Abstract: A lubricant composition for continuous variable transmissions which comprises a base oil and auxiliaries incorporated therein which are a sulfur-based extreme pressure additive (A), a phosphorus-based extreme pressure additive (B), and an alkaline earth metal-based detergent (C) It is superior in wear resistance and extreme pressure properties and keeps the coefficient of friction high for a long period of time, so that it is capable of transmitting a large capacity of torque when it is applied to an continuous variable transmission. It is particularly suitable for a transmission of metal belt type.
Abstract: Mist oil lubricants are disclosed based on polycarboxylic acid esters as the base oil which have added 1 to 5% of polyisobutylene Mn 400-2500 as stray mist suppressants.
