About 4.5 quarts of engine oil are required for a full oil change with a new filter.
The 2014 Honda Civic Si uses a 2.4-liter K-series engine and Honda’s specification calls for synthetic 0W-20 oil. The official oil capacity is 4.5 quarts with the filter. Always verify the exact specification in your owner's manual and by checking the dipstick after filling, as regional variations can apply.
Official oil capacity and recommended oil
Here are the key capacity and oil-spec notes for the 2014 Civic Si.
- Oil capacity (with filter): 4.5 quarts (about 4.3 liters).
- Recommended oil: Synthetic 0W-20 (API SN or newer).
- Note: After adding oil, always check the level with the dipstick and adjust as needed to reach full when the engine is warm.
In practice, use the dipstick to verify full after filling; the filter adds volume, which is why the 4.5-quart figure is specified for a standard change.
Practical tips for changing the oil
Before performing an oil change, gather the right parts and follow the steps to ensure an accurate fill and proper lubrication.
- Use 0W-20 full-synthetic oil; confirm the grade is appropriate for your market from the manual.
- Use a compatible oil filter designed for the 2014 Civic Si (Honda-part or equivalent).
- Warm the engine slightly to help draining, then replace the drain plug and oil filter before adding new oil.
Always consult the owner's manual or a qualified technician if you are unsure, as regional differences can influence the exact specification.
Summary
For a 2014 Honda Civic Si, plan on adding 4.5 quarts of engine oil when performing a full oil change with a new filter, using 0W-20 synthetic oil. Verify the final level with the dipstick after startup and let the engine run briefly to distribute the oil, then recheck for accuracy.
