The 2015 Accord requires about 4.5 quarts of engine oil for the 2.4-liter four-cylinder, or 5.7 quarts for the 3.5-liter V6, with a filter installed. Verify your engine type to confirm the exact amount.
Oil capacity depends on the engine option, and exact figures can vary by market and vehicle configuration. This article explains the standard capacities and how to check and top off oil correctly after a change.
Oil capacity by engine
These figures reflect typical factory specifications for the U.S.-spec 2015 Honda Accord, assuming a full oil change with a new filter. Always consult your owner's manual or the under-hood label for the precise requirement for your VIN.
- 2.4 L four-cylinder engine: 4.5 quarts (with filter)
- 3.5 L V6 engine: 5.7 quarts (with filter)
If you’re unsure which engine your car uses or if your vehicle has regional variations, double-check the manual or the exact specifications printed on the engine block or oil cap label.
How to check and top off oil
Use these steps to verify and adjust the oil level after a change or top-up, ensuring proper fill without overdoing it.
- Park on level ground, engage the parking brake, and turn off the engine. Wait several minutes for oil to settle.
- Open the hood, pull the dipstick, wipe it clean, reinsert, and pull it out again to read the level.
- If the level is below the Full mark, add oil in small increments (about 0.25 quart) and recheck after the oil has circulated.
- Repeat until the dipstick shows the level within the acceptable range—do not exceed the Full mark.
- Once correct, reinsert the dipstick, close the hood, and run the engine briefly to ensure oil is circulating, then recheck if needed.
Always use the recommended viscosity and a quality oil and filter. If you’re unsure about the correct grade for your market, consult the owner's manual or a qualified technician.
Summary
For the 2015 Honda Accord, oil capacity depends on the engine: about 4.5 quarts for the 2.4L four-cylinder and about 5.7 quarts for the 3.5L V6, both with a new filter. Confirm your engine type and refer to the owner’s manual or under-hood label for the exact specification and oil viscosity guidance. Properly checking and topping off oil helps maintain engine health and performance.
