What brand of oil do Chevrolet dealers use?
Chevrolet dealers typically use Dexos1 Gen 2 certified motor oil, with ACDelco Dexos1 Gen 2 as the GM-branded option, though other brands that meet the Dexos1 Gen 2 specification may be used depending on the dealer and region.
Understanding Dexos1 Gen 2 and GM’s oil policy
Dexos1 Gen 2 is GM’s current specification for gasoline engines. Oils that meet this standard pass specific tests for wear protection, deposits, and compatibility with GM engines, and are required for many new Chevrolet models to maintain warranty and performance. While ACDelco Dexos1 Gen 2 is GM’s own brand of Dexos-certified oil, the network also uses other manufacturers’ Dexos1 Gen 2 oils, depending on supply and regional contracts.
What qualifies as a Dexos1 Gen 2 oil?
Any motor oil that carries the Dexos1 Gen 2 certification and is the correct viscosity for your engine (most commonly 0W-20 or 5W-30 in modern Chevrolets) is acceptable for GM service centers. The company label on the bottle will indicate Dexos1 Gen 2 compliance.
Before listing brands commonly used by Chevrolet dealers, note that availability varies by market and contract.
- ACDelco Dexos1 Gen 2
- Mobil 1 Dexos1 Gen 2 certified oils
- Pennzoil Dexos1 Gen 2 certified oils
- Valvoline Dexos1 Gen 2 certified oils
- Castrol Dexos1 Gen 2 certified oils
Concluding paragraph: The exact brand used at a given dealership depends on supply contracts and regional practice, but it must be Dexos1 Gen 2 certified and match the vehicle’s recommended viscosity.
Practical implications for Chevy owners
When you bring your vehicle in for an oil change, you can ask the service advisor which Dexos1 Gen 2 oil brand will be used and confirm the viscosity (0W-20 is common for many newer Chevrolet engines). If you have a brand preference, you can request it as long as it is certified Dexos1 Gen 2.
Summary
Chevrolet dealers generally use Dexos1 Gen 2 certified motor oil. The GM-branded option is ACDelco Dexos1 Gen 2, but other Dexos1 Gen 2 oils from major brands are commonly used as well. The key requirement is Dexos1 Gen 2 certification and the appropriate viscosity for your vehicle, with actual brand choice determined by dealer contracts and regional supply.
