Using Shell Diesel in your vehicle means that you will benefit from putting dependable quality fuel in your vehicle. Shell Ultra Low Sulfur Diesel (ULSD) can be used in all on-highway diesel engines – both traditional and new ultra clean engines -- and is designed to meet all government regulations.
Driving a diesel powered vehicle doesn’t mean that have to you miss out on the benefits of quality Shell fuels. Shell Diesel (ULSD) can be used with confidence in all model-year vehicles and will also reduce environmental emissions compared to traditional low sulfur diesel fuel.
Look for the Ultra Low Sulfur Diesel (ULSD) Label
Effective December 1, 2010, all diesel sold for on-highway use (e.g. service stations, truckstops) must meet ULSD quality. Diesel sold for off-highway use may contain higher sulfur levels in some parts of the US.
If you purchase a diesel-powered vehicle that requires ULSD, you must use ULSD. Using non-ULSD fuel can harm the environment as well as damage your vehicle’s emission control system, which could lead to costly repairs. If you are unsure whether your vehicle requires ULSD, please check your owner’s manual.

Q1. What is ULSD?
A1. Ultra Low Sulfur Diesel (ULSD) is a cleaner burning diesel fuel than the traditional Low Sulfur Diesel (LSD). The primary difference between the two types of diesel fuel is the much lower sulfur content in the ULSD fuel compared to. the LSD fuel. ULSD has a maximum of 15 ppm (parts per million) sulfur content whereas the LSD can have up to 500 ppm sulfur content.
Q2. How does ULSD affect the air quality?
A2. ULSD fuel is designed for use with cleaner technology diesel engines and vehicles with advanced emissions control devices. The result is significantly improved air quality. Annual emission reductions will be equivalent to removing the pollution from more than 90% of today’s diesel trucks and buses, when the current heavy-duty vehicle fleet has been completely replaced by 2030.
Q3. Which model year vehicles are required to use ULSD?
A3. All light-duty passenger diesel-powered vehicles built in 2007 or later are required to use ULSD fuel, but some medium-duty and heavy-duty diesel-powered model year 2007 vehicles are built with 2006 model year engines that are not equipped with sulfur-sensitive advanced emission control systems. Vehicles that require ULSD fuel have specific labels on the dashboard and near the fuel inlet indicating that they must be fueled with ULSD fuel. Also check the owner’s manual for your vehicle manufacturer’s recommendation.
Q4. May I continue to purchase Low Sulfur Diesel fuel if I prefer to use it in my older vehicle?
A4. Effective December 1, 2010, all diesel sold for on-highway use (e.g. service stations, truckstops) must meet ULSD quality. Diesel sold for off-highway use may contain higher sulfur levels in some parts of the US. Owners of 2007 and later model year diesel-powered highway vehicles must refuel only with ULSD fuel. Owners of 2006 and earlier model year diesel-powered engines and vehicles can refuel with ULSD without concern.
Q5. Can non-Ultra Low Sulfur Diesel fuel be burned without operational problems in 2007 model year and later cars and trucks?
A5. Diesel-powered engines for 2007 and later model year highway vehicles are designed to operate only with ULSD fuel. Use of any other fuel can reduce the efficiency and durability of engines, permanently damage advanced emissions control systems, reduce fuel economy and possibly prevent the vehicles from running at all. Manufacturer warranties are likely to be voided by the use of the wrong fuel.
Q6. How do I know which pump is dispensing ULSD fuel?
A6. Federal regulations require that all fuel pumps specify the type of fuel being dispensed. See below for a sample of a ULSD sticker that can be found at diesel dispensers.
Similar vehicle instrument panel and fuel inlet/fill cap labeling is mandated for 2007 and later model year engines and vehicles that require ULSD fuel. Consumers are advised to check the pump and vehicle labels to ensure they are refueling with the proper diesel fuel consistent with their vehicle warranty.
Q7. How does ULSD fuel affect the power and fuel economy of existing diesel cars, trucks and non-road engines and equipment?
A7. Under typical operating conditions, there should be no noticeable impact on overall power using ULSD fuel. Fuel economy may be reduced slightly because the process that removes sulfur also can reduce the energy content of the fuel.
Q8. Where can I get additional information on ULSD and compliance requirements?
A8. For compliance information, visit the U.S. EPA Clean Diesel website: http://www.epa.gov/otaq/diesel/index.htm
Biodiesel is a type of diesel fuel derived from vegetable oils and/or animal fats that contains carbon, hydrogen and oxygen. When biodiesel is blended with regular diesel, the blend is referenced by the letter “B” and the percentage of biodiesel it contains, such as B5 biodiesel blend (5% biodiesel, 95% diesel).
