About 4.4 quarts of engine oil with a new filter for an oil change on the 2008 Civic's 1.8-liter engine.
For accuracy during maintenance, verify the fill using the dipstick and use Honda-recommended oil grade, typically 5W-20, adjusting for climate as needed. The exact amount can vary slightly depending on filter and drainage, so aim to reach the proper level after refilling.
Oil capacity specifics
The 1.8 L i-VTEC engine in the 2008 Civic lists an oil capacity of roughly 4.4 quarts (with filter) for a complete oil change. This is the standard volume required to fill the engine after a full drain when a new filter is installed.
Why the number can vary
Small differences in the total added oil can occur due to the exact filter size, how completely the oil is drained, and how much oil remains in the filter before installation. Always rely on the dipstick to confirm the correct level.
Oil grade and climate considerations
Honda typically specifies 5W-20 engine oil for the 1.8 L Civic in most regions. In extreme temperatures or as directed by the owner's manual, you may use a different grade, such as 5W-30. Always follow the manual and the cap label for the recommended grade.
Practical oil-change steps
When performing an oil change, start with about 4.4 quarts, run the engine briefly to circulate the oil, turn it off, and then recheck the level with the dipstick. Add small amounts as needed to bring the level to the correct range on the dipstick.
Summary
The 2008 Honda Civic 1.8 L typically requires around 4.4 quarts of engine oil when performing a full oil change with a new filter. Use the recommended 5W-20 oil and verify the final level with the dipstick, adjusting as necessary to reach the proper mark.
