The 2014 Chevy Cruze uses Dexos-certified motor oil. Gasoline models (1.8L and 1.4L turbo) typically require Dexos1 Gen 2 oil, usually in 5W-30 viscosity, while the diesel Duramax-equipped version uses Dexos2 oil, commonly in 5W-40. Exact specifications can vary by market and engine, so consult the owner’s manual or a Chevrolet dealer if you’re unsure.
Engine-specific oil requirements
To answer definitively for each available powertrain, here are the typical oil standards you’ll see listed for the 2014 Cruze. Use the oil grade and Dexos specification that matches your engine to protect the engine and maintain warranty coverage.
Gasoline engines (1.8L and 1.4L Turbo)
Gasoline-powered Cruze models from 2014 generally require Dexos1 Gen 2-compliant motor oil in a 5W-30 viscosity. This specification is designed for GM gasoline engines to meet emissions and durability targets.
- Dexos1 Gen 2 certified engine oil, SAE 5W-30, synthetic or synthetic-blend (fully synthetic oil is commonly recommended).
In practice, using a Dexos1 Gen 2 5W-30 oil is the standard choice for these gasoline engines, ensuring proper lubrication across temperature ranges and compatibility with emissions systems. Always verify with the owner’s manual or dealer if you’re unsure about a non-standard viscosity.
Diesel engine (2.0L Duramax)
The diesel Cruze with the 2.0L Duramax engine uses Dexos2-certified oil. The typical recommendation is a 5W-40 synthetic oil, though Dexos2-certified 5W-30 can be acceptable in some markets if specified by GM for that model year and region.
- Dexos2 certified engine oil, SAE 5W-40, fully synthetic (API SN/older or newer specifications as approved by Dexos2).
Diesel engines with turbochargers and particulate filters rely on Dexos2 oil for better wear protection and exhaust aftertreatment compatibility. Always confirm the exact grade and specification for your market and vehicle with the owner's manual or a Chevy service advisor.
Additional notes
Oil grade and specification can vary by country, engine variant, and model year within the Cruze lineup. Always check your specific VIN-based manual or the label under the hood for the exact Dexos specification and viscosity recommended for your vehicle. Using oil that does not meet Dexos standards may affect warranty coverage and engine protection.
Summary
For gasoline-powered 2014 Cruzes (1.8L or 1.4L turbo), use Dexos1 Gen 2 oil in 5W-30. For the diesel 2.0L Duramax, use Dexos2 oil in 5W-40. Always verify the exact specification in the owner’s manual or with a Chevrolet dealer to ensure compatibility with your market and engine variant.
