Chevrolet does not endorse a single oil brand; it requires engine oil that meets the dexos1 specification (Gen 1 or Gen 2) and the correct viscosity for your model and climate. In practice, many reputable brands offer dexos-certified oils, so you can choose a trusted brand as long as the product carries the dexos label and matches the recommended viscosity.
The guidance from Chevrolet centers on the specification and viscosity, not a specific brand. This article explains how to interpret the dexos1 standard, what to look for on the bottle, and how to choose the right oil for your Chevy.
Dexos1 specification and brand options
Chevrolet’s requirement focuses on the oil meeting the dexos1 standard rather than endorsing one particular brand. The exact generation (Gen 1 vs Gen 2) depends on your engine and model year.
- Dexos1 Gen 2 compatibility for most 2016+ Chevrolet models; older engines may use Dexos1 Gen 1. Look for "dexos1 Gen 2" or "dexos1 Gen 1" on the bottle label.
- Viscosity guidance varies by model and climate; common recommendations include 0W-20 for many modern engines and 5W-30 for others. Always verify in the owner's manual or on the oil cap.
- Brand options: Many reputable brands offer dexos-certified oils, including Mobil 1, Castrol, Pennzoil, Valvoline, and Shell, among others. Availability depends on region.
- Certifications and warranty: Choose an oil that is labeled dexos-certified and API-rated (as applicable). Using non-dexos oil may affect warranty coverage in some cases, per GM guidelines.
In short, the critical factor is dexos certification and the correct viscosity for your Chevy. If you’re unsure, consult the owner’s manual or contact a Chevrolet dealership for confirmation.
How to verify the right oil for your Chevrolet model
Next steps include checking the owner’s manual, the oil filler cap, or GM’s service documentation for the precise viscosity and dexos Gen requirement for your engine. For most newer vehicles, dexos1 Gen 2 is standard; older models may specify Dexos1 Gen 1.
What to look for on the bottle
On the oil bottle, confirm the presence of dexos1 Gen 2 (or Dexos1 Gen 1) and the viscosity grade (such as 0W-20 or 5W-30). The API rating (e.g., API SN, SP) is also a helpful confirmation of performance standards.
Tips from service professionals
When in doubt, ask a Chevy service adviser or reference the VIN-specific service bulletin, which can indicate the exact oil specification for your engine family.
Summary
Chevrolet’s oil guidance emphasizes meeting the dexos1 specification rather than endorsing a single brand. For most modern Chevys, dexos1 Gen 2 is the standard; older engines may use Dexos1 Gen 1. Always choose a dexos-certified oil in the correct viscosity for your model and climate, and verify label details before purchasing. If you need precise confirmation, consult your owner’s manual or a Chevrolet dealer/service professional.

What brand of oil do Chevy dealerships use?
Selecting your oil
From conventional to full synthetic, your Chevrolet Certified Service experts offer a range of oil types, including ACDelco Conventional Oil, ACDelco dexos1TM Full Synthetic, and Mobil 1TM Full Synthetic.
What happens if I don't use Dexos oil?
Using oil that doesn't meet Dexos standards in an engine that requires it could void your warranty. Dexos is highly regarded, and many automakers now use oils that meet or exceed these standards. One major benefit of using Dexos-approved oil is the peace of mind it offers.
