The answer depends on which engine your Colorado has: most gasoline engines require Dexos1 Gen 2 oil with a viscosity of 5W-30, while the 2.8L Duramax diesel uses Dexos2 oil with a viscosity of 5W-40. Always confirm with the owner's manual or GM's official service information for your exact configuration.
The 2022 Chevrolet Colorado is offered with multiple powertrains, and oil specifications are engine-specific. Using the wrong oil can affect performance, emissions, and warranty coverage, so it’s important to match the oil to the correct Dexos specification and viscosity for your engine.
