Neste MY Renewable Diesel (formerly NExBTL) is a vegetable oil refining fuel production process commercialized by the Finnish oil and refining company Neste. Whether as an admixture or in its pure form, the fuel is able to supplement or partially replace conventional diesel without problems. Neste guarantees that every gallon sold meets ASTM D975 and EN 15940 specifications in compliance with OEM standards.[1]
Despite the former name BTL, the feedstock is vegetable oil and waste animal fats, not whole plants. However, fuel quality is equal to the synthetic Fischer-Tropsch BTL and GTL diesel fuels.
