Gear Lubricant Testing

Evaluating the crucial properties of gear lubricants such as viscosity, shear stability, and wear performance testing is critical when assessing the performance of gear lubricants. This gear lubricant testing would include four-ball wear extreme pressure, pin and vee wear, foam testing, and more.  

Savant Labs offer most of the gear lubricant testing required under SAE J2360 specification for Automotive Gear Lubricants for Commercial and Military Use.
