Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
64 words

Claim 2
Dependent Claim
64 words
A lubricant composition comprising a major proportion of an oil of lubricating viscosity of grease prepared therefrom, and a minor effective proportion of a friction reducing additive consisting of C 8 to C 29 borated adducts of a hydrocarbyl mono- or diamine and mixtures thereof wherein said hydrocarbyl comprises a member selected from the group consisting of alkyl, alkenyl, alkylene cycloalkyl and mixtures thereof.
Claim 3
Dependent Claim

Claim 9
Dependent Claim
18 words
The composition of claims 1, 2 or 3 wherein said oil of lubricating viscosity is a snythetic oil.
Claim 10
Dependent Claim
22 words
The composition of claim 1, 2 or 3 wherein said oil of lubricating viscosity is a mixture of synthetic and mineral oils.
Claim 11
Dependent Claim
15 words
