A lubricating composition comprising an oil of lubricating viscosity, 1 to 1000 parts per million by weight of titanium in the form of an oil-soluble titanium-containing material, and at least one additional lubricant additive provides beneficial effects on properties such as deposit control, oxidation, and filterability in engine oils.

Titanium and molybdenum compounds and complexes as additives in lubricants

A quaternary ammonium salt detergent made from the reaction product of the reaction of: (a) polyalkene-substituted amine having at least one tertiary amino group; and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen and the use of such quaternary ammonium salt detergents in a fuel composition to reduce intake valve deposits.

Quaternary ammonium salt of a polyalkene-substituted amine compound

A lubricant comprising (a) an oil of lubricating viscosity; (b) a polyether of number average molecular weight 1000 to 10,000; said polyether comprising alkylene oxide monomer units, where the alkylene group contains 3 to 6 carbon atoms, and ethylene oxide monomer units; and (c) one or more anti-foam agents, where the lubricant has a sulfated ash content of less than about 0.7 percent, is useful for lubricating a stationary gas engine where the engine drives a compressor and where both the engine and the compressor are lubricated with the same lubricant.

Engine lubricants containing a polyether

A sump-lubricated, spark-ignited engine is lubricated by supplying thereto a lubricant which comprises (a) an oil of lubricating viscosity; (b) a polyether; and (c) a metal-containing detergent. The lubricant has a total phosphorus content of less than 0.075 percent by weight.

A low-sulfur, low-phosphorus composition comprising an oil of lubricating viscosity; a substantially nitrogen-free sufurized olefin antiwear agent; a nitrogen-containing dispersant; and an overbased detergent selected from the group consisting of salixarates, saligenins, salicylates, and glyoxylates; containing less than about 0.1 percent by weight phosphorus, less than about 0.5 percent by weight sulfur, and having less than about 1.2% sulfated ash, is useful for lubricating a diesel engine, exhibiting good antiwear performance.

Diesel lubricant low in sulfur and phosphorus

The present invention relates to the use of a RAFT polymer as an antiwear agent in a lubricant. The lubricant may be useful in a number of mechanical devices.

Antiwear polymer and lubricating composition thereof

A fuel additive concentrate comprises a friction modifier selected from the group consisting of an alkoxylated fatty amine, a fatty acid or derivative thereof, and mixture thereof; an alcohol; and a compatibilizer selected from the group consisting of a low molecular weight carboxylic acid or anhydride or derivative there of, glycol ether, alkylated phenol, and a mixtures thereof wherein the fuel additive concentrate remains fluid at &#x2212;80 C or lower wherein the solvent has enough aromatic content to permit the fuel additive concentrate to be a fluid at minus 80 C. A fuel composition comprises fuel and the fuel additive concentrate. A method of operating a gasoline internal combustion engine comprises fueling the engine with the fuel composition and is effective in reducing fuel consumption.

Fuel additive concentrate composition and fuel composition and method thereof

The disclosed invention relates to polymers with heterocyclic-containing groups, and to concentrates and lubricating oil compositions containing the polymers.

Polymers with pendant heterocyclic-containing groups and lubricating oil compositions containing same

Titanium compounds and complexes as additives in lubricants

Formulations using tartaric compounds of the present invention in a low sulfur, low ash and low phosphorous lubricant lower wear, and friction and improves fuel economy.

Tartaric acid derivatives as fuel economy improvers and antiwear agents in crankcase oils and preparations thereof

Tartaric acid derivatives in fuel compositions

A quaternary ammonium salt detergent made from the reaction product of the reaction of: (a) Mannich reaction product having a tertiary amino group, said Mannich reaction product being prepared from the reaction of a hydrocarbyl-substituted phenol, an aldehyde, and amine; and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen and the use of such quaternary ammonium salt detergents in a fuel composition to reduce intake valve deposits.

Quaternary ammonium salt of a mannich compound

The use of alkoxylates and nitrogen containing detergents in a fuel additive composition to prevent intake valve sticking and reduce intake valve deposits.

Use of fatty acid alkoxylates as a method to remedy engine intake valve sticking
