{{short description|Fuel family}} '''P-series fuels''' are a family of [[renewable fuels|renewable]], non-petroleum, liquid fuels that can substitute for [[gasoline]]. The blend of [[methyl tetrahydrofuran]] (MTHF), [[ethanol]], and [[hydrocarbon]] constitute the P-series fuel. These fuels are clear, [[Octane rating|high-octane]] alternative fuels that can be used in flexible fuel vehicles. It addresses three problems: the need for non-petroleum energy sources, solid waste management, and affordability. The feedstock is not incinerated, but chemically digested, so there is no combustion with the accompanying toxic air emissions.
