Abstract
Abstract Disclosed are fuel compositions including alcohol-extended fuels containing friction-reducing, anti-corrosion and detergent amounts of at least one fuel soluble glycine derivative of the formula: RNHCH.sub.2 X wherein R is a hydrocarbyl group having 6 to 18 carbons and X is ##STR1## wherein R 1 is lower alkyl having 1 to 5 carbon atoms; R 2 is alkylene having 1 to 5 carbon atoms; R 3 is an alkylamino or alkylpolyamino group having 1 to 5 carbon atoms.
