Short answer: about 4.5 quarts (roughly 4.3 liters) of engine oil with a filter during a full oil change.
The 2009 Honda Accord with a 2.4-liter engine uses Honda’s K-series four-cylinder design. While 4.5 quarts is the standard figure for a complete drain-and-fill with a new filter, the exact amount can vary slightly depending on trim, production batch, and whether you replace the oil filter. The guidance below outlines the official capacity and practical tips for performing the change.
Oil capacity specifications
Below are the typical capacities you’ll encounter when performing a full oil change with a new filter. If you’re topping off, use these figures as a reference and confirm with the dipstick while the engine is cool.
- With a new oil filter: about 4.5 quarts (approximately 4.3 liters).
- Without replacing the filter (drained oil, no filter change): about 4.0 quarts (roughly 3.8 liters).
Note: Some service references list a narrow range around 4.4–4.7 quarts due to production variance and measurement conventions. Always verify the final level with the dipstick and follow the owner’s manual for the exact specification for your vehicle.
Practical oil-change guidance
Recommended oil grade for most climates is 5W-20, though certain conditions or markets may call for different specifications. Check the owner's manual for the correct viscosity and service intervals. Use a quality oil filter and ensure the drain plug is tightened to the specified torque.
After completing the change, run the engine briefly, turn it off, wait a minute, and recheck the level on the dipstick. Top off if needed to reach the full mark.
Context and caveats
Oil capacity can vary slightly by exact engine variant within the 2.4 L family and by aftermarket filter choices. When using non-standard filters or different oil pans, confirm the total capacity with the service manual or a dealer.
Conclusion
For a 2009 Honda Accord with a 2.4 L engine, plan on roughly 4.5 quarts of oil for a full change with a new filter. Variations are possible, so rely on the dipstick for the final verification and consult your owner's manual for precise guidance.
Summary
The 2.4 L four-cylinder engine in the 2009 Honda Accord typically requires about 4.5 quarts (4.3 liters) of engine oil for a complete oil change with a new filter, with minor variations depending on exact configuration and service practices. Always confirm the final level with the dipstick and follow the manual for oil grade and change intervals.
