An engine oil comprising a major amount of a base oil and a minor amount of an additive package, wherein the additive package comprises at least one friction modifier represented by the formula:
wherein R is selected from a hydrocarbyl group having 12 to 28 carbon atoms, a heteroatom containing hydrocarbyl having 12 to 32 carbon atoms, or a group represented by the formula:
wherein R
1
and R
2
are independently selected from hydrocarbyl carbonyl moieties having 12 to 28 carbon atoms, or R
1
and R
2
form a hydrocarbon dicarbonyl containing ring with 12 to 32 carbon atoms, and R
3
and R
4
are independently selected from alkyl groups having 1 to 18 carbon atoms. Methods of using the engine oil to improve thin film and/or boundary layer friction in an engine are also provided.
