For a 2008 Honda Civic, oil capacity depends on the engine: about 4.4 quarts for the standard 1.8-liter engine, and about 4.5 quarts for the Civic Si’s 2.0-liter engine.
Engine options and oil capacity
The 2008 Civic lineup used two main engine options. The standard models run a 1.8-liter four‑cylinder, while the performance-oriented Civic Si uses a 2.0-liter engine. Each engine has a slightly different oil capacity, which is important to know when preparing for an oil change.
- 1.8-liter four-cylinder (R18A1): 4.4 quarts of oil with the filter.
- 2.0-liter four-cylinder (K20Z3, Civic Si): 4.5 quarts of oil with the filter.
When planning an oil change, consider the engine type to ensure you purchase the correct amount of oil and replace the filter. After adding oil, run the engine and recheck the level with the dipstick to confirm it’s within the proper range.
Practical notes and verification
Verifying your engine type
Check the vehicle’s VIN, under-hood label, or the owner’s manual to confirm which engine your 2008 Civic uses. The capacity listed here applies to the common configurations for that year, but trims or market variations can differ.
Oil type and final checks
Use the oil viscosity recommended in the owner's manual (typically around 5W-20 or 5W-30 for many 2008 Civics). Always use a new oil filter and avoid overfilling, which can cause oil foaming or pressure issues. After adding oil, recheck the level and ensure the engine runs briefly before performing a final level check.
Summary
In summary, the 2008 Honda Civic requires approximately 4.4 quarts of oil with a filter for the standard 1.8-liter engine and about 4.5 quarts with a filter for the Civic Si’s 2.0-liter engine. Always verify your exact engine type and consult the owner’s manual or the under-hood sticker, then confirm the final level with the dipstick after an oil change.
