What are P-Series fuel?
P-Series fuel is a blend of natural gas liquids (pentanes plus), ethanol, and the biomass-derived co-solvent methyltetrahydrofuran (MeTHF), all of which are domestically produced, renewable and nonpetroleum ingredients. It can be use as a substitute for gas or blended in any proportion with gasoline and used in a FFV fuel tank. P-Series fuels were officially designated as an alternative fuel by the U.S. Department of Energy (DOE) in 1999. However, it is not widely produced to used in vehicles yet.
