Abstract: A trunk piston marine engine lubricant comprises in respective minor amounts (A) an overbased metal hydrocarbyl-substituted hydroxybenzoate detergent system, and (B) a hydrocarbyl-substituted succinic acid anhydride, preferably made by halogen- or radical-assisted fractionalization processes, where the ratio of succinic anhydride to hydrocarbyl chains is in the range of 1.4 to 4. The lubricant, when used to lubricate such an engine fuelled by heavy fuel oil, exhibits improved control of asphaltene precipitation and deposition on engine surfaces.

Abstract: An oil composition comprises at least 50 percent by mass, based on the mass of the composition, of an oil and 0.01 to 25 percent by mass, based on the mass of the composition, of a polymer comprising at least one poly(lactone) segment. The at least one poly(lactone) segment is derived from a lactone substituted by one or two hydrocarbyl groups, or substituted hydrocarbyl groups, at least one such group having at least 4 carbon atoms. The oil compositions are suitable for use in the lubrication of the crankcase of internal combustion engines.
