Abstract:
A low S marine fuel trunk piston diesel engine lubricant includes an overbased metal detergent; a zinc dihydrocarbyl dithiophosphate; optionally an aminic antioxidant; and a borated ashless dispersant. The lubricant exhibits improved thermal and oxidative stability and improved high temperature detergency.

Claim (Index 1):
A low sulfur marine fuel trunk piston diesel engine lubricating oil composition comprising or made of admixing\n (A) an oil of lubricating viscosity in a major amount; and, in respective minor amounts (B) an overbased metal detergent comprising a metal salt of a surfactant selected from a hydrocarbyl-substituted phenol, a hydrocarbyl-substituted sulfonic acid, and a hydrocarbyl-substituted hydroxybenzoic acid; (C) a zinc dihydrocarbyldithiophosphate in an amount of 50 to 1000 ppm by weight in terms of P atoms; (D) optionally, an aminic anti-oxidant in an amount of up to 400 ppm by weight in terms of N atoms; and (E) a borated ashless dispersant in an amount of 10 to 500 ppm by weight in terms of B atoms; the composition having a TBN of 5 to less than 20 mg KOH/g.
