A lubricant formulation for an electric or hybrid vehicle includes a base oil, or a blend thereof, one or more additives, and a molybdenum amine complex, such as diisotridecylamine molybdate, are provided. Lubricant formulations can be characterized by one of: improving electric motor protection when a volatage is applied to an electrode in the presence of a formulation comprising the diisotridecylamine molybdate additive as compared to a fluid lacking the diisotridecylamine molybdate additive; maintaining the electrical resistance slope of a formulation comprising the diisotridecylamine molybdate additive as compared to a fluid lacking the diisotridecylamine molybdate additive; the formulation forming a protective film on copper surfaces; a change in color of the formulation indicating contact load, temperature, time, or viscosity change.

Disclosed herein are improved lubricating compositions effective to prevent or reduce low speed pre-ignition in an engine, as well as to prevent or reduce corrosion of engine components. The lubricating compositions include a base oil combined with a calcium chelate complex, optionally in further combination with additional additives.

A reactive composition comprising:

(A) a glycerol monoester; (B) an acid amide in which the chain length of the acid portion comprising the amide contains about 8 to about 28 carbon atoms; and (C) a molybdenum compound in which the oxidation state of the molybdenum is +6; and a product prepared by reacting the reactive composition, including a product in the form of a composition which is useful as a friction modifier; and a lubricating composition comprising a lubricant in admixture with the friction modifier.

The purpose of the present invention is to provide organometallic salt compositions that are useful as lubricant additives and/or in lubricant additive compositions to reduce friction and wear, and also have improved solubility in all four types of hydrocarbon base oils (Groups I-IV) at a variety of concentrations and under a variety of conditions. The organometallic salt composition is derived from at least one long chain monocarboxylic acid and a single metal in combination with at least one short or medium branched-chain monocarboxylic acid. The compositions are particularly useful in combination with activated complexes comprising a first metal component, a second metal component and particles comprising the first metal component.

A method for improving corrosion resistance, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition comprising a lubricating oil base stock as a major component, and at least one friction modifier having an elemental composition comprising one or more of nitrogen (N), oxygen (O), and phosphorus (P), as a minor component. The formulated oil has a corrosion factor, based on the elemental composition of the at least one friction modifier, of less than 500, as determined by the formula:

12900(N wt %)+3967(O wt %)8524(P wt %)250=corrosion factor.

The lubricating oils are useful as passenger vehicle engine oils (PVEO) and commercial vehicle engine oils (CVEO).
