Sulfur in Diesel: ULSD, Biodiesel and More

Sulfur is a staple in all diesel products available, but what does it mean for you? Is it good for your vehicle? Let’s take a look at the different levels of sulfur in diesel products and how it affects your equipment.

What is Ultra-Low Sulfur Diesel?

Since 2010, U.S. regulations require all pumps to dispense ultra-low sulfur diesel (ULSD) instead of low- sulfur diesel (LSD). Along with this, all vehicles made after 2007 are only compatible with ULSD due to the reduced sulfur content. ULSD contains 97% less sulfur compared to LSD, which makes the diesel safe to use with newer emission control mechanisms in modern vehicles. Higher sulfur content is harmful to these systems. Sulfur is not only bad for engines, but also is one of the leading pollutants in diesel exhaust.


Is Biodiesel Ultra-Low Sulfur?

Biodiesel is a fuel made from plant or animal products and results in less pollution than traditional diesel. It must meet the same ULSD standard for total sulfur to comply with EPA regulations. Therefore, biodiesel generally it contains even less sulfur than ultra-low sulfur diesel. While there are small differences between biodiesel and traditional diesel, they do not pose a danger to your engine when you go to the pump. In Oregon, all diesel sold at the pump is at least 5 percent biodiesel (also known as B5).

Is Off-Road Diesel Ultra-Low Sulfur?

Off-road diesel, or dyed diesel, is also ultra-low sulfur. It still complies with the EPA environmental requirements and will not damage engines. However, do not fuel your highway vehicles with it, as it can only be used with equipment that will not be driven on public roads. This equipment can include generators, construction equipment or other diesel-powered machines. To learn more about off-road diesel, check out our blog about clear and red-dyed diesel.

Jubitz is Leading the Way with Biodiesel Blends

Biodiesel Blends

Are you looking to reduce your company’s carbon footprint? A great first step is to research the fuel you’re using. At Jubitz, we continue to raise the bar with our biodiesel blends. Oregon law requires that all diesel sold must be at least 5 percent biodiesel (referred to as B5). Jubitz’s commitment to the environment means that most of the diesel we sell in Oregon is at least 10 percent biodiesel (B10)! We can even mix custom biodiesel blends up to B99 on demand.

How does it effect the environment?

  1. Reduce the use of fossil fuels: By incorporating renewable sources like soy, cooking oil, and other organic materials, biodiesel blends decrease our reliance on finite fossil fuels.
  2. Utilize renewable fuels: They harness the power of renewable fuels, contributing to sustainability efforts and reducing environmental impact.
  3. Improve air quality: These blends aid in reducing greenhouse gas emissions, thus improving air quality and promoting healthier communities.
  4. Minimize waste: By repurposing materials like cooking oil into biodiesel, we help minimize waste and promote a circular economy.
  5. Improve water quality: It reduces the release of fat, oil, and grease into sewers, thus enhancing water quality and protecting ecosystems.

What are the benefits for your diesel engines?

  1. Improved fuel lubricity and engine life: They enhance fuel lubricity, thereby extending the life of diesel engines and reducing maintenance costs.
  2. Compatibility with existing diesel engines: It can be seamlessly integrated into existing diesel engines, offering a sustainable fuel option without requiring engine modifications.
  3. Comparable performance: It offers similar horsepower, torque, and fuel mileage to conventional diesel, ensuring reliable performance without compromising efficiency.
  4. Reduced carbon emissions: By decreasing carbon emissions, biodiesel blends contribute to mitigating climate change and promoting environmental stewardship.
