Heavy Duty Automotive Gear Lubricants

Product Description

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


Features and Benefits

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 is engineered to meet these challenges.  The key benefits include:



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.
