What kind of oil does a 2011 Chevy Colorado 3.7 take?
The 2011 Colorado with the 3.7-liter engine uses 5W-30 motor oil that meets Dexos1 specifications. You can use conventional, synthetic-blend, or full synthetic oil as long as it is Dexos1-rated.
Oil specification and viscosity
Knowing the right oil specification helps protect the engine and maintain warranty coverage. For this truck, the recommended viscosity is 5W-30, and the oil must be Dexos1-certified to meet GM’s standards.
- Dexos1-certified 5W-30 motor oil in any form: conventional, synthetic blend, or full synthetic.
- Do not use oils that lack Dexos1 certification or that specify a viscosity outside 5W-30 unless your manual explicitly allows a different option.
- Always verify the label and your owner’s manual; when in doubt, ask a dealer or trusted mechanic to confirm Dexos1 approval and the correct viscosity for your climate.
In practice, your choice among conventional, synthetic-blend, or full synthetic should hinge on cost, climate, and how you drive, as long as the oil remains Dexos1-certified and 5W-30.
