What oil does Chevy Cruze use?
The Chevy Cruze generally uses engine oils that meet GM’s Dexos specifications: Dexos1 Gen 2 for gasoline engines (typically 0W-20 or 5W-30, depending on climate and model year) and Dexos2 for diesel variants (often around 5W-40). Always confirm the exact requirement for your specific model year and market by checking the owner’s manual or asking a Chevrolet dealer.
Oil specification and compatibility
Gasoline engines (1.8L and 1.4L turbo)
Most Cruze gasoline engines require Dexos1 Gen 2 certified oils. The recommended viscosity options are commonly 0W-20 or 5W-30, depending on climate and engine variant. Use a quality oil that explicitly carries the Dexos1 Gen 2 certification.
- Dexos1 Gen 2 certification is required for gasoline Cruze engines in most markets.
- Common viscosities offered for these engines are 0W-20 and 5W-30; the exact grade depends on engine year and climate.
- Prefer full-synthetic or synthetic-blend oils that meet Dexos1 Gen 2 specifications.
Conclusion: For gasoline Cruze models, look for Dexos1 Gen 2 oils in 0W-20 or 5W-30, with the precise viscosity guided by your manual and climate.
Diesel engines (where available)
Diesel Cruze variants generally require Dexos2-certified oils. The common viscosity in many markets is 5W-40, but the exact grade can vary by country and model year; always verify with the manual or dealer.
- Dexos2 certification is typically required for diesel Cruze engines.
- Common viscosity used is around 5W-40 in many markets.
- Choose a high-quality, synthetic or synthetic-blend oil that meets Dexos2 specifications.
Conclusion: If you own a Cruze with a diesel engine, use a Dexos2-certified oil of the grade specified for your market and year, commonly 5W-40.
Recommended oil viscosities by climate and engine type
To help navigate practice-level choices, here are general guidance points you’ll often see in manuals and service notes. Always follow the exact specification printed in your owner’s manual for your engine and region.
- Cold or mixed climates: 0W-20 Dexos1 Gen 2 is frequently recommended for gasoline Cruze engines.
- Moderate to warm climates: 5W-30 Dexos1 Gen 2 is commonly used for gasoline engines, depending on the model year.
- Diesel engines in hot climates or high-load conditions: 5W-40 Dexos2 is commonly used, though check local guidance.
Conclusion: Start with the Dexos specification (Dexos1 Gen 2 for gasoline, Dexos2 for diesel) and select 0W-20, 5W-30, or 5W-40 based on your climate and engine, as specified by GM for your vehicle.
How to verify the right oil for your Cruze
- Check the owner's manual for the exact Dexos specification and viscosity recommended for your year and market.
- Inspect the oil cap or oil fill label in the engine bay, which sometimes indicates the required viscosity or Dexos standard.
- Look for Dexos labeling on oil containers at the parts store or service shop; differentiate between Dexos1 Gen 2 (gasoline) and Dexos2 (diesel).
- Consult a Chevrolet dealer or qualified technician if you’re unsure about your model year or engine variant.
Conclusion: Verifying the Dexos specification and the correct viscosity with your manual or a dealer ensures you use the right oil and protects your engine warranty.
Summary
In short, the Chevy Cruze commonly uses Dexos1 Gen 2 oils for gasoline engines (usually 0W-20 or 5W-30) and Dexos2 oils for diesel variants (often 5W-40), with exact grades determined by model year, engine, and climate. Always confirm the specification in your owner’s manual or by consulting a Chevrolet dealer to ensure compatibility and optimal engine health.
