  • LUBRICANT ADDITIVES
    Publication number: 20250326981
    Abstract: This disclosure describes a gaseous-fueled, low-speed, or medium speed engine lubricating oil composition. The composition includes a major amount of base oil; and a lubricant additive having the following structure: where each R1 is independently a hydrocarbyl group having 10-400 carbons; X is an alkyl, aryl, or heteroaromatic group having 1 to 10 carbons; Y is nitrogen, oxygen, or sulfur; each R2 is independently a hydrocarbyl group having 1 to 9 carbons; Z is nitrogen, oxygen, or sulfur; and each R3 is independently a hydrogen or hydrocarbyl group having 1 to 9 carbons with one or more nitrogen, oxygen, or sulfur functionalization, wherein p is 1 to 3, n is 1 to 20 and m is 0 to 3.

  • Lubricating oil additive composition and method of making the same
    Patent number: 9029304
    Abstract: An oil-soluble lubricating oil additive composition comprising (a) at least 3.5 wt-% of at least one friction modifier selected from the group consisting of fatty acids, fatty acid amides, fatty acid esters, and alkane diols which have a melting point of greater than 30° C.; (b) at least 10 wt-% actives dispersant; and (c) a sufficient amount of surfactant to make said additive composition haze-, sediment-, and skin-free, provided that said additive composition contains at least 150 mm surfactant per kg of said lubricating oil additive composition.

  • GLYCEROL-CONTAINING FUNCTIONAL FLUID
    Publication number: 20120165235
    Abstract: A functional fluid comprising a major amount of an oil of lubricating viscosity, and greater than about 0.05 wt-% glycerol. A method of preparing a functional fluid comprising adding glycerol to a functional fluid, wherein the glycerol is not glycerol monooleate. A method of preparing an additive concentrate comprising adding glycerol to a diluent oil wherein the concentrate contains from about 1% to about 99% by weight of said diluent. A method of reducing friction comprising contacting a metal surface with a functional fluid comprising a major amount of an oil of lubricating viscosity and greater than about 0.05 wt-% glycerol.
