Features

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.

Mobil AGL is formulated with synthesized hydrocarbon-based fluids. The combination of a naturally high viscosity index and a unique proprietary additive system helps enable Mobil AGL to provide outstanding performance in extreme service applications at high and low temperatures, well beyond the capabilities of mineral oils.

These scientifically engineered synthetic oils are specifically formulated to provide outstanding equipment protection, helping to extend oil life and enable problem-free operation. Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of Mobil AGL. Not least among the benefits, shown in work with OEMs, is the potential for significant reliability improvements in changing from mineral oil. These benefits are particularly evident in equipment which, by design, cannot avoid low overall efficiency, such as high ratio worm gears. Mobil AGL oils offer the following features and potential benefits:

Features Benefits
Superb high temperature thermal/oxidation resistance Helps extend equipment high temperature operating capability
Long oil life, helps reduce need and costs for oil change outs
Helps minimize sludge and deposits for trouble-free operation and long filter life
High Viscosity Index and absence of wax Maintains viscosity and film thickness at high temperatures
Exceptional low temperature performance, including start-up
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.
Helps minimize effects of micro slip in rolling contact bearings for longer rolling-element life potential
High load carrying capability Helps protect equipment and extend life; helps minimize unexpected downtime and extend service periods
Balanced additive combination Provides excellent performance in terms of rust and corrosion prevention, water separability, foam control, air release performance ensuring problem-free operation in a wide range of industrial applications and reduced operating costs

Applications

While Mobil AGL is compatible with mineral oil based products, admixture may detract from it's performance. Consequently it is recommended that before changing a system to Mobil AGL, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits. Mobil AGL is compatible with the following seal materials: fluorocarbon, polyacrylate, polyurethane ether, some silicone, ethylene/acrylic, chlorinated polyethylene, polysulfide, and some nitrile rubbers. There is the potential for substantial variations in the elastomers being used today. For best results, consult your equipment supplier, seal manufacturer, or your local ExxonMobil representative to verify compatibility. Mobil AGL is compatible with mineral oils but co-mingling with other types oils may lead to fluid incompatibility or detract from the total performance capability.

Specifications

Mobil AGL is recommended by many helicopter OEM's for use in transmissions. Please consult with your equipment OEM or your ExxonMobil representative to determine if Mobil AGL can be used in your application.
