On-Road Diesel Fuel
On-Road Diesel Fuel (as opposed to Off-Road Diesel Fuel) is used for vehicles and equipment that utilize public roadways. This includes anything from personal vehicles to tractor trailers to buses. On-Road Diesel fuel has the appropriate taxes added to the sale for use on the roads.
All of the diesel fuel that we sell, both on-road and off-road, is ultra low sulfur diesel fuel at 15ppm.
WHAT is ULTRA LOW SULFUR DIESEL FUEL (ULSD)?
- ULSD is diesel fuel with a maximum sulfur content of 15 ppm (parts per million) and is often referred to as S 15. S 15, S500, and S5000 are designations for diesel fuels that meet 15 ppm, 500 ppm, and 5,000 ppm maximum sulfur content, respectively.
- ULSD will be required for all 2007 and later model year on-road diesel engines.
