Saving Money On Rising Fuel Costs

Here are some fuel-saving tips that a fuel delivery company can offer to their construction customers to help them save money on fuel.  

Optimize Routes and Schedules 

Plan deliveries to minimize travel distances and combine multiple stops whenever possible. This will reduce fuel and time costs and emissions from vehicles. Additionally, it will increase efficiency by reducing wait times and allowing for more deliveries to be made.

Reduced Costs & Environmental Impact: 

  • Minimize travel distances and combine deliveries to save on fuel and related expenses. 
  • This strategy also reduces emissions from our delivery vehicles, contributing to a greener future. 
  • Enhance your efficiency. By combining stops, we streamline delivery routes, reducing wait times and allowing for more deliveries in a shorter amount of time. 

Promote Proper Equipment Maintenance 

Every minute counts on a construction site, but even short breaks can lead to unnecessary engine idling. Idling not only wastes fuel and increases costs, but also contributes to air pollution. With Portland’s new fossil-based diesel fuel restrictions within city limits, with the larger effort to achieve net-zero carbon emissions by 2050, this is a great time to consider how your business operations can reduce its fuel consumption and overall work to achieve net-zero carbon emissions. To promote a more environmentally friendly work environment and keep fuel costs down, employees should work together to discourage idling. A simple yet powerful solution is to remind workers to completely shut down engines during breaks, no matter how short. This small step can significantly reduce our overall fuel consumption and create a cleaner, healthier site for everyone. 

Idle Reduction: 

  • Even short breaks can lead to unnecessary engine idling, wasting fuel and increasing costs. 
  • Idling also contributes to air pollution, impacting the environment and worker health. 

Simple Solution, Big Impact: 

  • To promote a cleaner, more cost-effective worksite, all employees should work together to discourage idling. 
  • Remind workers to completely shut down engines during breaks, no matter how short. 
  • This small step can significantly reduce fuel consumption and create a healthier environment for everyone. 

Invest in Fuel-Efficient Equipment 

Consider upgrading to newer equipment models known for better fuel economy. By investing in fuel-efficient equipment, businesses can reduce their fuel costs and reduce their carbon footprint, as newer machines tend to be more fuel-efficient. Plus, newer models tend to have fewer parts and are more reliable, so businesses can expect to spend less on maintenance and repairs. 

Upgrading to fuel-efficient equipment: 

  • Reduces fuel costs for construction projects. 
  • Lowers a company’s carbon footprint by minimizing emissions. 

Newer equipment: 

  • Has fewer parts, simplifying maintenance needs. 
  • They also tend to be more reliable, leading to less downtime and repair expenses.

Portland Retail Fuel Price Variance

Fuel Market News

Fuel prices are up for the third consecutive week as prices jumped over $0.20/gal on gas and $0.12/gal on diesel this past week. Rack averages in Portland jumped $0.29/gal for regular E10 gasoline, and $0.13/gal for B5 & B20 diesel. The average retail price for gas in Portland has increased by $0.22/gal over the last two weeks. In part, this is due to current geopolitical tensions between Iran and the U.S along with higher crude oil prices, extreme storm weather across the nation, and refineries beginning to switch back to summer blend gas as we approach the spring season starting March 20th. We should expect prices to continue to trickle upwards as the switch to summer blend gas creates logistical and operational challenges affecting pricing and distribution.

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 Above $60

OPEC+ Strategic Pause

Crude oil is trading above $60, at a current price of $63.73/barrel. This is $1.78/barrel higher than the week prior.

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 $63.73/barrel compared to $61.95/barrel last week and $71 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.

Winter Diesel Additives For Portland Weather

How to Prevent Diesel Fuel from Gelling in Low Temperatures

When the chill of winter arrives in Portland and across Oregon, diesel engines face a unique challenge. Cold temperatures can transform diesel fuel from a fluid state into a gel-like substance, leading to significant engine issues. Understanding and combating these cold-weather challenges is crucial for optimal diesel performance

Understanding Cold-Weather Diesel Challenges

As temperatures drop in Portland, diesel fuel, known for its efficiency and power, encounters an Achilles’ heel—the tendency to gel. This gelling occurs primarily due to the crystallization of the waxes naturally present in diesel. When these waxes crystallize, they can clog fuel filters and lines, hindering fuel flow and causing engines to struggle or even fail to start. This is a common situation for those familiar with traveling in colder areas of Oregon, emphasizing the importance of preventive measures to ensure the uninterrupted performance and reliability of diesel machinery and vehicles.

The Science Behind Fuel Gelling and Wax Crystallization

Diesel fuel has a natural reaction to cold weather because it contains paraffin waxes. These waxes are helpful in warm weather because they provide energy to the fuel. But when temperatures get colder, the waxes start to solidify, just like water turns into ice when it freezes. As the temperature drops, the waxes form crystals that grow larger and make the fuel thicker.

This process is called crystallization, and it makes the fuel less fluid, which can cause gelling. When diesel fuel gels, it becomes thick and sludgy, like a semi-solid. This makes it difficult for the fuel to flow through the engine, which can lead to serious problems for diesel engines.

The formation of these wax crystals is a big issue because they can clog fuel lines and filters, stopping the engine from running properly. When fuel can’t move smoothly through the system, engines can stall or fail to start altogether. This is why gelling is such a major concern for diesel engines during cold weather, and it’s important to find solutions to prevent it from happening.

Introduction to Cold Flow Improvers

To address the issue of gelling, additives known as cold flow improvers have been developed. These chemical additives prevent diesel from gelling in cold temperatures by targeting wax crystals in the fuel. They keep these crystals small and dispersed, ensuring diesel remains fluid and pumpable. This functionality is crucial for maintaining smooth engine operation and fuel system efficiency in cold climates, such as those experienced in Portland and other areas of Oregon, without altering the diesel’s inherent properties.

How Cold Flow Improvers Work

When diesel fuel gets cold, it can start to thicken because wax crystals form inside it. These wax crystals can grow and stick together, which makes the fuel hard to flow through the engine. Cold flow improvers are special additives that are designed to stop this from happening.

At a molecular level, cold flow improvers change how diesel behaves in cold temperatures. They target the process where wax crystals form and grow. Normally, when it gets cold, these crystals start to connect with each other, and that can cause clogs in fuel filters or slow down fuel flow. But when cold flow improvers are added to diesel, they act as nucleation inhibitors. This means they stop the wax crystals from growing too big or interlocking with each other.

Because of this, the fuel stays fluid and can still flow smoothly, even when temperatures drop. Cold flow improvers help ensure that diesel engines run properly in cold weather by keeping the fuel from gelling up. This keeps fuel filters from clogging and helps the engine perform better, so vehicles and equipment can operate reliably, even in the winter

Benefits of Cold Flow Improvers

Cold flow improvers have proven valuable for businesses in Portland, OR, that rely on diesel-powered equipment, especially during the chilly, wet winter months. Here are a few examples of how these additives can benefit equipment performance:

1. Reduced Fuel Gelling in Cold Temperatures

  • Problem: Diesel fuel can start to gel when temperatures dip, leading to clogged fuel lines and filters. This is especially problematic for trucks, construction equipment, and other diesel-powered machinery that operates outdoors.
  • Solution: Cold flow improvers lower the temperature at which diesel fuel thickens, preventing gelling. This keeps machinery running smoothly during cold snaps, even when temperatures fluctuate widely across Portland’s winter.

2. Improved Fleet Reliability for Delivery and Transport Services
  • Problem: Delivery trucks and transport services often face delays or downtime due to fuel issues in the winter, as fuel flow can slow or stop altogether.
  • Solution: By using cold flow improvers, delivery companies keep fuel flowing reliably in suboptimal weather. This reduces the risk of late deliveries and unplanned maintenance, helping fleets stay on schedule and lowering operational costs.

3. Enhanced Performance for Emergency Backup Generators
  • Problem: Many commercial and industrial businesses in Portland rely on backup generators to kick in during outages, but generators need reliable fuel flow to work properly in cold temperatures.
  • Solution: Adding cold flow improvers to generator fuel storage ensures that fuel remains liquid and usable during winter, helping businesses maintain critical operations in power outages.

4. Lower Maintenance Costs for Construction Equipment
  • Problem: Heavy equipment used on construction sites, especially in winter months, can suffer from fuel blockages, leading to breakdowns and costly repairs.
  • Solution: Cold flow improvers prevent fuel line blockages and improve equipment reliability, reducing maintenance expenses and keeping projects on track, even during Portland’s colder periods.

By adding cold flow improvers, businesses across Portland can minimize disruptions due to cold weather, maintain reliable equipment performance, and reduce winter-related repair costs. This small addition to fuel management can make a significant difference in operational efficiency and reliability during the cold months.

Monitoring Fuel Usage

Using cold flow improvers offers several essential benefits for diesel engines in cold weather:

Prevent Fuel Gelling and Filter Clogs
These additives keep wax crystals small, preventing filter blockages.

Enhance Fuel Flow and Engine Performance
Improved fluidity leads to better engine efficiency and reliability.

Prevent Downtime
Using cold flow improvers can help avoid costly equipment downtime due to fuel system gelling.

Ensure Operational Reliability in Cold Climates
These additives are vital for the consistent performance of diesel engines in winter conditions.

Cost-Effective
Cold flow improvers enhance fuel efficiency and reduce maintenance needs, offering long-term cost savings.

Biofuels industry exceeds EPA’s expectations

Biofuels Industry Surpasses Expectations with a Massive Production Rise

Based on the data, biomass-based diesel production has increased massively in the United States, including biodiesel, renewable diesel, sustainable aviation fuel, and heating oil. Biomass-based diesel was expected to produce 4 billion gallons in 2023. Biofuel production and use increased by one billion gallons from last year to this year, which is a big jump. As a result of this achievement, a breakthrough has been achieved. The industry has surpassed what the EPA once thought was impossible with the development of advanced biofuels derived from sustainable sources.

So the real question is, what if we don’t choose biodiesel or renewable diesel over petroleum diesel for our diesel engines?

Biofuel production from plant oils and renewable crops for clean diesel alternatives
  • Biofuel production soared in 2023, exceeding EPA goals.

  • US biomass-based diesel production (biodiesel, renewable diesel, SAF, heating oil) reached 4 billion gallons.

  • Biofuel production and use jumped by 1 billion gallons year-over-year.

Clean Fuel Industry Beats Regulations in Decarbonization Push

While the Clean Fuels Alliance urged the EPA to set even more ambitious goals, like increasing biomass-based diesel production by 500 million gallons a year over the next three years, the EPA has taken a more conservative approach. Regulations aren’t keeping up with the industry, but it’s not waiting for them. Clean fuels are becoming more accessible and heavy-duty transportation fuels used by aviation and maritime are getting decarbonized. The industry has shown its ability to grow quickly and sustainably thanks to this collaborative effort.

  • Clean Fuels Alliance pushed for aggressive EPA goals: 500 million gallons annual increase in biomass-based diesel production for 3 years.

  • EPA’s finalized standards took a cautious approach.

  • Oil and gas producers, refiners, distributors, and retailers don’t have to wait for strict regulations to act (producers, refiners, distributors, retailers).
  • Industry collaboration demonstrates the potential for rapid, sustainable growth.

Decarbonization concept with CO2 reduction icons over a globe in green grass symbolizing clean energy

Despite this year’s achievements, the Clean Fuels Alliance remains focused on the future. There’s so much potential in sustainable biofuels that we think the EPA hasn’t tapped into yet. Supporting biodiesel, renewable diesel, and SAF production can help achieve clean energy progress.

In reality, why wouldn’t we make the switch to lower our carbon emissions today?

The Future of Diesel Fuel

Diesel Fuel In Oregon and Washington

Star Oilco has been getting questions on the changes of diesel in Portland, Oregon.  If you have not noticed, many diesel pumps at retail gas stations and cardlock have seen changing stickers on the face of the fuel pumps.  As of July 1st, 2024 the City of Portland requires a minimum 15% biofuel content of all diesel sold.  This policy is called the Portland Renewable Fuel Standard.

This has caused quite a few changes in what fuel pumps have for fuel.  Diesel fuel buyers are noticing the bright yellow color of B20 biodiesel, the water clear color of Renewable Diesel or a a mix of several fuels tinting the color of their diesel.  This trend is bigger than just Portland.

Today on the west coast there are a variety of product label stickers you will see on diesel pumps.  These show the variety of diesel fuel specifications that are being sold to diesel vehicles today. Blends of petroleum ultra low sulfur diesel, R99 (99%) renewable diesel, and B99 (99%) Biodiesel are combined to meet the market needs of the diesel we all buy.

This change is because of a combination of pure market forces, government rules and local decisions by fuel haulers.  Today’s diesel not only has a commodity market for the fuel it also has a market for CO2 credit value and a cap of total petroleum diesel fuel that can be sold into a west coast state with a “Cap and Investprogram requiring blends of low CO2 biofuels, the liquid fuels sold for vehicles.

Add on top of these market forces, advances in technology used to make the liquid diesel fuel.  The diesel arriving at truck stops, gas stations, cardlock or out of a hose from a bulk truck has been changing and it’s often in good ways.  Knowing how can be helpful in navigating why diesel may cost one price or another and may have a need or maintenance that another fuel does not.

THE RISE OF RENEWABLE DIESEL

Renewable diesel is a synthetic diesel fuel made from the same feedstock as biodiesel, but the finished product is hydrocarbon diesel.  Though it is a biofuel, it is also diesel. For fuel regulation they refer to it (as well as biodiesel) as “Biomass Based Diesel” for labeling at the fuel pump.

There have been billions of plant capacity brought online for renewable diesel.  During the COVID collapse of fuel prices a number of petroleum refineries shut down, then upgraded their technology to make hydrocarbon diesel fuels out of the very biobased fats, oils, and greases biodiesel is made from.  These refineries use hydrotreating technology just like they do with a crude petroleum to make an actual hydrocarbon diesel molecule.   With this technology adoption to make diesel and jet fuels from vegetable oils and animal fats billions of gallons of low CO2 diesel fuels are coming on the market and governments are requiring it’s use, such as Portland’s Renewable Fuel Standard.

Renewable Diesel Consumption it the US Source: Alternative Fuels Data Center

THE AVAILABILITY OF BIODIESEL

The US makes billions of gallons of biodiesel.  A fuel that’s quality and performance continues to improve.  If you are not a fan of biodiesel in your fuel thinking strategically about the fuel will likely benefit your fleet operation.  The big concern with diesel fuel in a ultra low sulfur world is water and dirt suspended in the fuel affecting the performance of diesel emission systems.  With clean and drier quality specifications of B99 blend stocks today versus a decade ago the use of this fuel has grown substantially especially in the truck stop market.

When crude petroleum prices are high and therefore refined diesel prices are equally as high biodiesel is often an extremely competitive fuel.  If a large seller of diesel (including petroleum refiners) can pick up pennies per gallons on millions of gallons sold they will do so.  Therefore Biodiesel is often seen in diesel in small blends even if you do not see a label on retail pump.  For blends above 5% a label is required for retail fuel sales. RTHWEST?

Above are a variety of labels used to denote what fuel blend is coming out of a retail diesel dispenser. Feel free to call Star Oilco at 503-283-1256 if this confuses you and you want it explained.  We would be glad to do so.

These labels can be found together often at one pump.  All state and Federal standards require ultra low sulfur diesel for any on-road diesel sale.  The Federal standards also adopted by the states require a disclosure at the fuel pump if a blend is above 5% biodiesel.  The max allowable blend of biodiesel for diesel truck manufactures is a 20% blend.  If a truck dealership says that you cannot blend biodiesel up to 20% they need to take that up with the Federal Government because they need to support it.  This is why the label shows a blend may contain between 5% and 20% biodiesel content.

Renewable diesel is a hydrocarbon diesel. 

 

It is diesel meeting the ASTM D975 specification for diesel. 

Retailers selling blends of R99 in their fuel do not need to label it given this.  They still do label it given the benefits of the fuel’s performance and that customers are seeking that fuel.

Many retail places will have stacked labels showing they may be blending 5% to 20% biodiesel as well as may be adding R99 Renewable Diesel to the fuel as market conditions dictate it is the more cost competitive fuel.  When seeing a label like this it can usually be assumed they are blending a R80 (80% Renewable Diesel) and a B20 (20% Biodiesel) blend of fuel.  This blend is actually believed by some to be a higher performing fuel seeing better performance that a R99 or B20 fossil fuel blend.

Fossil fuel diesels are being replaced or blended with biomass based diesels.  Be it Renewable Diesel or Biodiesel.  These blends are driven by more than one industry requirements, government rules, or other market forces. One of these being Portland’s banned on petroleum diesel through the Renewable Fuel Standard (RFS). This is resulting in an increase of low-carbon biofuel blends that will ultimately move to a mix of 99% renewable fuel requirement by 2030.

Renewable Diesel and Biodiesel Blend fuel dispenser label.

The big drivers are industry specification for fuels (both labeling as well as chemical characteristics), state rules on selling these fuels, their quality assurance as well as CO2 content, and of course the market forces.  Market forces being the supply and demand availability of fuel needed to meet customers.  Less fuel available to sell means higher prices for customers.

A decade ago the market for diesel was far simpler. Though you had biofuels and some blend mandates basically you had a diesel specification accepted and the daily price as tracked by a lighted retailers sign, a wholesale market average or spot buying by some customers.   Today this market is far more complicated by government regulation on the west coast.  There are three big programs at state levels impacting this.

State Fuel Rules cause a unique need for one state or another. Whereas twenty years ago if Oregon or Washington fuel was selling for more than the Gulf Coast you might see brokers bring fuel into the region then driving down high prices.  With the creation of various complex and unique rules on diesel, imports of fuel to these low CO2 fuel states has dropped.  The amount of people moving product into west coast states has dropped.  The big rules causing this are the Cap and Invest programs of the West Coast states, the Low CO2 Fuel Standards of the states, and the fuel blend mandates of various jurisdictions of these states. For instance California now requires all off-road diesels but 99% renewable diesel.  Portland, Oregon also has a CO2 requirement and minimum 15% blend of biomass based diesel on all fuel sold in the state.

WHAT ARE THE DIESEL FUELS AND THEIR SPECIFICATIONS

Petroleum Diesel:
ASTM D975 Specification.

The ASTM D975 is a series of tests used to maintain consistent industry standard product performance for diesel fuel.  It includes among several tests cloud point, cold filter plug point (CFPP), several masurements of diesel fuel operability performance, intrained water content, sediment, carbon residue, ash, distillation, viscosity, sulfur, copper corrosion, cetane number, cetane index, aromaticity, and conductivity.

Renewable Diesel:
ASTM D975 Specification.

Renewable Diesel is following the same series of tests as petroleum refined diesel fuels.  It is the same ASTM D975 specification. Though Renewable Diesel has some different properties that exceed the ASTM specification of diesel.  Renewable Diesel is highly prized as a fuel because it typically is a cleaner and drier diesel fuel than petroleum diesel. This being seen by the tests on sediment and water content in a parts per million level.  Renewable Diesel content in diesel fuel can also be tested for looking for a C14 molecule (the chain typically created in a Hydrotreated Diesel process from fats, oils and greases.

Biodiesel (Methyl Esther):
ASTM D6751 Specification.

The ASTM for Biodiesel tests a mono-alkyl esters of long chain fatty acids derived from vegetable oils and animal fats. The testing for quality assurance covers an analysis for flash point, methanol, water and sediment, kinematic viscosity, sulfated ash, oxidation stability, sulfur, copper strip corrosion, cetane number, cloud point, acid number, carbon residue, total and free glycerin, phosphorus, reduce pressure distillation temperature, atmospheric equivalent temperature, combined calcium and magnesium, and combined sodium and magnesium.

For more on Biodiesel Use and Handling the National Renewable Energy Laboratory has a great book on the subject.

THE HISTORY OF DIESEL FUEL SPECIFICATIONS IN THE UNITED STATES

In the 1990’s the US EPA passed rules that demanded a phase out of sulfur in diesel fuel.  The presence of sulfur was very good for the fuel’s storage stability as well as fuel lubricity, but was horrible for air quality.   Additionally the big smog contributor was NOx (nitrous oxide) which was one of the EPA’s reason’s for pulling sulfur out of diesel.  For the EPA to get engine manufacturers to treat the NOx emissions at the tailpipe they needed all the sulfur gone (ultra low sulfur diesel) for modern diesel emission systems to be able to eliminate NOx as well as a host of other pollutants including particulates.

The story of changing diesel fuel standards in the US under the EPA is one of removing sulfur from our diesel fuel.  In 1996 the fuel refiners and sellers of diesel had to move the sulfur content of the fuel sold for on-road purposes to below a 500 parts per million standard. Commonly referred to as Low Sulfur Diesel fuel.   In 2006 the standard moved to a maximum of 15 parts per million of sulfur for all on road fuels.

In 2006 while the sulfur content of fuel was dropping the City of Portland released the first mandated blend of biodiesel content.  This being a 5% biodiesel blend.  The next year, the State of Oregon followed with its own Renewable Fuel Standard requiring this throughout the state.  This began the expectation of biodiesel in most diesel fuel in the Portland, Oregon area.  Washington also passed a similar policy for blending biodiesel but the enforcement and need for the fuel is less specific at Washington fuel pumps.

Renewable Diesel vs Biodiesel

What’s the difference and how do they compare in price? 

If you are looking for a cleaner and greener alternative to diesel fuel, you might have come across two options: renewable diesel and biodiesel. Both fuels are made from organic sources, such as vegetable oils and animal fats, but they have different production processes and properties. In this blog post, we will compare renewable diesel and biodiesel in terms of their pros and cons, as well as their prices and incentives in Oregon. 

What is Renewable Diesel? 

Renewable diesel is a fuel that is chemically identical to petroleum diesel, but it is made from renewable raw materials through a process called hydrotreating. Hydrotreating removes impurities and oxygen from the feedstock, resulting in a pure and refined fuel that can be used in any diesel engine without modifications or blending. Renewable diesel (R99) has a high cetane number, which means it ignites easily and burns efficiently. It also has a low cloud point, which means it can withstand cold temperatures without gelling or clogging filters. 

What is Biodiesel? 

Biodiesel is a fuel that is made from renewable raw materials through a process called transesterification. Transesterification converts the feedstock into fatty acid methyl esters (FAME), which are then blended with petroleum diesel at various ratios. Biodiesel can be used in most diesel engines, but it may require some modifications or adjustments depending on the blend level and the engine type. Biodiesel has a lower cetane number than renewable diesel, which means it may not ignite or burn as well. It also has a higher cloud point than renewable diesel, which means it may gel or clog filters in cold weather. 

The cost of renewable diesel and biodiesel depends on various factors, such as the type and availability of feedstock, the production process, the market demand, and the government incentives. In general, renewable diesel is more expensive than biodiesel, as it requires more complex processing and higher quality feedstock. According to the U.S. Energy Information Administration (EIA), the average wholesale price of renewable diesel in California was $3.06 per gallon in October 2021, while the average wholesale price of biodiesel was $2.76 per gallon in the same month. However, both renewable diesel and biodiesel can benefit from federal RIN’s and state credits such as the low carbon fuel standards, which can lower their effective prices and make them more competitive with petroleum diesel. As of July 10th of 2023 renewable diesel (R99) in Portland Oregon was 60 cents higher than biodiesel (B99). 

 Renewable Diesel vs Biodiesel Carbon Intensity 

According to CARB, the carbon intensity of biodiesel ranges from 14.85 to 67.45 gCO2e/MJ and, renewable diesel ranges from 15.84 to 62.86 gCO2e/MJ, depending on the feedstock and production pathway. The lowest carbon intensity for biodiesel is achieved by using waste cooking oil as the feedstock and renewable methanol as the transesterification agent. The highest carbon intensity is associated with using soybean oil as the feedstock and fossil-based methanol as the transesterification agent. The lowest carbon intensity for renewable diesel is achieved by using waste cooking oil as the feedstock and renewable hydrogen as the hydrotreating agent. The highest carbon intensity is associated with using soybean oil as the feedstock and fossil-based hydrogen as the hydrotreating agent.

Oregon Prices and Incentives for Renewable Diesel and Biodiesel 

Oregon is one of the states that has adopted a Clean Fuels Program (CFP), which aims to reduce the carbon intensity of transportation fuels by 10% by 2025. The CFP creates a market for low-carbon fuels such as renewable diesel and biodiesel by requiring fuel suppliers to either blend them with petroleum diesel or buy credits from low-carbon fuel producers. The CFP also provides incentives for consumers to use low-carbon fuels by reducing their fuel taxes. 

According to the Oregon Department of Environmental Quality (DEQ), the average price of diesel in Oregon as of November 2021 was $3.87 per gallon. The average price of biodiesel blends ranged from $3.88 per gallon for B5 (5% biodiesel) to $4.01 per gallon for B20 (20% biodiesel). The average price of renewable diesel was $4.05 per gallon. As of July 2023 the price of renewable diesel (R99) in Oregon was 50 to 60 cents higher than biodiesel (B99). 

The DEQ also provides a Fuel Cost Calculator that allows consumers to compare the costs and benefits of different fuels based on their vehicle type, fuel efficiency, annual mileage, fuel price, carbon intensity, and tax rate. According to the calculator, using renewable diesel instead of petroleum diesel would save an average consumer $34 per year in fuel costs and reduce their carbon emissions by 1.6 metric tons per year. Using biodiesel instead of petroleum diesel would save an average consumer $12 per year in fuel costs and reduce their carbon emissions by 0.8 metric tons per year. 

Renewable diesel and biodiesel are both viable alternatives to petroleum diesel that can help reduce greenhouse gas emissions and support renewable energy sources. However, they also have some trade-offs in terms of cost, availability, performance, and emissions. Consumers should consider their vehicle type, driving habits, fuel preferences, and environmental goals when choosing between these fuels. Oregon offers some incentives and programs to encourage the use of low-carbon fuels such as renewable diesel and biodiesel, which can help consumers save money and reduce their carbon footprint.

Diesel Quality Matters When Filling Your Tank

There are different grades of diesel fuel or diesel quality just like gasoline, and they can have a big impact on your vehicle’s performance, efficiency, and longevity. Quality diesel offers substantial benefits for your hard-working trucks, even when price is a major factor.

Clean Diesel: A Boost for Your Engine and the Environment

High-quality fuel goes beyond just powering your engine, unlike standard diesel. Like TOP TIER gasoline, premium diesel has enhanced cleaning additives. As a result, you’ll see a range of benefits that directly impact your vehicle’s performance, efficiency, and even your wallet. Let’s take a look at clean diesel’s advantages.

  • Improved Performance: Clean fuel ignites readily, giving your engine a noticeable power boost and smoother operation.

  • Enhanced Fuel Economy: Every drop counts! Clean diesel allows you to travel farther on a single tank.

  • Reduced Emissions: Be eco-friendly – cleaner burning translates to less smoke and pollutants in the air.

  • Extended Engine Life: Protect your investment! High-quality diesel reduces wear and tear on your engine components, saving you money on repairs down the road.

Understanding Diesel Quality

Two key factors determine diesel quality: the cetane number and the sulfur content. The cetane number tells you how easily fuel ignites, like a spark plug’s rating. Higher cetane numbers mean smoother starts, less knocking, and better performance – essential for modern diesel engines that typically need 40 or higher cetane ratings. Sulfur, however, can damage emissions systems and engine components if too much is used as a lubricant. These days, sulfur content is capped at ultra-low levels (Ultra-Low Sulfur Diesel or ULSD), ensuring cleaner engines.

  • Cetane Number: This number indicates how easily fuel ignites. Higher cetane numbers mean smoother starts, less engine knocking, and better overall performance. Modern diesel engines typically require a 40 cetane rating.

  • Sulfur Content: Sulfur acts as a lubricant in diesel fuel, but excessive levels can harm emissions systems and engine components. Modern regulations limit sulfur content to ultra-low levels (Ultra-Low Sulfur Diesel or ULSD).

Beyond the Pump: The Long-Term Value of High-Quality Diesel

While price at the pump is important, don’t let it overshadow high-quality diesel’s long-term value. Clean fuel isn’t just about saving money; it’s about keeping your car healthy. Clean diesel unlocks a bunch of benefits: a smoother ride and more power, better fuel economy that lets you go farther on each tank, fewer emissions so you don’t have to worry about air pollution, and a longer engine life, so you don’t have to spend money on repairs. Do you want to feel the difference? The next step is to find a good diesel provider. Thanks to enhanced cleaning additives, many stations prioritize clean diesel. Discover how clean diesel can improve your vehicle’s performance, efficiency, and longevity by researching stations near you.

Imagine a scenario where cleaner diesel offered similar performance and reliability to regular diesel. What other factors might still prevent you from making the switch?

Portland Retail Fuel Price Variance

Fuel Market News

Fuel prices are up this week across the board as diesel and gas prices increased by over $0.20/gal. Rack averages in Portland jumped $0.24/gal for regular E10 gasoline, and $0.30/gal for B5 & B20 diesel. These price increases also hit the retail market, with prices up $0.13/gal on the AAA average. Crude oil is just above $60/barrel for WTI crude, up $2/barrel from the previous week. This is the highest increase in crude oil pricing we have seen in multiple weeks and is partially responsible for why prices jumped so significantly this week.

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 Above $60

OPEC+ Strategic Pause

Crude oil is trading just above $60, at a current price of $61.95/barrel. This is $2.52/barrel higher than the week prior. 

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 $61.95/barrel compared to $59.43/barrel last week and $72 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.

The Pros and Cons of Renewable Diesel in Your Diesel Truck 

 As the world continues to become more aware of sustainable alternatives, renewable biodiesel (otherwise known as R99) has emerged as a promising solution to reduce carbon emissions in the transportation sector. Diesel truck owners, for example, may wonder whether they can switch to renewable diesel and contribute to a greener future as the city of Portland will be enforcing new restrictions and limitations on carbon emissions. Here is more information on the feasibility of using renewable diesel in diesel trucks and looking at the benefits and possible challenges. By understanding the advantages and limitations, you can make an informed decision about integrating this renewable fuel into your trucking operations.

1. Understanding Renewable diesel:

Renewable diesel is a clean-burning alternative fuel derived from natural sources such as vegetable oils, animal fats, and recycled cooking oil. It is produced through a process called transesterification, where the oils or fats are chemically reacted with alcohol to separate the glycerin from the fatty acids, resulting in renewable diesel. This sustainable fuel can be used in diesel engines with little to no modifications, making it a viable option for diesel truck owners. 

 

2. Environmental Benefits of Renewable Diesel:

Renewable diesel (known as R99) has significant environmental benefits. Renewable diesel reduces greenhouse gas emissions, such as carbon dioxide, sulfur dioxide, and particulates matter, compared to traditional diesel. It has lower levels of harmful pollutants, contributing to improved air quality and reduced smog formation. Additionally, renewable diesel is biodegradable, non-toxic, and significantly minimizes net carbon dioxide emissions over its lifecycle, making it a valuable tool in mitigating climate change. 

 

3. Compatibility and Performance:

While renewable diesel is compatible for diesel engines as a drop in solution, its essential to consider any factors before switching. Renewable diesel has a slightly lower energy content than regular diesel, which can result in a slight decrease in fuel economy.

 

4. Availability and Infrastructure:

Is renewable diesel readily available? While renewable diesel is becoming more widespread, its availability may vary depending on your location.

Benefits of an Automatic Fuel Delivery Service

Automatic Fuel Delivery Provides Convenience.

Fuel delivery services take the hassle out of managing your fuel needs. You don’t have to check your fuel levels or schedule deliveries anymore. Fuel providers monitor your usage and deliver fuel before you run out.

 

Automatic Fuel Delivery Allows More Peace of Mind.

With automatic fuel delivery, you can rest assured knowing that you will always have the fuel you need to keep your business running smoothly. This is especially important during cold weather months.

Automatic Fuel Delivery Can Provide Potential Savings.

Automatic delivery is offered by many fuel providers at a discount. A run-out charge and other emergency fees may also save you money on fuel costs. It also saves money through the time and convenience that automatic fuel delivery offers by avoiding drivers having to go off of their route to sit and wait in line to fill up their tanks. This also provides less risk on potential fuel theft. There are a variety of ways directly, and indirectly that provide cost savings for your business’ bottom line.

 

Automatic Fuel Delivery Will Help With Environmental Benefits.

Automatic fuel delivery services (or on-site fueling) can help to reduce your environmental impact by reducing the number of fuel deliveries that need to be made. As a result, emissions can be reduced and traffic congestion can be reduced. With Portland’s Climate Action Plan and their roadmap to achieve 80% reduction in carbon emissions by 2050, with 40% reduction by 2030, reducing the number of stops and idle time on the roads will reduce this number significantly. If you consider adding renewable diesel to your tanks as a drop-in solution for your trucks, then you will continue to reduce your emission’s even further.
