Infilrex 33

Limited Slip Gear Lubricant

Product Description

Infilrex 33 is a high performance automotive gear lubricant formulated from select base oils and an advanced additive system especially for limited-slip differentials. According to ExxonMobil, this lubricant is of Quality Level API GL-4 performance in both heavy duty and passenger car differentials, axles and final drives.

Features and Benefits

Today's truck and automotive equipment applications place higher performance demands on drive train lubricant. Higher speeds, higher torque, heavier loads and limited-slip capability require improved formulations to maximise differential life and optimise performance. Longer service intervals place additional demands on the gear lubricant. Infilrex 33 is engineered to help meet these challenges.

The key benefits include:

Features	Potential Benefits
Excellent frictional properties	Effective limited slip performance
Good thermal stability and resistance to high temperature oxidation	Extended gear and bearing life due to minimal deposits and longer seal life
Help protects against low speed/high torque wear and against high speed scoring	Increased load carrying capability reducing operating costs
Very good rust, staining and corrosion protection	Reduce wear and maintenance costs
Effective low temperature lubrication	Reduced wear and ease of start up
Good resistance to foaming	Maintains film strength for reliable lubrication

Applications

Limited slip differentials, axles and final drives requiring API GL-4 level performance
Passenger cars, on highway light and heavy duty trucks
Off highway industries including: railway, construction, mining, quarrying, and agriculture
Other heavy duty industrial gear drives including hypoid and other gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque conditions prevail
Not intended transmissions or transaxles for which engine oil or automatic transmission fluids are recommended.
