(A) a friction modifier component selected from one or more compounds of the Formulae I-III:

wherein R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl having about 8 to about 22 carbon atoms and R 1 is hydrogen, a hydrocarbyl having from about 1 to about 8 carbon atoms, or a C 1 -C 8 hydrocarbyl group containing one or more heteroatoms;

wherein R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl having about 8 to about 22 carbon atoms and R 2 and R 3 are independently selected from hydrogen, C 1 -C 18 hydrocarbyl groups, and C 1 -C 18 hydrocarbyl groups containing one or more heteroatoms; and

wherein R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl having about 8 to about 22 carbon atoms; and X is an alkali metal, alkaline earth metal, or ammonium cation and n is the valence of cation X; and
(B) at least 0.1 wt % of at least one metal-containing detergent; and
wherein the engine oil composition is adapted for use as a crankcase engine oil lubricant suitable for lubrication of at least pistons, rings, cylinders, bearings and crankshafts of an engine crankcase, the engine oil composition has a phosphorus content of 50-1000 ppm and the engine oil composition contains 0.1-2.0 wt. % of the friction modifier component (A), based on a total weight of the engine oil composition.

2. The engine oil composition of claim 1 , wherein the additive package comprises at least one compound of the formula I.

3. The engine oil composition of claim 1 , wherein the additive package comprises at least one compound of the formula II.

4. The engine oil composition of claim 1 , wherein the additive package comprises at least one salt of the formula III.

5. The engine oil composition of claim 1 , wherein the additive package comprises at least two different compounds independently selected from compounds of the formulae I-III.

6. The engine oil composition of claim 1 , wherein R has from about 10 to about 20 carbon atoms.

7. The engine oil composition of claim 1 , wherein R has from about 12 to about 18 carbon atoms.

8. The engine oil composition of claim 1 , wherein R 1 is hydrocarbyl group having from about 1 to about 8 carbon atoms.

13. The engine oil composition of claim 1 , wherein the additive package further comprises at least one additive selected from the group consisting of antioxidants, antifoam agents, molybdenum-containing compounds, titanium-containing compounds, phosphorus-containing compounds, viscosity index improvers, pour point depressants, and diluent oils.

14. The engine oil composition of claim 1 , wherein the at least one detergent comprises two or more detergents.

15. The engine oil composition of claim 14 , wherein a first detergent has a total base number of 40 to 450 and a second detergent has a total base number of up to 80.
