The 2020 Civic’s oil capacity depends on the engine: 3.1 quarts for the 2.0-liter inline-4 and about 4.2 quarts for the 1.5-liter turbo, both with the oil filter installed.
The question reflects that Honda offered two engines in the 2020 Civic, each with its own lubrication requirements. The 2.0L engine uses 3.1 quarts of engine oil (with filter) and the 1.5L turbo uses roughly 4.2 quarts (with filter). The recommended oil type is typically 0W-20 full synthetic in most markets. Always verify exact figures in your owner’s manual or with a Honda dealer, as capacities can vary by market or model year specifics and including or excluding certain components can change the total required.
Engine options and oil capacities
The following figures come from official Honda service materials and the 2020 Civic owner's manual.
- 2.0-Liter Inline-4 (non-turbo): oil capacity 3.1 quarts with filter
- 1.5-Liter Turbocharged (Sport, EX, Touring trims): oil capacity about 4.2 quarts with filter
Note: Some markets and model variants may show slight differences; if your vehicle has a different configuration or aftermarket parts, check the exact capacity in the manual.
Additional considerations
When performing an oil change, also replace the oil filter, use the recommended viscosity (usually 0W-20 full synthetic), and properly dispose of used oil. After filling, run the engine, turn it off, wait a few minutes, and recheck the oil level with the dipstick to ensure it's within the correct range.
Summary
For the 2020 Honda Civic, the engine oil capacity is 3.1 quarts for the 2.0L engine and about 4.2 quarts for the 1.5L turbo, with the filter included. Use 0W-20 full synthetic oil and verify exact figures in your manual or with a dealer. Always perform oil changes according to the recommended schedule and recheck the level after the engine has cooled.
