The present patent application relates to a method for reducing wear and tear on mechanical parts that are in contact with each other in an internal combustion engine by using a lubricating composition comprising:

Lubricating composition for reducing wear and tear on dlc parts used in internal combustion engines

A borate ester represented by the following formula:  where Ris a hydrocarbon chain, Rand Rare independently either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5.

Less corrosive organoboron compounds as lubricant additives

A composition of matter represented by the following formula: where Ris an unsaturated or branched hydrocarbon chain, Ris either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5, when used in a lubricating composition, being effective for friction and wear reduction, while providing improved protection against copper and lead corrosion in an engine.

Less corrosive organic compounds as lubricant additives

A molybdate ester represented by the following formula: where Ris a hydrocarbon chain, Ris either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5, is effective when used in a lubricating composition in an amount sufficient to provide about 50-5000 ppm of molybdenum, with respect to friction and wear reduction, while providing improved protection against copper and lead corrosion.

Less corrosive organomolybdenum compounds as lubricant additives

The present invention relates to lubricating compositions comprising a compound of Formula I: wherein R-Rand R-Rare independently selected from the group consisting of hydrocarbyl groups and hydrocarbyl groups containing heteroatoms, such that the total carbon atoms from counterions Qand Qis from 8 to 76, and molybdate anion (Y) is a binuclear sulfur-containing dianion selected from the group consisting of [MoSO], [MoSO], [MoS], and mixtures thereof, and are present in the lubricating composition in an amount sufficient to provide about 100-15,000 ppm molybdenum.

Quaternary ammonium sulfur-containing binuclear molybdate salts as lubricant additives

The present invention relates to a compound of the Formula I: and a lubricating composition containing and a method for preparing the same. In Formula I, R-Rand R-Rare independently selected from the group consisting of hydrogen, hydrocarbyl groups and hydrocarbyl groups containing heteroatoms, such that the total carbon atoms from Qand Qis from 6 to 166 carbon atoms, and molybdate anion (Y) is a binuclear sulfur-containing dianion selected from the group consisting of [MoSO], [MoSO], and [MoS].
