Claims19
A method of lubricating an internal combustion engine comprising supplying to the internal combustion engine a lubricating composition comprising an oil of lubricating viscosity and a nitrile compound, wherein the nitrile compound is represented by formula (1a):
- wherein
- X is a linear or branched hydrocarbylene group, or a heteroatom-containing hydrocarbylene group;
- R is a linear or branched hydrocarbyl group, an alkoxy group or an aryloxy group;
- and
- R′ is hydrogen, or a linear or branched hydrocarbyl group, an alkoxy group or an aryloxy group.
A method of lubricating an internal combustion engine comprising supplying to the internal combustion engine a lubricating composition comprising an oil of lubricating viscosity and a nitrile compound, wherein the nitrile compound is represented by formula (1c):
- wherein
- X is a linear or branched hydrocarbylene group, or a heteroatom-containing hydrocarbylene group;
- R is a linear or branched hydrocarbyl group.
A method of lubricating an internal combustion engine comprising supplying to the internal combustion engine a lubricating composition comprising an oil of lubricating viscosity and a nitrile compound, wherein the nitrile compound is represented by formula (1d):
- wherein
- X is a linear or branched hydrocarbylene group, or a heteroatom-containing hydrocarbylene group;
- and
- R is a linear or branched hydrocarbyl group, alkoxy group or aryloxy group.
