TowProof™ Gear Oil Technology

Keeping axles and their components cool improves fuel economy and extends fluid and component life, among other good things. That’s where Lubrizol's TowProof™ Gear Oil Technology comes in. Originally engineered for extreme heavy duty applications, TowProof has evolved into a 75W-90 formulation delivering unsurpassed performance for the passenger car and light duty market, including SUVs, pickups and Class 3 – Class 7 commercial vehicles. Here’s how:

A Comprehensive Package 

Utilizing a performance additive package in Group III and synthetic base stocks, TowProof makes formulating a SAE 75W-90 viscosity grade lubricant simple and cost effective. TowProof technology is flexible and gives oil marketers the ability to use existing blending capabilities, while also allowing formulators to use their existing base oil inventory and production capabilities. Formulating SAE 75W-90 viscosity grade lubricants can be difficult – TowProof makes it easy.

The Future is Now 

The multitude of gear lubricant formulations on today’s market use existing technology with finite performance levels. As a cutting-edge formulation, TowProof addresses the needs of the end user through a service-fill option dedicated for Class 3 to Class 7 vehicles. TowProof means:

Reduced operating temperatures

TowProof has been proven to reduce operating temperatures leading to improved axle efficiency, exceptional thermal stability, cleanliness, and seal compatibility.

Improved durability

TowProof has been rigorously tested and evaluated under the most severe conditions including extreme heat and extreme cold.

Improved axle efficiency

As fuel economy and power demands continue to increase, vehicles need a gear lubricant that can provide benefits like axle efficiency via reduced oxidation and improved viscosity.
