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 this product 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.
Arizona-based MD Helicopters, an aerospace company with products known for speed, strength and high performance, tested Mobil AGL extensively. The company started investigating lubrication improvements for its fleet’s transmissions when some operators experienced difficulty reaching a 3,000-hour main transmission overhaul period.
“Field evaluation tests on our single-engine product line allowed increasing the overhaul period of main rotor transmissions from 3,000 to 4,000 hours, if the transmission operated exclusively with Mobil AGL,” says MD Helicopters Engineer Scott Hendrickson. “The 33 percent increase in time between overhauls (TBO) provides operators with a corresponding decrease in operating costs.” MD Helicopters requires the use of Mobil AGL in all current production transmissions and recommends its use in older designs.
