| 主权项 | 1. A lubricant composition for 4-stroke or 2-stroke marine engine, comprising: a) at least one lubricating base oil, b) from 0.2 to 2% by weight of at least one olefin copolymer, wherein the olefin copolymer is a straight-chain copolymer of ethylene and propylene, c) from 0.3 to 5% by weight of at least one copolymer of styrene and hydrogenated isoprene, d) from 0.5 to 1.5% by weight of at least one glycerol ester, wherein the glycerol ester is a mixed ester of glycerol with at least one fatty acid having 8 to 24 carbon atoms and at least one carboxylic acid also comprising a hydroxyphenyl function, and e) from 5 to 10% by weight of at least one detergent, based on the total weight of the lubricant composition. | ||
