Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
94 words
A lubricant composition comprising a major proportion of an oil of lubricating viscosity or grease or solid lubricant prepared therefrom and a minor friction reducing proportion of an additive compound selected from borated adducts of N-ethoxylated amides having the following generalized structure: ##STR2## wherein R is hydrocarbyl containing 10-40 carbon atoms selected from alkyl, alkenyl, aralkyl or alkaryl, x and y are whole numbers from 1 to about 10 and where x and y may be the same or different with the proviso that x plus y must be at least 2 or more.
Claim 2
Dependent Claim
94 words
A lubricant composition comprising a major proportion of an oil of lubricating viscosity or grease or solid lubricant prepared therefrom and a minor friction reducing proportion of an additive compound selected from borated adducts of N-ethoxylated amides having the following generalized structure: ##STR2## wherein R is hydrocarbyl containing 10-40 carbon atoms selected from alkyl, alkenyl, aralkyl or alkaryl, x and y are whole numbers from 1 to about 10 and where x and y may be the same or different with the proviso that x plus y must be at least 2 or more.
Claim 3
Dependent Claim
13 words
The composition of claim 1 wherein the additive compound is borated bis(2-hydroxyethyl) oleamide.
Claim 4
Dependent Claim
15 words
The composition of claim 1 wherein the additive compound is borated polyoxyethylene (5) hydrogenated tallowamide.
Claim 5
Dependent Claim
14 words
The composition of claim 1 wherein the additive compound is borated polyoxyethylene (5) oleamide.
Claim 6
Dependent Claim
18 words
The composition of claim 1 having from about 0.1 to about 10 wt. % of the additive compound.
Claim 7
Dependent Claim
18 words
The composition of claim 5 having from about 0.25 to about 4 wt. % of the additive compound.
Claim 8
Dependent Claim
20 words
The composition of claim 1 wherein the oil of lubricating viscosity is a mineral or synthetic oil or mixtures thereof.
Claim 9
Dependent Claim
12 words
The composition of claim 7 wherein said oil is a mineral oil.
Claim 10
Dependent Claim
12 words
The composition of claim 7 wherein said oil is a synthetic oil.
Claim 11
Dependent Claim
18 words
The composition of claim 1 comprising a grease or solid lubricant prepared from an oil of lubricating viscosity.
Claim 12
Dependent Claim
48 words
A method for reducing fuel consumption in an internal combustion engine by treating the moving surfaces thereof with a composition comprising a major amount of an oil of lubricating viscosity containing a minor friction reducing or fuel reducing amount of an additive compound as described in claim 1.
