The short answer is that it depends on the model and engine. Most 2017 Chevrolets use Dexos1 Gen 2 approved oil, with 0W-20 being common for many four‑cylinder gasoline engines and 5W‑30 used for larger V6/V8 engines or in colder climates. Always verify with the owner's manual or the oil cap.
The question spans a wide range of vehicles Chevrolet sold in 2017—from compact cars to full‑size pickups and SUVs—each with its own engine family and lubrication needs. The following explainer lays out the general rules GM uses for 2017 models and how to confirm the exact specification for your specific vehicle.
Dexos1 Gen 2 and the Chevrolet oil standard
Since 2014, General Motors has required Dexos oil for most of its gasoline engines. Dexos1 Gen 2 is the modern specification you’ll typically see on 2017 Chevrolets. Oil labeled Dexos1 Gen 2 is designed for better fuel economy, oxidation resistance, and engine protection in direct‑injected engines. Your 2017 Chevy will almost always require Dexos1 Gen 2 or an equivalent Dexos‑certified product.
Typical viscosity ranges you’ll encounter
Oil viscosity describes how thick the oil is at different temperatures. For 2017 Chevys, the recommended viscosities vary by engine type and climate, but two broad patterns recur across many models.
Four‑cylinder and smaller engines
Many 2017 Chevrolet four‑cylinder gasoline engines call for 0W‑20 synthetic or synthetic‑blend Dexos1 Gen 2 oil. This lightweight oil helps with cold starts and fuel efficiency, and it’s compatible with turbocharged and naturally aspirated four‑cylinder engines in models like the Cruze, Malibu, and Equinox. Always confirm for your specific engine though, as some variants may use a slightly different specification.
V6 and V8 engines
For larger gasoline engines such as several V6 and V8 options in trucks and SUVs, 5W‑30 Dexos1 Gen 2 is a common specification. This viscosity provides adequate protection for higher load and heat scenarios often found in trucks, SUVs, and performance variants. Again, check your manual for the exact requirement, as some engines or climates might allow or require a different viscosity.
Diesel Duramax engines (if applicable)
Some 2017 Chevrolet pickups use a Duramax diesel engine and require Dexos2‑certified oil. If your vehicle has a Duramax diesel, follow Dexos2 requirements and refer to the owner’s manual for the exact viscosity and grade.
How to confirm the exact oil for your 2017 Chevy
Because Chevrolet offered many models in 2017, the most reliable source is your vehicle’s documentation and labeling. Start with these checks:
- The owner’s manual page that lists oil specification and viscosity.
- The oil filler cap, which often states the required viscosity and sometimes the Dexos certification.
- The stamped oil specification on the dipstick or in the service schedule.
- GM’s official service site or your local dealer, which can provide model- and VIN-specific guidance.
What to do if you’re not sure
If you’re unsure about your exact 2017 Chevy, a quick call or visit to a Chevrolet dealer or trusted mechanic will get you the precise Dexos1 Gen 2 oil (or Dexos2 for diesels) and viscosity for your engine. Using the wrong oil can affect lubrication, engine efficiency, and warranties, so it’s worth confirming.
Summary
In 2017, Chevrolet largely used Dexos1 Gen 2‑certified oils across its gasoline engines. The typical viscosities were 0W‑20 for many four‑cylinder units and 5W‑30 for larger V6/V8 powertrains or in colder climates. Diesel Duramax engines, when present, require Dexos2 oil. The exact specification depends on the model and engine, so always verify with the owner’s manual, the oil cap, or a Chevrolet dealer. When in doubt, start with a Dexos1 Gen 2 oil in 0W‑20 for most modern GM engines and adjust to 5W‑30 or Dexos2 as required by your engine.
