The Civic EX with a 1.8-liter engine uses about 4 quarts of engine oil when you perform an oil change, including the filter.
For context, the 2015 Civic EX typically requires 0W-20 synthetic oil, and the official capacity is 4.0 quarts with the filter installed. Without the filter, the total capacity is around 3.7 quarts. Always verify your exact figure in the owner's manual or Honda's official specs for your vehicle's VIN and market.

What you need to perform an oil change
As you prepare, assemble tools and supplies to ensure a smooth change.
- 0W-20 synthetic oil (about 4 quarts with filter)
- New oil filter compatible with the 1.8-liter engine
- Oil drain pan and funnel
- Socket wrench set and drain plug gasket (if needed)
- Jack stands or ramps for elevation, and gloves
- Rags and a method to dispose of used oil responsibly
Having the right parts and tools on hand minimizes the risk of spills and ensures a complete, safe oil change. Always recycle used oil at an authorized facility.
Oil change steps for a 2015 Civic EX
Follow these general steps to change the oil and replace the filter efficiently.
- Warm up the engine briefly, then park on a level surface and engage the parking brake.
- Lift the front of the car and support securely on ramps or stands.
- Place the drain pan under the oil drain plug, then remove the plug and allow the old oil to drain completely.
- Remove the old oil filter, taking care of any residual oil; install the new filter per the orientation specified by Honda.
- Reinstall the drain plug with a new gasket if required and torque to factory specification.
- Fill with 4.0 quarts of 0W-20 oil using a funnel, then replace the oil fill cap.
- Start the engine, let it run for a minute, then turn it off and check the oil level with the dipstick, adding more if needed to reach the full mark.
- Dispose of the used oil and filter properly according to local regulations, and reset oil-change indicators if applicable.
Note: Depending on your vehicle’s condition, you may need slightly more or less oil. Always check the level and consult the manual for torque specs and filter type. If you’re uncomfortable performing an oil change, have a professional service the vehicle.
