  • HYDROCARBON COMPOSITIONS USEFUL AS LUBRICANTS FOR IMPROVED OXIDATION STABILITY
    Publication number: 20230132628
    Abstract: Provided herein are hydrocarbon compositions suitable for use as a lubricant comprising sulfur between about 30 ppm to about 220 ppm, and aromatics between about 0.2 wt. % to about 3 wt. %. The present hydrocarbon compositions comprise a blend of one or more base stocks and a high-sulfur containing material and can demonstrate an improved oxidation performance as a lubricant in weighted piston deposit merits and/or by viscosity increase.
