Lubricant additive formulation

An engine treatment oil additive used in combination with a conventional crankcase lubricant at about a 20 to about a 25 volume/percent comprising a synergistic combination of chemical constituents, said concentrate consisting essentially of:

• from 0.05 weight percent to 5.0 weight percent of an oil soluble molybdenum additive;
• from 10.0 volume percent to 95 volume percent of a synthetic base stock;
• from 0.5 volume percent to 35.0 volume percent of a dispersant inhibitor;
• from 5.0 volume percent to 95.0 volume percent of a mineral oil base stock;
• from 0.5 weight percent to 25.0 weight percent of a viscosity index improver;
• and
• from 0.01 volume percent to 0.10 volume percent of a boron agent.

A process of manufacturing an improved lubricating composition additive consisting essentially of the steps of mixing together at about 0-100.degree. C.:

• a. about 0.35-15 wt. % of oil soluble molybdenum additive;
• b. about 0.25-25 wt. % conventional and/or synthetic motor oil or grease;
• c. about 0-90 vol. wt. % of synthetic base stock comprising diesters and/or polyolefins;
• d. about 0-15 wt. % of viscosity index improver;
• and
• e. from 0.01 volume percent to 0.10 volume percent of a boron agent;
• said concentrate, when diluted with about 0.5-15 parts of said motor oil in a crankcase of an internal combustion engine, providing that engine with improved wear reduction, fuel economy and viscosity stability.
