Chevy Cruze engines typically use Dexos1 Gen 2 oil, commonly 0W-20 for gasoline engines; always verify the exact spec in your owner's manual.
Oil specifications by powertrain
To ensure you select the right oil, note the Cruze’s gasoline engines typically use Dexos1 Gen 2 oil with a lightweight viscosity, while diesel models in certain markets require Dexos2 oil. The following sections outline the common configurations.
Gasoline engines (most U.S./Canada Cruze models)
Most gasoline Cruze engines use Dexos1 Gen 2 oil. The most common viscosity for these engines is 0W-20, which supports fuel economy and cold-start performance. Some older model years or extreme climate conditions may call for 5W-30 Dexos1 Gen 2.
- Oil type: Dexos1 Gen 2 certified motor oil
- Viscosity: typically 0W-20; 5W-30 in certain climates or older engines
- Notes: Can be synthetic or synthetic blend; check the owner’s manual or the cap on the oil filler for Dexos labeling
Always confirm the exact grade with the manual, as a mis-match can affect warranty coverage and engine wear.
Diesel engines (European Cruze 2.0 CDTi)
In European markets, the Cruze diesel uses Dexos2-certified oil, usually in the 5W-30 or 5W-40 range, depending on year and climate. Check the owner's manual for the precise requirement for your vehicle.
- Oil type: Dexos2-certified motor oil
- Viscosity: commonly 5W-30 or 5W-40
Diesel engines require different specifications than gasoline engines, so do not use Dexos1 Gen 2 in these variants unless the manual states otherwise.
How to verify and maintain the right oil
If you're unsure, start with the owner's manual or the oil cap that often indicates the Dexos specification. For the Cruze, choosing a high-quality Dexos-certified oil and adhering to the recommended oil-change intervals is essential for engine health. GM often recommends change intervals aligned with the oil grade you use (synthetic often up to 7,500 miles; conventional oil 3,000–5,000 miles), but follow the manual.
Summary
In short: most Chevy Cruze models use Dexos1 Gen 2 oil, with 0W-20 being the common viscosity for gasoline engines. Diesel variants in Europe use Dexos2 oil (typically 5W-30 or 5W-40). Always verify the exact specification for your year and engine in the owner’s manual or at a Chevrolet dealer, and use a quality synthetic or synthetic-blend oil that meets the Dexos standard.
