Patent ID: 7482312

Claim:
An automotive racing oil comprising: base oil comprising polyalphaolefin and racing oil components effective to produce automotive racing oil properties comprising a kinematic viscosity of from about 3.2 centistokes (cSt) to about 25 cSt at 100° C., and a coefficient of friction of about 0.065 or less at 180° C.; the racing oil components comprising: one or more oil-soluble molybdenum compound selected from the group consisting of molybdenum dithiocarbamates and molybdenum dithiophosphates, the automotive racing oil having a molybdenum concentration of more than 360 ppm, as measured by X-ray fluorescence; one or more anti-wear additive comprising zinc selected from the group consisting of zinc dihydrocarbyl dithiophosphates and zinc dihydrocarbyl dithiocarbamates, the automotive racing oil having a zinc concentration of about 1400 ppm or more, as measured by X-ray fluorescence; and, a quantity of a combination of esters maintaining the racing oil components in solution in the base oil, the combination of esters comprising one or more multiester(s) and one or more polyol monoester(s), wherein the one or more multiester(s) are selected from the group consisting of tricarboxylic acid triesters.
