AMSOIL Performance Test - AMSOIL Synthetic Gear Lube Outperforms Valvoline Gear Lube

"AMSOIL submitted its 75W-90 Synthetic Gear Lube (FGR) and Valvoline 75W-90 Gear Lube to an independent laboratory for quality comparison tests. The gear lubes were tested according to ASTM testing procedures in several critical performance areas, including oxidation resistance, viscosity retention and cold temperature fluidity. Oxidation resistance was measured using the L-60-1 Thermal Oxidation Stability Test, viscosity retention was measured using the KRL Shear Stability Test and cold temperature fluidity was measured using the Brookfield Viscosity Test. Additional load carrying, wear, extreme pressure and scoring protection tests were performed exclusively on AMSOIL 75W-90 Synthetic Gear Lube using the L-37 High Torque Axle Test and the L-42 High Speed Axle Test."
