The 2010 Civic’s oil capacity depends on the engine: about 4.5 quarts for the 1.8-liter model, and roughly 4.7–4.8 quarts for the 2.0-liter Si.
In more detail, oil capacity varies between trims because the LX/EX/EX-L models use the 1.8 L engine, while the high-performance Si uses a larger 2.0 L unit. Always verify the exact capacity for your vehicle in the owner's manual or on the under-hood oil-fill sticker to ensure a correct full-change fill.
Engine options and their oil capacities
The figures below reflect the typical oil capacities for the two primary engine variants in the 2010 Civic lineup. Use them as a guide, but confirm with official documentation for your specific car.
- 1.8 L i4 (R18A1): about 4.5 quarts of oil with a new filter
- 2.0 L i4 (K20Z3) in the Civic Si: about 4.7–4.8 quarts of oil with a new filter
These numbers account for the oil filter capacity as part of a standard full change. When topping off between changes, check the dipstick to bring the level to the correct range.
Maintenance tips and verification
Why capacity varies by engine
The difference stems from each engine’s oil pan size, filter volume, and Honda’s design specifications. The Si’s 2.0 L engine typically requires a slightly larger fill to reach the proper level after a full change.
Always use the recommended viscosity and oil specification (commonly 5W-20 for 2010 Civics) and the correct OEM oil filter. After changing the oil, run the engine, stop it, wait a few minutes, and recheck the level on the dipstick to ensure it’s within the specified range.
Summary
For the 2010 Honda Civic, oil capacity depends on the engine. The 1.8L version takes about 4.5 quarts with a filter, while the 2.0L Si version takes roughly 4.7–4.8 quarts. Always verify against the manual or under-hood sticker and use the proper filter and oil grade for an accurate fill. Regular maintenance helps keep the Civic running smoothly.
