This invention provides an oil additive composition which may be used as an additive for both diesel engine lubricants and transmission lubricants. Additives useful in diesel engine lubricants often do not meet the requirements of specific transmission lubricant specifications. Surprisingly, the inventive composition, which comprises a combination of a neutral or basic alkali metal salt of a phenol sulfurized using elemental sulfur, a metal salt of a dithiophosphoric acid, an ashless dispersant, a calcium or magnesium sulfonate detergent, and a manganese carboxylate, may be used to create lubricants for both engine and transmission use.
