  • 权利要求: 1. Use, in a lubricant composition comprising at least one base oil of 2 to 12 wt % by weight of the lubricant composition, of an ester having a viscosity at 100°C between 200 and 1,000 cSt, to improve the cleanliness of an engine, wherein the alcohol forming the esters is trimethylolpropane and the acid forming the esters is selected from the fatty acids comprising 6 to 24 carbon atoms.2. Use according to claim 1, wherein the viscosity of the ester at 100°C is between 200 and 900 cSt, preferably between 200 and 800, more preferably between 250 and 700 cSt.3. Use according to claim 1 or 2, wherein the ester is included in a proportion of 2 to 11%, preferably 3 to 11%, more preferably 3 to 10%, even more preferably 4 to 10% by weight in relation to the weight of the lubricant composition.4. Use according to any of claims 1 to 3, wherein the engine is a marine engine, preferably a 2-stroke marine engine.5. Method for improving the cleanliness of an engine, comprising the use in said engine of a lubricant composition comprising at least one base oil and 2 to 12% by weight of the lubricant composition of an ester having a viscosity at 100°C between 200 and 1,000 cSt, said ester being as defined in claim 1.
