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.
Features and Benefits
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.
