ANTIOXIDANT ADDITIVE COMPOSITION FOR LUBRICATING OILS |
摘要 |
This invention relates to a lubricating oil composition comprising a base stock and an antioxidant comprising an oil soluble trinuclear organomolybden um compound of the generic formula (I): Mo3Sx-(Q) wherein x is from 4 to 10 and Q is a core group, which may be a ligand, and at least one other compound selected from a phenolic and an aminic compound wherein the basestock has a kinematic viscosity at 100 ~C (KV100) from about 2 cSt to 20 eSt (2 x 10-6 t o 20 x 10-6 m2/sec) and a saturates content of at least 85 %. The composition has a high oxidation stability, reduced deposit formation and is capable of giving rise to a good fuel economy improvement.
