The subsequent dexos2 revision, introduced later, focused on improving fuel economy and meeting the demands of turbocharged engines. While both standards cover gasoline engines, dexos2 places stricter requirements on oil longevity and thermal stability.
Dexos Maintenance Best Practices for Engine Health and Longevity
The viscosity grade must match the recommendations in your owner’s manual, but the certification logo is the definitive proof that the formulation meets GM standards. Monitoring oil levels between services, using high-quality filters, and avoiding severe driving conditions without adjustments all contribute to engine health.
When you see the dexos1 or dexos2 certification mark on a container, it confirms that the oil has passed a series of rigorous laboratory tests designed by GM. Using a non-certified oil risks inadequate protection, which can lead to increased engine wear or reduced efficiency over time.
