Most 2004 Civics that use the common 1.7-liter engine take about 3.4 quarts of oil with a filter. The 2004 Civic Si, which uses a 2.0-liter engine, requires roughly 4.5 quarts. To be sure, check your owner's manual or the under-hood label for your exact configuration.
Engine options and typical oil capacities
The 2004 Civic lineup included a 1.7-liter engine in most trim levels and a 2.0-liter engine in the Civic Si. The oil capacity varies by engine and whether you’re changing the filter. Use these figures as a guide and verify with official documentation for your specific VIN.
- 1.7-liter non-Si engine (DX/LX/EX): about 3.4 quarts with filter
- 2.0-liter Si engine: about 4.5 quarts with filter
Note: Capacities are for an oil change that includes replacing the filter. If you don’t replace the filter, you’ll use slightly less oil.
How to confirm the exact amount for your car
Because the Civic was offered with multiple engines in 2004, the precise oil capacity depends on your model and production year. Here are the steps to confirm the exact figure for your car:
- Check the owner's manual section on engine oil, which lists capacities by engine and service type.
- Look under the hood for a sticker near the radiator or hood latch that shows oil capacity and recommended grade.
- Find your engine code (D17 for 1.7L or K20 for 2.0L Si) on the engine block or VIN plate to identify the correct capacity.
- If in doubt, contact a Honda dealer or use the Honda service portal with your VIN for the exact specification.
Having the exact capacity ensures you add the right amount, avoiding underfilling or overfilling, which can affect engine performance and emissions.
Recommended oil type and grade
For most 2004 Civics, Honda recommends 5W-20 grade for peak performance and fuel efficiency, though some climates may permit 0W-20 or 5W-30. Always verify the grade listed in your manual or on the under-hood label for your region.
Summary
In general, a 2004 Honda Civic with the 1.7-liter engine takes about 3.4 quarts of oil with the filter, while the 2.0-liter Civic Si requires about 4.5 quarts. Confirm exact capacity for your specific model using the owner's manual, under-hood sticker, or VIN-based information from Honda. Use the correct oil grade (commonly 5W-20) and recheck levels after allowing it to settle.
