In short: use Dexos1 Gen 2 motor oil, typically 5W-30 synthetic, for a 2013 Cruze. The exact viscosity and fill capacity depend on the engine variant (1.8L or 1.4L turbo) and your climate, so always verify in the owner's manual.
Engine variants and oil specs
The 2013 Chevy Cruze offered two gasoline engines, and both require motor oil that meets GM’s Dexos1 Gen 2 specification. The guidance below reflects common practice, but the official manual should be your primary reference.
- 1.8L I4 engine: Dexos1 Gen 2 approved oil, typically 5W-30 synthetic or synthetic blend. Use the viscosity recommended in the owner’s manual for your climate.
- 1.4L turbo engine: Dexos1 Gen 2 approved oil, usually 5W-30 synthetic. As with the 1.8L, follow the manual’s climate-based viscosity guidance.
In practice, both engines rely on Dexos1 Gen 2 compliance as the key requirement, with 5W-30 synthetic being the most common recommendation across many markets. Always confirm the exact grade and capacity for your specific build and location.
How to confirm the exact specification
Because oil viscosity and capacity can vary by engine and climate, verify using these sources and checks before your next oil change.
- Consult the owner's manual or the GM maintenance schedule for the Dexos1 Gen 2 specification and the recommended viscosity for your engine and region.
- Inspect the under-hood oil fill cap and the oil change sticker (often found on the driver's door jamb) for the recommended grade and Dexos qualification.
- Choose a reputable oil brand that clearly states Dexos1 Gen 2 certification on the bottle, and ensure it is the correct viscosity for your climate.
- Keep receipts or notes from each oil change to verify the oil grade used and to track maintenance intervals.
If you’re unsure after checking these sources, ask a Chevrolet dealer or a trusted mechanic to confirm the exact Dexos1 Gen 2 grade and viscosity for your vehicle’s engine and local conditions. Using the wrong oil can affect performance and may impact warranties.
Maintenance notes and tips
Beyond selecting the right Dexos1 Gen 2 oil, observe GM’s recommended service intervals and use a quality oil filter. Synthetic oils generally offer longer change intervals, but follow the oil life monitoring system or manual guidance if your driving is severe or frequent short trips. Don’t mix oil brands or specifications unless the manual explicitly allows it, and always replace the filter at each oil change.
Why Dexos1 Gen 2 matters
Dexos1 Gen 2 is GM’s official oil specification designed to meet the engine’s tolerances, protection, and performance requirements across a wide range of temperatures and driving conditions. Using oil that meets Dexos1 Gen 2 helps protect the engine, maintain performance, and preserve warranty coverage where applicable.
Summary
The 2013 Chevy Cruze requires motor oil that meets Dexos1 Gen 2, with 5W-30 synthetic being the most commonly recommended viscosity. Engine variant (1.8L or 1.4L turbo) and climate determine the exact grade and fill capacity, so consult the owner's manual and the vehicle’s specification labels to confirm. Use a Dexos1 Gen 2-certified oil from a reputable brand, change the oil and filter at the recommended intervals, and monitor oil life to keep the Cruze running smoothly.
