Mobilube GX Series

Mobilube GX 80W-90, 140 are high performance, heavy duty gear lubricants formulated from high quality base oils and an advanced additive system.  These lubricants are engineered for automotive heavy-duty transmissions, axles, and final drives where protection against wear and scoring is required. They are recommended by ExxonMobil for use in applications  where API GL-4 service is required.

Today’s heavy equipment applications place higher performance demands on drivetrain lubricants.  Higher speeds, higher torque, and heavier loads require improved formulations to maximise equipment life and optimise operating costs.  Longer service intervals place additional demands on the gear lubricant requiring effective basestock and additive systems.  Mobilube GX 80W-90, 140 is engineered to meet these challenges.  The key benefits include:

Features	Advantages and Potential Benefits
Good thermal stability and resistance to high temperature oxidation	Extended gear and bearing life due to minimal deposits Longer seal life
Excellent rust and corrosion protection	Longer component life
Good low temperature lubrication	Reduced wear at start-up and ease of start-up
Compatible with typical seals and gaskets	Minimum leakage and reduced contamination

Recommended by ExxonMobil for use in:

•  Heavy duty manual transmissions, axles and final drives requiring API GL-4 level performance

•  Passenger cars, on highway light and heavy duty trucks, and commercial vehicles

•  Off highway industries including: construction, mining, quarrying, and agriculture

•  Other heavy duty industrial and automotive applications including hypoid gears operating under moderate to severe conditions
