Marine engine lubrication |
| abstract |
The trunk piston lubricating oil composition of TBN 20 to 60 comprises (A) a principal amount of a high saturated, low sulfur lubricating viscosity oil; (B) overbased metal hydroxybenzoate detergent additive; (C) polyisobutene succinic anhydride additive (1 to 7 mass%), and (D) meta linear pentadecyl phenol additive (0.1 to 10 mass%), wherein the weight ratio of (D) to (C) Is less than 1, and the combined throughput of (B), (C) and (D) is 5 to 30%. The composition is useful for improving the ability to disperse asphaltenes when lubricating medium speed compression-ignited marine engines in which heavy fuel oil is supplied as fuel. |
