Extended Life Synthetic Motor Oil - Resists Oil Breakdown

GM Oxidation and Deposit (GMOD) Test Results — **GMOD engine test required for the GM dexos1**

XL Synthetic Motor Oil maintains its fluidity (viscosity) under the most extreme conditions. Some oils break down and significantly increase in viscosity after extended periods of high-temperature operation. These changes can cause excessive oil consumption, engine deposits, accelerated wear and difficult cold-starts. The GM Oxidation and Deposit (GMOD) Test consists of a 5.7L V8 engine running at 293°F (100° hotter than normal) for 100 hours. These severe operating conditions test an oils ability to control viscosity increase, deposits and oil consumption. The testing revealed that AMSOIL XL Synthetic Motor Oil provides 64 percent more protection against oil breakdown [1] than required by the GM dexos1® Gen 2 specification, ensuring protection in extreme temperature.
