ABSTRACT:
Lubricating oils having improved antioxidant and anti-wear properties are obtained by adding a minor amount of a reaction product made by reacting at least one aliphatic olefinically unsaturated hydrocarbon containing from about 8 to 36 carbon atoms (preferably an .alpha.-olefin) concurrently with sulfur and at least one fatty acid ester (preferably an oil such as cottonseed oil) to obtain a reaction intermediate and reacting this intermediate with additional sulfur and a dimer of cyclopentadiene or lower C.sub.1-4 alkyl substituted cyclopentadiene dimers, such as methylcyclopentadiene dimer.
