Lubricating oils having improved antioxidant and antiwear properties are obtained by adding a minor amount of a reaction product made by reacting an olefinic hydrocarbon containing about 6-18 carbon atoms and about 1-3 olefinic double bonds concurrently with sulfur and hydrogen sulfide to obtain a reaction intermediate and reacting this intermediate with additional olefin hydrocarbon which may be the same or different. Preferred olefinic hydrocarbons are dicyclopentadiene and alloocimene. |
