Heavy Duty Automotive Gear Lubricants

Product Description

Mobilube GX 140 is high performance, heavy duty gear lubricant formulated from high quality base oil and an advanced additive system.  The 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 maximize equipment life and optimize operating costs.  Longer service intervals place additional demands on the gear lubricant requiring effective base stock and additive systems.  Mobilube GX 140 is engineered to meet these challenges.  The key benefits include:
