摘要： A clean performing gear oil for use in transmission oils and axle lubricants is provided. The gear oil having a Brookfield Viscosity at -12 DEG C ranging from about 1,000 to about 150,000 cP, comprises a base oil having a kinematic viscosity at 100 DEG C ranging from about 4.0 to about 41.0 cSt. Combined with the base oil is a mixture of a pour point depressant and a dispersant viscosity index improver. In addition, the gear oil includes a performance additive which imparts additional necessary properties for the overall performance of the gear oil in transmission and axle lubricants.
