Disclosed is a composition of continuously variable transmission oil for improving fuel efficiency and endurance performance. Provided herein is a novel composition of continuously variable transmission oil that can improve fuel efficiency through reduction of fluid resistance by decreasing viscosity at a low temperature, and can enhance endurance performance of the transmission by increasing the viscosity at a high temperature. Provided herein is a continuously variable transmission oil composition containing a predetermined amount of olefin amide comb PMA as a viscosity adjusting agent in a base oil having a pour point of 40 C. or less, in addition to additives.

Provided herein are grease compositions comprising at least one estolide compound of formula:

##STR00001##

in which n is an integer equal to or greater than 0; m is an integer equal to or greater than 2; R.sub.1, independently for each occurrence, is selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; R.sub.2 is selected from hydrogen and optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; and R.sub.3 and R.sub.4, independently for each occurrence, are selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched. Also provided are methods of making estolide-based grease products.

Sulfurized calcium phenate detergents having a reduced unsulfurized alkyl-substituted phenol content are made by: (A) providing, made from an unsulfurized alkyl-substituted phenol, a sulfurized calcium phenate detergent that, optionally, may have been further reacted with carbon dioxide; (B) adding to the detergent from 1 to 100 mass %, based on the mass of the detergent, of an organic solvent that has a boiling point of above 100 C. and below the boiling point of the unsulfurized alkyl-substituted phenol; and (C) removing the organic solvent from the detergent thereby to reduce the unsulfurized alkyl-substituted phenol content.
