About Mobil AGL - Synthetic Aviation Gear Lubricant

Mobil AGL is a supreme performance gear and bearing oil designed to provide outstanding service in terms of equipment protection, oil life and problem-free operation helping to enable increased customer productivity in civilian and military helicopter transmissions. This scientifically engineered oil is formulated from base fluids with an inherently high viscosity index and a unique proprietary, additive system which enables it to provide outstanding performance in extreme service applications at high and low temperatures, well beyond the capabilities of mineral oils. This product is resistant to mechanical shear, even in heavily loaded gear and high shear bearing applications.

Mobil AGL has a low traction coefficient, which derives from the molecular structure of the base stock used. This results in low fluid friction in the load zone of non-conforming surfaces such as gears and rolling contact bearings. Low fluid friction produces lower operating temperatures and improved gear efficiency, which translates into reduced power and allows for more economical equipment design.

Advantages and Potential Benefits:

Superb high temperature thermal/oxidation resistance helps extend equipment high temperature operating capability, leading to long oil life, helps reduce need and costs for oil change outs

1. High Viscosity Index and absence of wax maintains viscosity and film thickness at high temperatures also giving exceptional low temperature performance, including start-up
2. Low traction coefficient reduces overall friction and can increase efficiency in sliding mechanisms such as gearing, with potential for reduced power consumption and lower steady-state operating temperatures.
3. High load carrying capability helps protect equipment and extend life; helps minimize unexpected downtime and extend service periods

Applications:

1. Mobil AGL offers measurably better performance in lubrication of a helicopter transmission than Type I (MIL-L-7808) and Type II (MIL-L-23699) turbine oils at high and low temperatures as well as wear resistance that is especially beneficial to military and other helicopters operating under unusual stresses.
