Extreme Pressure Gear Oil

Product Description

Mobilgear™ EP lubricants are a family of industrial extreme pressure gear lubricants formulated with high quality mineral oils, which help reduce sludge formation and increase oil service life.

 

Mobilgear EP oils contain an additive system that gives high load carrying ability, protection against wear and corrosion whilst ensuring good water handling properties.

 

Mobilgear EP oils are suitable for use wherever industrial gear oils are specified, in either splash or circulating systems, providing protection in applications with constant or shock loading.
