The engine holds about 4.5 quarts (4.3 liters) of oil when performing an oil change with the filter; about 4.0 quarts (3.8 liters) if you do not replace the filter.
For context, this applies to the 2004 Accord’s 2.4 L inline-four engine. Actual amounts can vary slightly based on the exact filter, drainage, and whether you’re topping off after an oil change. Always confirm with the dipstick after refilling.
Capacity basics
Before listing the typical fill quantities, note that the figures below reflect standard service practice for this engine family. Use them as a starting point and verify with a dipstick to reach the full mark.
- With oil filter change: 4.5 quarts (4.3 liters).
- Without changing the filter: about 4.0 quarts (3.8 liters).
Concluding guidance: when performing an oil change on the 2004 Accord 2.4 L, begin with 4.5 quarts of oil, then run the engine, let it settle, and top off as needed to reach the correct level on the dipstick.
Oil type and grade
Choosing the right oil grade and type helps ensure proper lubrication and engine protection. The 2.4 L engine in the 2004 Accord typically uses a 5W-20 viscosity as the standard recommendation, with 5W-30 acceptable in hotter climates or under certain severe-service conditions. Always consult the owner’s manual or a dealer for climate- and VIN-specific guidance.
Notes on oil specification
- Recommended viscosity: 5W-20 for most environments; 5W-30 can be used in hot climates or severe service as advised by the manual.
- Oil type: conventional or synthetic oils are acceptable, provided they meet ILSAC GF-5 (or newer) and API SN (or newer) specifications.
Concluding guidance: match the oil to the climate and follow the manual’s specifications for the best balance of protection and efficiency.
Practical change steps
If you’re performing an oil change, follow a standard, safe procedure to reach the correct capacity and ensure proper lubrication.
- Warm the engine briefly to loosen oil, then park on level ground and turn off the engine.
- Place a drain pan underneath, loosen and remove the drain plug, and allow the old oil to drain completely.
- Remove the old oil filter, install a new filter, and smear a little fresh oil on the gasket.
- Replace the drain plug securely, then pour in about 4.5 quarts of oil (with filter) to start.
- Start the engine and let it run for a minute; check for leaks and then turn it off.
- Wait several minutes for the oil to settle, then check the level with the dipstick and top off to the full mark if needed.
Concluding guidance: while 4.5 quarts is a solid starting point for a full oil change with a new filter, always verify the final level after the engine has rested and top off as necessary to the indicated mark.
Summary
The 2004 Honda Accord 2.4 L generally requires about 4.5 quarts (4.3 liters) of oil when changing the oil and filter, or about 4.0 quarts (3.8 liters) if the filter is not replaced. Use 5W-20 as the standard viscosity in most regions, with 5W-30 as an alternative in hot climates or per manual guidance. Always confirm the level with the dipstick after refilling and follow safe oil-change procedures to avoid overfilling or leaks.
