This gear composition has remarkably excellent oxidation stability and abrasion resistance at elevated temperatures and a good flowability at low temperatures.

Differentials use similar gear oil, but likely different additives for limited-slip clutches and the like.

Standard (“manual”) transmissions use gear oil (like heavy, strong-smelling motor oil; see “Gear Oil” below) or the manufacturer’s proprietary manual transmission fluid.

Multi-viscosity/Multi Grade Oil - Engine or gear oil that meets the requirements of more than one SAE viscosity grade classification, and that can be used over a wider temperature range than a single grade oil.

Engine or gear oil that meets the requirements of more than one SAE viscosity grade classification, and that can be used over a wider temperature range than a single grade oil.

For example, gear oil must be heated to + 10 C before starting gear equipment.

The invention relates to industrial gear oil compositions that have been specially designed to be vibration resistant.

The composition comprises a major amount of base oil comprising a mixture of a mineral base oil and polybutene; and 0.1 to 0.5 wt % of carbon black, based on the total weight of the gear oil composition.

Manual transmission fluid may vary, however, using either plain motor oil, a transmission oil called heavyweight hypoid gear oil, or automatic transmission fluid.
