Abstract (en)
[origin: GB2359091A] This invention relates to a lubricating oil composition comprising a Group I basestock 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, wherein the basestock has a kinematic viscosity at 100{C (KV<SB>100</SB>) from about 2 cSt to 50 cSt (2 x 10<SP>-6</SP> to 50 x 10<SP>-6</SP> m<SP>2</SP>/sec), a saturates content of <90% w/w, an aromatics content of > 10% w/w and a sulphur content of > 0.03% w/w. The composition has an improved stability when compared with either a Group II, III or IV basestock containing the same antioxidant or a Group I basestock containing a dinuclear molybdenum dithiocarbamate.
