What happened to petroleum #2 diesel?

Over the last few years, the California Air Resources Board began phasing out petroleum-based diesel through a variety of policies designed to accelerate the transition to renewable diesel fuels (labeled R99 at the pump).

Biodiesel: This fuel is made from a mix of modified vegetable oils and blended with petroleum fuel, typically labeled B5 through B20, (percentage of biodiesel to petroleum based diesel). Biodiesel typically has a higher cetane number than petroleum products, meaning it ignites quicker. The upshot is improved engine performance, but it is important to note that biodiesel also has a lower energy density. This can result in reduced fuel mileage. Most major truck stops offer biodiesel as a cost saving alternative. The greatest concerns over using biodiesel are inconsistent quality and that is has a different chemical composition compared to other diesel fuels. Please consult your owners manual to determine what percentage of biodiesel can safely be used in your vehicle.

Renewable Diesel: On the other hand, renewable offers fuel performance that is similar to conventional petroleum diesel, but the end product is more expensive to produce when compared to biodiesel. Renewable diesel is manufactured from organic sources like waste animal fats, and even microalgae. The process used to make renewable is similar to petroleum diesel, which makes it chemically identical. It shares similar energy density and cetane numbers, making it an excellent “drop-in” substitute for petroleum based products.

The next time you fill up your diesel tank, read the label on the pump to verify that the fuel meets the requirements outlined in your owner’s manual.
