Lubricating composition comprising molybdenum compound and viscosity index improver

摘要

The present invention provides a lubricating composition comprising:
- a base oil;
- one or more organomolybdenum compounds; and
- one or more dispersant-viscosity index improver compounds. Preferably, the one or more dispersant-viscosity index improver compounds are selected from compounds according to formula (I),
wherein n is an integer in the range of from 1 to 20, preferably 10 to 20, m is an integer in the range of from 75 to 200, y is an integer in the range of from 2 to 6 and x is an integer in the range of from 200 to 600.
