Claims16
A composition comprising a complex prepared by reacting a borated fatty acid ester of glycerol or mixtures thereof and an oil soluble alkyl or alkenyl succinimide at 25.degree. C. to 200.degree. C. wherein the wt% ratio of succinimide to borated fatty acid ester of glycerol to form the complex is in the range of 0.5:1 to 3:1.
A lubricating oil composition comprising a major amount of an oil of lubricating viscosity and an effective amount to reduce friction of a complex prepared by reacting:
- (a) a borated fatty acid ester of glycerol or mixtures thereof;
- and
- an oil soluble alkyl or alkenyl succinimide at 25.degree. C. to 200.degree. C. wherein the wt% ratio of succinimide to borated fatty acid ester of glycerol to form the complex is in the range of 0.5:1 to 3:1.
A lubricating oil concentrate comprising 10% to 90% by weight of a lubricating oil and from about 90% to about 10% by weight of a complex prepared by reacting:
- (a) a borated fatty acid ester of glycerol or mixture thereof;
- and
- (b) an oil soluble alkyl or alkenyl succinimide at 25.degree. C. to 200.degree. C. wherein the wt% ratio of succinimide to borated fatty acid ester of glycerol to form the complex is in the range of 0.5:1 to 3:1.
