Abstract (en)

[origin: EP1918356A1] The present invention provides a lubricating oil composition which has excellent anti-wear properties for a metal pulley and a metal belt and initial anti-shudder properties and can retain the anti-shudder properties for a long period of time, suitable for use in a continuously variable transmission with a slip-controlled wet clutch and a metal belt. The lubricating oil composition comprises a lubricating base oil, (A) an alkylsalicylic acid metal salt and/or an (overbased) basic salt thereof, wherein the component ratio of the monoalkylsalicylic acid metal salt is from 85 to 100 percent by mole, the component ratio of the dialkylsalicylic acid metal salt is from 0 to 15 percent by mole and the component ratio of the 3-alkylsalicylic acid metal salt is from 40 to 100 percent by mole; (B) a specific nitrogen compound; and (C) a phosphorus-containing anti-wear agent.
