The 2012 Chevrolet Cruze requires motor oil that meets GM’s Dexos1 Gen 1 specification, with the most common viscosity being 5W-30. Some climates or owner manuals may permit alternatives, but Dexos1 Gen 1 compatibility is the key requirement for this model year.
Oil specification and viscosity
To ensure proper protection and performance, use oil that is Dexos1 Gen 1 compliant. The typical viscosity for most 2012 Cruze engines is 5W-30, and you should verify the exact grade and any climate-specific allowances in your owner's manual.
Before listing the standard options, note that the Cruze’s two engines—1.8L and 1.4L turbo—share the Dexos1 Gen 1 requirement, so the oil should meet that specification regardless of engine variant.
The following options cover the common, Dexos1 Gen 1–approved choices used in many 2012 Cruzes:
- Dexos1 Gen 1 approved 5W-30 motor oil (synthetic blend or full synthetic).
Once you select an oil that meets Dexos1 Gen 1 and remains within the recommended viscosity, you can maintain regular oil-change intervals per the owner's manual or your vehicle’s maintenance schedule.
Engine-specific recommendations
1.8L engine (ECOTEC)
For the 1.8L ECOTEC engine, use Dexos1 Gen 1–compliant 5W-30 oil. A synthetic or synthetic-blend formulation is acceptable, and it should be chosen based on your climate, driving conditions, and dealership guidance. Avoid oils that do not meet Dexos1 Gen 1 specification.
1.4L turbo engine (LUV)
The 1.4L turbo also requires Dexos1 Gen 1–compliant oil, with 5W-30 being the typical recommendation. As with the 1.8L, you can choose a synthetic blend or full synthetic that meets the Dexos1 Gen 1 standard, and you should consult the owner's manual for any climate-specific notes.
Notes:
- Dexos1 Gen 1 isGM’s specification for these engines and is intended to ensure proper performance and protection.
- Some markets or maintenance plans may reference different Dexos generations or alternative grades; always confirm with your manual or a GM-certified technician.
Summary
In short, a 2012 Chevy Cruze should use Dexos1 Gen 1–compliant oil, with 5W-30 being the typical viscosity recommended for both the 1.8L and 1.4L turbo engines. Always verify the exact specification and grade in your owner's manual or with a GM dealer, and choose a synthetic blend or full synthetic that meets Dexos1 Gen 1 requirements.
