A process for reducing liner lacquering in a marine diesel is described, which process comprises adding to the fuel a liner lacquering reducing amount of a fuel-soluble composition comprising (A) at least one diesel detergent, and (B) at least one combustion improver. The detergent is preferably an imide or amide formed by the reaction of a polyalkene substituted succinic acylating agent and an amine, particularly a succinimide, and the combustion improver is preferably a cerium oxidic compound. |
