摘要:
In its broadest concept, the present invention relates to an improved gear oil comprising: a) a base oil having a viscosity range of 4 to 32 cSt at 100° C.; b) a maximum level of hydrocarbyl polysulfide with a minimum level of active S species; c) a dihydrocarbyl dithiophosphate ester or salt; and d) a dihydrocarbyl (mono)thiophosphate amine salt, essentially free of phosphite.
摘要:
The present disclosure relates to a lubricant composition comprising a first phosphorus compound, a second phosphorus compound, and a third phosphorus compound, wherein the first phosphorus compound is present in the lubricant composition in an amount to provide between about 120 and 350 ppm phosphorus. The lubricant composition may provide robust anti-wear and reduced pitting.

摘要:
A fluid composition for all-wheel drive wet multi-disk brakes and/or differentials having improved characteristics, additive concentrates for all-wheel drive vehicles and methods for improving fluid characteristics for all-wheel drive vehicles. The fluid composition is a base oil having therein an extreme pressure/antiwear additive package and a limited slip/antiwear additive package. The additive composition is substantially devoid of dithiophosphate components and has from about 1000 to about 2000 ppm phosphorous from phosphorous-containing components based on a total weight of the fluid composition.
