- 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.
- GM Oxidation and Deposit (GMOD) Test consists of a 5.7L V8 engine running at 293ºF (100º hotter than normal) for 100 hours. Severe operating conditions test an oils ability to control viscosity increase, deposits and oil consumption.
64 percent more protection against oil breakdown than required by the GM dexos1® Gen 2 specification, ensuring protection in extreme temperatures.
