Lubricant additive

A lubricant composition prepared by reacting sunflower oil with diethylenetriamine at a temperature in the range of 125.degree. to 175.degree. C. under an inert atmosphere employing a mole ratio of said sunflower oil to said diethylenetriamine of about 1:1 to produce a reaction product, reacting said reaction product with molybdenum trioxide at a temperature at a range of 125.degree. to 175.degree. C. under an inert atmosphere employing a mole ratio of said reaction product to said molybdenum trioxide of about 1:1 to produce a second reaction product, and reacting said second reaction product with sulfur at a temperature at a range of 125.degree. to 175.degree. C. under an inert atmosphere employing a mole ratio of said second reaction product to said sulfur ranging from about 1 to 2 respectively to produce said lubricant additive.

A lubricant additive prepared by reacting a triglyceride with a polyalkyene polyamine compound employing a mole ratio of triglyceride to polyalkylene polyamine in the range from about 2:1 to 1:3 respectively to produce a first reaction product, reacting said first reaction product with an acidic molybdenum compound employing a mole ratio of said first reaction product to said molybdenum compound in the range from about 2:1 to 1:3 respectively to produce a second reaction product, and reacting said second reaction product with a sulfur compound employing a mole ratio of said second reaction product based on molybdenum to said sulfur in the range from about 1:1 to 1:4 respectively to produce said lubricant additive, said polyalkylene polyamine compound being represented by the formula:

• ##STR4## in which R is hydrogen or a methyl radical and x has a value from 1 to 10.
