Renewable diesel and blends

There are no separate quality requirements for renewable diesel at the federal level. At the state level, the approach generally taken is to require that renewable diesel (in neat or blended form) meet all of the quality parameters and limits specified by the relevant fossil diesel specification, namely ASTM D975 “Standard Specification for Diesel Engine Fuel.”

This approach allows renewable diesel to be treated similarly to conventional diesel fuel in terms of meeting quality requirements and being compatible with existing diesel engine technology and infrastructure. By aligning with the established diesel fuel specifications, renewable diesel can seamlessly integrate into existing diesel fuel supply chains, and be used in diesel engines without the need for mod
