ABSTRACT:
An oil composition for continuously variable transmissions (CVT) comprising a base oil, (A) a sulfonate, (B) an ashless dispersant, (C) an acid amide, (D) an organomolybdenum compound, and (E) an amine antioxidant.
The oil composition for CVT prevents the scratching phenomenon while the transmitted power is kept large in CVT of a belt type used for automatic transmissions of automobiles. The gradient in the .mu.-V characteristic can be kept positive for a long time.
