oilco also gains the benefit of support from Hydrotex PowerKleen diesel fuel lab to analyze fuel to guarantee that the before and after samples of the fuel are moving as expected and the problem is solved. Running diesel samples can cost as much as $200 each time–having a partner that backs up our solutions with ASTM and ISO measured verification is a must.

The first step in getting better performance from your diesel fuel is to test your bulk diesel storage tank.

What is Clean Diesel? 

Clean diesel is free of the contaminants that harm modern diesel engines. Today, there is a gap between ASTM diesel standards and the ISO cleanliness standards needed for use in high pressure common rail engines. Anyone operating a modern clean diesel engine is seeing the effect, including injector replacement, DPF regeneration, and a host of other fuel quality related maintenance concerns we never saw twenty years ago. On top of all of that, today’s refined diesel fuels are less storage stable then ever before. What is on the bottom of your bulk tank can also complicate matters further. When diesel is bought wholesale it typically meets and exceeds ASTM required industry standards, but almost always requires additional filtration to avoid excessive engine wear and premature part failures.

Having clean diesel requires an additional amount of care. Namely, you need to make sure that the fuel is aggressively filtered at 4 microns to catch the microscopic particles that are big enough to damage your modern diesel engine’s high pressure fuel rail system. Furthermore, clean diesel is fuel that is free of water and stabilized with Premium Diesel to guarantee no bacteria, yeast and other creatures can grow and further contaminate the saddle tanks on your trucks.

For more on clean diesel, see Donaldson’s description of “The New Clean” for an in-depth explanation of what ISO cleanliness and filtration mean for your diesel fleet.

Making Diesel Cleaner!

Knowing the quality of your fuel is the first step. This is done by taking samples off of the bottom of your bulk storage, as well as a representative sample from your fuel dispenser. Lab tests of those samples will tell you if you have water, biological growth, or dirt issues with your storage. The contaminants in the tank being sampled are almost always visible, which is to say that they look horribly ugly. If your fuel quality assurance has been on autopilot, do not be surprised if you find this. After gathering knowledge about your fuel, the next step is to get your fuel quality clean.

Filtration and tank bottom sampling is the start. Beyond that, the only way to improve your fuel quality performance is to filter your fuel, ensure water is not getting into the tank through condensation, and additize it with a Premium Diesel additive to upgrade the performance of the fuel. Many fleets today are seeing injector wear and continual problems with particulate trap maintenance. This is a combination of water in fuel and microscopic particles not captured by a 10 or 30 micron filter used at most diesel dispensers. You have to filter more aggressively than this.

The first step is sampling your bulk diesel tank. We check your bulk tank for water and dirt, and make sure to meet the specifications your engine is built for. Star Oilco can help by providing a complementary diesel test for those fleets interested in taking control of their fuel quality assurance. Usually when testing fuel, we take a sample off of the tank bottom as well as a representative sample out of the fuel dispensing nozzle.

What we usually find is ASTM specification diesel fuel (it meets ASTM spec) that is higher than you’d want (still in spec) for water with far more dirt than the OEM’s would want to see in your engine. This dirt fails to be within the “ISO Cleanliness” specifications recommended by engine manufacturers. Usually we also see water on the bottom of the fuel tank, which is a likely source for future or current biological growth in your fuel tank.

Star Oilco can help you fix this! The first step is to sample your fuel tank.

NOTE: If you have a current biological growth problem in your bulk fuel tank or fleet, your first step is to treat that effected fuel with a diesel microbiocide to kill the bugs growing in your tank. For more on this, see our Valvtect Plus 6 Diesel Microbiocide page.

Fixing the problems with bugs growing in your diesel

What to do about Biological Growth in Diesel Fuel.

Fuel Marketer News has two great articles on biological growth in fuel tanks. Star Oilco as a diesel fuel delivery provider in Oregon and Washington is all to familiar with this emerging problem with ultra-low sulfur bio-diesel blend fuels.

Where there is water, bugs can grow in diesel.

The Fuel Marketer News articles below:

Fuel System Bugs Drain Revenue, and
Bugs Cause Fuel System Damage (part 2)

These articles in a nutshell are about the costs, impact, and ongoing effect of bugs growing in fuel as a real industry issue. If you have filters clogging in your fleet–much like a heart attack–it’s not a symptom, it’s a late-stage problem. Clogged filters slow down your fleet fueling and add serious cost to your vehicle maintenance. Lost power on the highway also slows your drivers down, escalating the drain on efficiency fuel that bugs may be causing.

Star Oilco can cure these problems, both with stopping hum-bug growing in your diesel tanks, as well as ensuring that the water those fuel bugs live in stops migrating into your tank. We will help you solve diesel fuel quality issues.

The first step is for Star Oilco to test the bottom of your fuel tank, as well as take a representative nozzle sample that would go into your trucks. We will show you where your fuel quality is today and come up with a collaborative way to move that into exceeding ASTM diesel specification, as well as aligning with engine manufacturer’s ISO specifications for diesel fuel cleanliness.

If you have questions about fuel quality assurance, Star Oilco has solutions. Left unattended, your diesel fuel will grow bugs, alga, yeasts, and other biological active destroyers of fuel quality. If you need to treat your fuel to kill humbugs like these, Star Oilco recommends Bioguard Plus 6 as your go-to solution. It is both a biocide that kills the bugs growing in fuel, as well as a heavy duty detergent to clean up other deposits as well.
