摘要： A method for preventing or reducing engine knock or pre-ignition in a high compression spark ignition engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition that contains at least one branched hydrocarbon having at least about 25% of the carbons in the form of methyl groups, or at least one polyol ester of at least one branched mono-carboxylic acid. A lubricating engine oil having a composition that contains at least one branched hydrocarbon having at least about 25% of the carbons in the form of methyl groups, or at least one polyol ester of at least one branched mono-carboxylic acid. The lubricating engine oils are useful as passenger vehicle engine oil (PVEO) products.

摘要： According to the present disclosure, there is provided a high-temperature lubricant composition. The composition has an amount of an ester. The ester exhibits a kinematic viscosity at 100 °C of 1 to 4 centistokes and a kinematic viscosity ratio at 150°C/100°C of 0.6 or higher. The composition is at a temperature of 100 °C to 150 °C. There is also another lubricating composition having the ester and a polymeric viscosity modifier. There are also methods for using the lubricating compositions in the crankcase of an engine.

摘要： The present invention is directed to a method for controlling soot induced viscosity increase in diesel engines, by using as the diesel engine lubricant an oil formulation comprising a base oil containing about 10 to 80 wt% GTL base stock and/or base oil and/or hydrodewaxed or hydroisomerized/-catalytic (or solvent) dewaxed base stock and/or base oil in combination with 20 to 90 wt% conventional Group I and/or Group II petroleum derived base oil, said base oil being further combined with a polymeric viscosity modifier, and to the lubricating oil which effects such control over soot induced viscosity increase.

摘要： A lubricating composition is provided comprising a polyol ester which is the reaction product of a neopolyol with linear or branched monocarboxylic acids and mixtures thereof having from 1 to about 25 carbon atoms and a natural or GTL oil of lubricating viscosity and mixtures thereof and wherein the weight ratio of the ester to oil will be sufficient to provide a composition having a viscosity less than the individual viscosities of the ester and oil.
