The Civic Si typically takes about 4.7 quarts of engine oil when changing the oil and replacing the filter. This figure reflects the capacity of the modern 1.5-liter turbocharged engine used in current Si models and provides a reliable baseline for planning supplies.
That capacity can vary slightly by model year and configuration. The precise amount for your specific car should be confirmed in the owner's manual or on the under-hood oil capacity sticker, especially if you’re using a different filter or performing an unusually thorough change.
Oil capacity by era
The most common current Civic Si uses the 1.5L turbo engine, with a typical oil capacity around 4.7 quarts when the filter is installed. Older Civic Si models used different engines, and capacities varied; always verify the exact figure for your year.
- 2017–present Civic Si (1.5L turbo): 4.7 quarts with the oil filter installed.
- Older Civic Si models (pre-2017): engine and capacity varied by configuration; consult the owner's manual for the precise oil capacity.
As a practical note, many owners keep around five quarts on hand to comfortably complete a full change, including filter replacement and minor top-offs.
Oil type and maintenance guidance
Beyond capacity, using the correct oil type and following proper maintenance intervals are essential for reliability and performance. For the Civic Si, Honda typically specifies a 0W-20 synthetic oil, used in conjunction with a new oil filter at every change. Follow the vehicle’s Maintenance Minder system to determine when to service; intervals vary by driving conditions and model year.
- Recommended oil: 0W-20 synthetic (Honda Genuine or equivalent) for the Civic Si.
- Oil filter: Replace with every oil change.
- Maintenance intervals: Rely on the Maintenance Minder and the owner's manual for exact timing, as recommendations can vary by year and driving conditions.
Do-it-yourself oil change: a step-by-step guide
If you’re planning to change the oil yourself, here is a general, step-by-step guide to help you get it done safely and correctly.
- Gather supplies: 4.7 quarts of 0W-20 synthetic oil, an appropriate oil filter, a drain pan, a funnel, a wrench for the drain plug, a jack or ramps, and rags.
- Warm the engine slightly so the oil flows more easily, then park on a level surface and engage the parking brake.
- Lift the front of the car if needed and place the drain pan underneath the oil pan.
- Remove the drain plug and allow the old oil to drain completely into the pan.
- Remove the old oil filter, take care to catch any dripping oil, and prepare the new filter for installation (usually light lubrication on the gasket).
- Replace the drain plug securely, then pour the new oil into the engine using a funnel. Add about 4.7 quarts to start, then check the level with the dipstick and top up as needed to reach the full mark.
- Start the engine, idle briefly, check for leaks, recheck the oil level, and reset the Maintenance Minder if needed.
These steps provide a general framework. If you’re unsure or comfortable with vehicle maintenance, consider having a professional perform the service to ensure proper torque on the drain plug and correct oil level.
Summary
The Honda Civic Si typically requires about 4.7 quarts of engine oil with the filter installed, though exact capacity can vary by year and configuration. Use 0W-20 synthetic oil, replace the filter with each change, and rely on the Maintenance Minder to guide service intervals. Always confirm the exact specifications for your specific model year in the owner's manual or on the under-hood sticker, and follow proper safety procedures if you perform the change yourself.
