In 2011, GM introduced its first-generation Dexos specification, Dexos1 Gen 2. This specification was designed to improve fuel economy, reduce emissions, and protect engines from wear. In 2021, GM introduced its second-generation Dexos specification, Dexos1 Gen 3. This specification builds on the performance of Gen 2 and includes additional features to improve engine performance and durability.
Table About Dexos Gen 2 and Gen 3
| Feature | Dexos1 Gen 2 | Dexos1 Gen 3 |
|---|---|---|
| Fuel economy | Improved | Improved even further |
| Emissions | Reduced | Reduced even further |
| Wear protection | Enhanced | Enhanced even further |
| Sludge Control | Improved | Improved even further |
Fuel Economy
Both Dexos1 Gen 2 and Gen 3 can help improve fuel economy. However, Gen 3 is designed to improve fuel economy even further. This is due to several factors, including improved oxidation stability and reduced friction.
Emissions
Both Dexos1 Gen 2 and Gen 3 can help reduce emissions. However, Gen 3 is designed to reduce emissions even further. This is due to several factors, including improved control of combustion byproducts.
Wear Protection
Both Dexos1 Gen 2 and Gen 3 can help protect engines from wear. However, Gen 3 is designed to provide even more excellent wear protection. This is due to several factors, including improved film strength and reduced friction.
Sludge Control
Both Dexos1 Gen 2 and Gen 3 can help control sludge formation. However, Gen 3 is designed to provide even better sludge control. This is due to several factors, including improved detergency and dispersancy.
List of Dexos Gen 2 vs. Gen 3
Here is a list of some of the critical differences between Dexos1 Gen 2 and Gen 3:
- Improved fuel economy
- Reduced emissions
- Enhanced wear protection
- Improved sludge control
- More stringent testing requirements
Conclusion About Dexos Gen 2 vs. Gen 3
Dexos1 Gen 3 is a significant improvement over Dexos1 Gen 2. It offers better fuel economy, reduced emissions, enhanced wear protection, and improved sludge control. If you are looking for the best possible engine protection, then Dexos1 Gen 3 is the right choice.
