Abstract (en)
[origin: GB2359093A] A lubricating oil composition comprising a base stock and an antioxidant comprising an oil soluble trinuclear organomolybdenum compound of the generic formula: Mo<SB>3</SB>S<SB>x</SB>-(Q) (I) 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 (KV<SB>100</SB>) from about 2 cSt to 20 cSt (2 x 10<SP>-6</SP> to 20 x 10<SP>-6</SP> m<SP>2</SP>/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 good fuel economy improvement.
