In most cases, the 2009 Honda Accord requires about 4.4 quarts of engine oil for the 2.4-liter four-cylinder version, and roughly 5.5 to 5.7 quarts for the 3.5-liter V6. Always verify with your owner’s manual and use the recommended viscosity for your climate and driving conditions.
Engine options in the 2009 Accord
The 2009 Accord was offered with two gasoline engines: a 2.4-liter inline-four and a 3.5-liter V6. Oil capacity depends on the engine type and whether you replace the oil filter during a full change. Identifying your engine can help ensure you use the correct quantity and oil specification.
Identifying your engine
Check the engine code on the engine cover or consult your vehicle’s VIN details in the owner’s manual or through a Honda dealership if you’re unsure which engine your car has.
Oil capacity by engine
Note: The following figures assume you replace the oil filter. Capacities can vary slightly by model year and market. Always confirm with the dipstick after filling.
- 2.4-liter four-cylinder: about 4.4 quarts (4.2 liters) with a new filter; roughly 4.0 quarts (3.8 liters) if you do not replace the filter.
- 3.5-liter V6: about 5.5–5.7 quarts (5.2–5.4 liters) with a new filter; around 5.0 quarts (4.7 liters) if you skip the filter change.
When you complete an oil change, start the engine, let it run briefly, and recheck the level with the dipstick. Do not overfill, as excess oil can cause increased pressure and engine issues.
Oil type and filling procedure
Honda generally recommends 5W-20 engine oil for the 2009 Accord across both engines, though regional specifications may vary. Use the recommended oil grade and a genuine Honda oil filter. If you’re switching from conventional to synthetic or changing brands, follow the manufacturer’s guidance for a smooth transition and optimal protection.
- Park on level ground and warm the engine slightly or let it sit for a few minutes after a brief idle to loosen oil.
- Lift the front of the car securely and place a container beneath the drain plug.
- Drain the old oil by removing the drain plug and allow all oil to flow out.
- Remove and replace the oil filter with a new one, ensuring a proper seal.
- Reinstall the drain plug and pour in a portion of the recommended oil, gradually adding until you reach the target capacity noted for your engine.
- Run the engine for a few minutes, turn it off, and wait a few minutes for the oil to settle, then recheck the level with the dipstick and top off if needed.
- Dispose of the used oil and filter according to local regulations.
Following these steps helps ensure a clean oil change without overfilling and maintains proper engine lubrication.
Maintenance tips
To keep the engine in good condition, keep these practices in mind:
- Use the correct OEM oil filter and the manufacturer-recommended viscosity and quantity.
- Record the date and mileage of each oil change to stay on top of maintenance intervals.
- Inspect for leaks around the filter, drain plug, and oil pan after changes.
Regular maintenance, including timely oil changes, helps protect the engine and preserve fuel efficiency and performance over the life of the vehicle.
Summary
The 2009 Honda Accord requires about 4.4 quarts of oil for the 2.4L four-cylinder and about 5.5–5.7 quarts for the 3.5L V6, with the exact amount depending on whether you replace the oil filter. Use the recommended 5W-20 oil for most conditions, confirm with the owner's manual, and follow proper filling and disposal procedures to ensure optimal engine health.
