Title:

ENGINE OIL COMPOSITION

Document Type and Number:

WIPO Patent Application WO/1996/001302

Kind Code:

A1

Abstract:

An engine oil composition containing a specified molybdenum dithiocarbamate (MoDTC), a specified zinc dithiophosphate and a base oil as the essential ingredient, and further, if desirable, a specified half ester of polyglycerol. The composition serves to draw out the performance of MoDTC to the full so as to solve various problems related to friction, to suppress the deterioration of MoDTC itself, to keep such a high residual MoDTC content even after the deterioration of the oil that the effect of lowering friction and wear will last for long, and to contribute to fuel consumption improvement. Also the composition has a desirable coefficient of friction and good extreme-pressure performances even under both high extreme-pressure and hydrodynamic lubrication conditions.
