Polyisobutylene of 400 - 8,000 molecular weight and 50 - 50,000 mm 2 /sec kinematic viscosity at 100°C, when used as an additive at 1 - 25 mass % in a trunk piston diesel engine lubricant composition, reduces deposit formation in a centrifuge of a trunk piston diesel engine when the composition lubricates the engine during operation.
