  • 权利要求: What is claimed is:1. A non-turbid lubricating oil blend having a high viscosity index and exhibiting a high degree of detergency consisting essentially of a blend of a mineral oil base stockhaving combined therein about 0.05% to about 10.0% by weight of a copolymer of a fumarate ester containing from about 8 to 18 carbon atoms in the ester portion thereof and vinyl acetate, from about 0.2% to about 3.0% by weight of a metal salt of an alkylated phenol as a detergent inhibitor, and from about 0.01% to about 1.0% by weight of a compatibility improver of the class consisting of diethylene glycol monoethyl ether, methoxy tri-glycol, and dimethoxy tetraethylene glycol.2. A non-turbid lubricating oil blend having a high viscosity index and exhibiting a high degree of detergency consisting essentially of a mineral oil base stock having combined therein about 0.1% to about 2.0% by weight of a copolymer of a fumarate ester containing from 10 to 16 carbon atoms in the ester portion thereof and vinyl acetate, from about 0.08% to about 2.0% by weight of a metal salt of an alkylated phenol as a detergent inhibitor, and from about 0.06% to about 0.30% by weight of a compatibility improver of the class of diethylene glycol monoethyl ether, methoxy triglycol, and dimethoxy .tetraethylene glycol.3. A lubricating oil blend according to claim 2 wherein the compatibility improver is diethylene glycol monoethyl ether.4. A lubricating oil blend according to claim 2 wherein the compatibility improver is methoxy triglycol.5. A lubricating oil blend according to claim 2 wherein the compatibility improver is dimethoxy tetraethylene glycol.
