The 2018 Chevy Cruze does not have a single universal oil capacity. In U.S. models, the engine choice determines the amount: the 1.4-liter turbo gasoline engine typically requires about 4.2 quarts of oil with the filter, while the 1.6-liter diesel uses around 5.0 quarts. Exact figures can vary by market and specific trim, so it’s best to confirm with the owner’s manual or the under-hood data plate.
Engine variants and their oil capacities
The Cruze lineup for 2018 included two main engines in many markets. The following summarizes the official capacities for these engines, quoted with the oil filter installed.
- Gasoline 1.4L turbo: approximately 4.2 quarts (with filter).
- Diesel 1.6L: approximately 5.0 quarts (with filter).
These figures reflect the capacities used when performing a standard oil change with the filter replaced. If you’re using a different variant or intent on a complete drain-and-fill, the total may differ slightly depending on the exact engine version and whether a new filter is installed.
Why the numbers vary
The difference in capacity stems from engine design, oil pan sizing, and whether the service procedure includes replacing the filter. Always verify the exact specification for your specific vehicle by consulting the owner's manual or the service data plate under the hood.
Maintenance guidance
When performing an oil change, use the recommended viscosity for your engine and climate (often 5W-30 for many GM engines) and replace the oil filter. After adding oil, recheck the level with the dipstick and avoid overfilling, which can cause engine issues.
Summary
The 2018 Chevy Cruze’s oil capacity varies by engine: about 4.2 quarts for the common 1.4L turbo gasoline engine and about 5.0 quarts for the 1.6L diesel. Always confirm the exact figure for your vehicle from the owner's manual or the data plate, as discrepancies can occur across markets and trims.
