The 2009 Honda Civic typically requires about 4.4 to 4.5 quarts of engine oil with a filter, depending on the engine. The 1.8-liter engine uses around 4.4 quarts, while the 2.0-liter engine used in the Si version takes about 4.5 quarts. Use 5W-20 oil as the standard viscosity, and check your owner's manual for any climate-specific allowances.
Oil capacity by engine
The Civic offered two engines in 2009, and each has a slightly different oil-fill requirement. The numbers below assume a standard oil change with a new filter.
- 1.8-liter inline-4 (LX/EX/DX): about 4.4 quarts (roughly 4.2 liters) with filter.
- 2.0-liter inline-4 (Si): about 4.5 quarts (roughly 4.3 liters) with filter.
These figures are approximate and may vary slightly by manufacturing specifications or if you are using a different filter size. Always verify the level with the dipstick after filling and fill to the Full line, not beyond, to avoid overfill.
How to add oil and check the level
Use the correct grade and the proper amount, then check the level carefully. Follow these steps to top off and confirm the oil is at the proper level.
- Run the engine briefly to warm the oil, then turn it off and wait about 5 minutes for the oil to settle.
- Open the hood and locate the oil filler cap on top of the engine and the dipstick near the engine front.
- Remove the filler cap, place a funnel, and add oil in small increments, checking the dipstick after each addition.
- Continue adding until the dipstick reads between the MIN and MAX marks, typically the Full mark when the engine is cold or at operating temperature depending on the dipstick design.
- Replace the filler cap securely, start the engine, and recheck the level after a few minutes to ensure it stays within the correct range.
Tip: Avoid overfilling; if you accidentally add too much, drain some out or use a syringe to remove excess oil. Also confirm you are using the right viscosity: 5W-20 is standard for most 2009 Civics; consult your manual if you live in extreme heat or cold where 0W-20 may be specified.
Summary
The 2009 Honda Civic’s oil capacity depends on the engine: about 4.4 quarts for the 1.8L and about 4.5 quarts for the 2.0L Si. Plan to use 5W-20 oil (or 0W-20 in climates where specified by Honda), change the oil filter at the same time, and always verify the final oil level with the dipstick after topping off.
