On a 2018 Honda Civic, engine oil capacity depends on the engine under the hood. The 1.5-liter turbo models typically require about 3.1 quarts of oil during an oil change (roughly 3.0 liters), while the 2.0-liter engines call for about 4.5 quarts. Always consult the owner’s manual or service guide for the exact figure for your VIN and whether the filter is included in the change.
Engine options and oil capacity
1.5L turbocharged engine (L15B7)
Oil capacity figures for the 1.5L turbo engine are commonly cited by service guides as follows:
- 3.1 quarts (approximately 3.0 L) without replacing the filter
- 3.4 quarts (approximately 3.2 L) with a new filter
Note: Actual capacity may vary slightly by production batch and whether a filter is replaced. Always confirm with the owner's manual.
2.0L engine (K20C2)
Oil capacity for the 2.0L engine is typically:
- 4.5 quarts (approximately 4.3 L) with the filter included in an oil change
As with the 1.5L engine, verify the exact figure for your vehicle and perform a dipstick check after adding oil to ensure proper level.
Maintenance notes
Practical tips for accurate oil levels: use the recommended viscosity (often 0W-20 for Civics), add oil gradually, wait a few minutes for the oil to settle, and then recheck with the dipstick. If you’re unsure, have a qualified mechanic confirm the capacity for your specific model and trim.
Summary
The 2018 Honda Civic’s oil capacity varies by engine: around 3.1 quarts for the 1.5L turbo and about 4.5 quarts for the 2.0L engine, with the filter considerations noted above. Always cross-check the owner’s manual and perform a dipstick check after adding oil to ensure you reach the correct level.
