Mobil Synthetic Gear Oil 75W-90

Mobil Synthetic Gear Oil 75W-90 is a fully synthetic gear lubricant formulated from synthetic base oils and an advanced additive system.  It is designed for use in many railway gearboxes and provides excellent load-carrying capability where extreme pressures and shock loading are expected.  This gear oil  provides excellent thermal and oxidation stability, high Viscosity Index (VI), extremely low pour point, and low-temperature fluidity.  Mobil Synthetic Gear Oil 75W-90  meets the API GL-5 performance level.

Railway gearbox designs have changed and increased the requirements of fluids to deliver higher performance including potentially increased productivity and reduced operating costs.   Mobil Synthetic Gear Oil 75W-90  is engineered to deliver exceptional performance and contribute to lower  total lubrication-related operating costs. The key potential benefits include:

Features	Advantages and Potential Benefits
Exceptional thermal stability and resistance to high temperature oxidation	Extended gear and bearing life due to minimal deposits Longer seal life
Outstanding protection against low speed/high torque wear and high speed scoring	Increased load-carrying capability. Contribution to reduced maintenance costs and longer equipment life
Enhanced frictional properties	Helps to reduce operating costs
Outstanding low temperature fluidity versus mineral oils	Contribution to reduced wear and ease of start up
Good resistance to foaming	Maintains film strength for reliable lubrication

Recommended by ExxonMobil for use in

•  Gearboxes requiring API GL-5 performance

•  Not recommended for applications requiring API GL-4 Level performance

•  Not intended for automatic, manual, or semiautomatic transmissions for which engine oil or automatic transmission fluids are recommended.

Please verify OEM requirements and oil selection criteria for your specific railway gearbox and application.
