Marine engine lubrication |
| abstract |
The invention relates to a marine engine lubricating oil. In particular to trunk piston lubricating oil compositions having TBN20-60 comprising (a) a major amount of a high saturates low sulfur oil of lubricating viscosity; (B) an overbased metal hydroxybenzoate detergent additive; (C) polyisobutylene succinic anhydride additive (1-7 mass%); and (D) a meta-linear pentadecylphenol additive (10.1-10 mass%), wherein the weight ratio of (D) to (C) is less than 1 and the combined treat rate of (B), (C) and (D) is 5-30%. The composition is useful for improving asphaltene dispersion when lubricating medium speed compression ignition marine engines fueled by heavy fuel oils. |
