The present invention provides for an improved lubricating oil composition for automatic transmissions and internal combustion engines, as well as novel oil soluble or oil dispersible compounds which are useful as antiwear/antioxidant additives when incorporated in such oils. The additives of this invention comprise substituted quinones which are the reaction product of a benzoquinone and a thio compound having the formula RSH or (R?1-0) (R2¿-0) PSSH wherein R, R?1 and R2¿ are hydrocarbyl radicals. These additives have been found to impart good antiwear and antioxidant properties to such oils and fluids, particularly when used in combination with other conventional oil additive components. |
