Marine Engine Lubrication |
| 摘要 |
Trunk piston marine engine crackcase lubrication is effected by a composition made by blending minor amounts of (A) a metal dithiophosphoric acid salt additive component comprising 50 mole % or more of a zinc di (C6 primary alkyl) dithiophosphate, and (B) an overbased metal detergent additive component, with (C) a major amount of an oil of lubricating viscosity. |

1. A trunk piston marine engine lubricating oil composition of TBN in the range of 20 to 60 mg KOH/g for a medium-speed compression-ignited marine engine which comprises or is made by blending
(A) an oil-soluble metal dithiophosphoric acid salt additive component, in a minor amount, which component comprises 50 mole % or more of a zinc dialkyl dithiophosphate where the alkyl group is a C6 primary alkyl group; and (B) an oil-soluble overbased metal detergent additive component, in a minor amount; with (C) an oil of lubricating viscosity in a major amount. |
