With Renewable Diesel, we are providing the fuel Californians are asking for. Better for engines due to its higher cetane levels, Renewable Diesel also reduces SO2 and NOx emissions as well as life-cycle carbon. We continue to provide the highest quality fuels to our customers.

What are Renewable Fuels?

Renewable fuels are made from renewable resources – used cooking oils, fats, greases, vegetable oils, grains and sugars – that can be replenished. Examples include renewable diesel, ethanol, and biodiesel.

Types of Diesel:
Renewable Diesel v. Biodiesel v. CARB Diesel*

Renewable Diesel is a non-petroleum hydrocarbon fuel, produced from renewable feedstocks – fats and vegetable oils – by refining them through a hydrotreater. It is a very high-quality, fully refined diesel that is physically and chemically very similar to conventional diesel. It can be blended with conventional diesel or used as a drop-in fuel (conforming with ASTM D975), a complete replacement for conventional diesel.

Biodiesel is a non-hydrocarbon fuel produced from renewable feedstocks – fats and vegetable oils – by reacting them with methanol. It cannot be used as a replacement for conventional diesel, as it must be blended with conventional or renewable diesel and requires special handling.

CARB is a conventional, petroleum-based hydrocarbon fuel produced from fossil fuels, a nonrenewable natural resource.

  • Renewable diesel, biodiesel and CARB diesel are all approved for use in California by the California Air Resources Board (CARB).
