摘要：

Mixtures of friction modifiers provide excellent friction performance to transmission fluids, where the friction modifiers include an N-substituted oxalic acid bisamide or amide-ester containing at least two hydrocarbyl groups of 12 to 22 carbon atoms; and an amide or thioamide represented by R1R2N—C(X)R3 where X is O or S, R1 and R2 are hydrocarbyl groups of at least 6 carbon atoms, and R3 is hydroxyalkyl group of 1 to 6 carbon atoms or a condensate thereof.
