Lubricating oil compositions containing overbased calcium sulfonates and metal salts of alkyl catechol dithiophosphoric acid |
| abstract |
The anti-wear properties of lubricating oil compositions containing overbased calcium sulfonate are improved when a metal salt of an alkyl catechol ester of dithiophosphoric acid is added to the oil. Oil compositions containing this combination are useful as crankcase lubricants. |
