The 2009 Honda Accord typically requires 5W-20 engine oil for its main engines, with specifications that match API SN or newer and ILSAC GF-4/5. Always verify exact requirements in the owner’s manual or on the under-hood label for your specific model and region.
In practice, most U.S.-spec 2009 Accords use about 4.7 quarts of oil for the four-cylinder engine and roughly 5.7 quarts for the 3.5-liter V6 when replacing the filter. Both conventional and synthetic oils are acceptable as long as they meet the stated specifications. Climate and driving conditions can influence the choice of oil type and change intervals, so consult the manual for your situation.
Oil viscosity and specifications
Key guidelines to follow when selecting oil for the 2009 Accord are summarized here.
- Viscosity: 5W-20 is the recommended oil grade for both the 2.4L four-cylinder and the 3.5L V6 engines in most markets.
- Alternative when 5W-20 is unavailable: If 5W-20 cannot be found, 5W-30 may be used as a temporary substitute, but return to 5W-20 as soon as possible per Honda guidance.
- Specifications: Use oil that meets API SN (or newer) and ILSAC GF-4 or GF-5 specifications; look for "Energy Conserving" on the label.
- Oil type: Acceptable options include conventional, synthetic blend, or full synthetic, as long as the above specs are met.
- Capacity: 4-cylinder engine holds about 4.7 quarts (with filter); 6-cylinder holds about 5.7 quarts (with filter).
In practice, always confirm the exact capacity and required grade for your specific vehicle using the owner’s manual or the door jamb/hood sticker, as there can be regional differences.
Practical maintenance notes
Beyond selecting the right oil, consider how you perform oil changes and monitor levels to maintain engine health.
- Change interval guidance: If you use conventional oil, expect roughly 5,000 miles (or 6 months) between changes; with synthetic or synthetic blend, intervals commonly extend to 7,500–10,000 miles, but always follow the maintenance minder and manufacturer recommendations.
- Oil filter and disposal: Replace the oil filter with a genuine Honda part or equivalent; dispose of used oil at an authorized recycling facility.
- Quality brands: Choose from Honda Genuine Motor Oil or other brands that meet API SN/ILSAC GF specs and are labeled Energy Conserving.
Correct maintenance includes following the car’s maintenance minder system when available and adhering to the manual-specified intervals to ensure optimal protection and efficiency.

If 5W-20 is unavailable, 5W-30 can be used temporarily, but revert to 5W-20 as soon as possible. Oil capacity ranges from about 4.7 quarts for the four-cylinder to roughly 5.7 quarts for the V6, with a compatible oil filter. Always verify exact requirements in the owner's manual or on the under-hood label for your specific vehicle and region.
