| abstract |
A lubricating oil composition prepared by blending a lube base oil with (A) at least either molybdenum dithiocarbamate or molybdenum dithiophosphate and (B) an aromatic compound having at least one functional group selected from among hydroxyl, carboxyl, mercapto and thiocarboxyl groups on the aromatic ring. This composition enables the maintenance of low frictional characteristics and the continuation of fuel-cost saving performance over a long period, and can be reduced in the amount of an organomolybdenum compound to be added as a friction modifier. |
