Marine engine lubrication |
| abstract |
A trunk piston marine engine lubricating oil composition for a medium-speed compression-ignited marine engine comprises, in a major amount, an oil of lubricating viscosity containing 50 mass % or moreof a Group II basestock. and, in respective minor amounts, (A) an overbased metal hydrocarbyl-substituted hydroxybenzoate detergent having a basicity index of 4.5 or less, and (B) an overbased metalhydrocarbyl-substituted hydroxybenzoate detergent having a basicity index of greater than 4.5. The ratio of deterrent (A) to detergent (B), both expressed as mass of active ingredient, is in the rangefrom 0.5 to 15. The trunk piston marine engine lubricating oil composition has a TBN (using ASTM D2896) of 20 to 60. |
