Using substandard oil can affect engine performance and, in the worst-case-scenario, may damage or harm the engine. GM wants to make sure that every car, anywhere in the world, regardless of manufacturer, has access to the highest quality oil. The dexos^® engine oil specification represents a high quality, robust oil formulated to some of the most rigorous specifications in the industry. Only licensed dexos^® products have been certified by GM to meet the dexos^® specification.

Dexos^® 1 Gen 3 is being used by GM to meet their newest hardware performance needs. GM has, once again, improved performance with dexos^® 1 Gen 3 in almost all areas, adding increased performance limits for the existing tests and replaced the legacy GMVFE fuel economy and GMSPI low-speed preignition tests with more demanding versions. Areas where Gen 3 outperforms Gen 2 are:

• Fuel Economy and Fuel Economy Retention
• Sludge Control
• Viscosity Increase Resistance
• High Temperature Deposit Control
• Volatility
• Chain Wear Resistance
• LSPI Prevention
• Turbo Protection

Yes, dexos^® 1 Gen 3 is backward compatible with previous generation dexos^® 1.

SUPREME Synthetic 0W-20, 5W-30 and 5W-20 and SUPREME Synthetic Hybrid 0W-20 are licensed by GM and were designed to exceed the GM dexos^® 1 Gen 3 global gasoline engine oil specification. These oils have gone through rigorous testing requirements and help protect gasoline direct injected and turbocharged direct injected engines from accelerated timing-chain wear and harmful damage caused by abnormal combustion events.

GM dexos^® 1 Gen 2 products were still available when Gen 3 products hit the shelves due to inventories transitioning. All Gen 2 products are now obsolete and all suppliers and customers should be using GM dexos^® 1 Gen 3 licensed products.
