- 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.
