A lubricant composition comprising a major proportion of a lubricating oil or grease therefrom and a friction reducing amount of a borated product made by borating a mixture of (1) a hydrocarbyl vicinal diol or a mixture of hydrocarbyl vicinal diols and (2) a long chain alcohol or a mixture of long chain alcohols.
Claim 2
Dependent Claim
54 words
A lubricant composition comprising a major proportion of a lubricating oil or grease therefrom and a friction reducing amount of a borated product made by borating a mixture of (1) a hydrocarbyl vicinal diol or a mixture of hydrocarbyl vicinal diols and (2) a long chain alcohol or a mixture of long chain alcohols.
