The 2012 Honda Accord uses 5W-20 engine oil. Both the 2.4-liter four-cylinder and the 3.5-liter V6 models require this viscosity, and you can use synthetic, synthetic blend, or conventional oil as long as it meets industry standards. The approximate oil capacities are about 4.5 quarts for the four-cylinder and about 5.7 quarts for the V6.
Oil type and specifications
For the 2012 Accord, the recommended viscosity is 5W-20. Oils should meet current API service standards and ILSAC ratings; most drivers use synthetic or synthetic-blend formulations to maximize protection and change intervals. The same viscosity applies to both engines in this model year, but always verify against the owner's manual or under-hood oil label for your specific vehicle.
Before listing the main points, note the following:
- Viscosity: 5W-20
- Oil types: synthetic, synthetic blend, or conventional (with appropriate change intervals)
- Standards: API service latest version and ILSAC GF-5 or newer
In summary, use 5W-20 oil that meets standard API/ILSAC specifications; choose synthetic or synthetic blend for better protection, or conventional if you’re constrained by budget, while keeping to the recommended change interval.
Oil capacity by engine
Knowing how much oil your engine holds helps ensure you don’t underfill or overfill after a change. The capacities below assume a filter change is included.
- 2.4L inline-4: approximately 4.4–4.5 quarts (with filter)
- 3.5L V6: approximately 5.5–5.7 quarts (with filter)
After adding oil, recheck the level with the dipstick and adjust to the full-mark as needed. Always use the correct oil type and viscosity when topping up.
Oil change intervals
Interval recommendations vary by oil type and driving conditions. The following guidelines reflect typical factory recommendations for the 2012 Accord:
- With synthetic oil (5W-20): about every 7,500 miles or 12 months, whichever comes first
- With conventional oil: about every 5,000 miles or 6 months, whichever comes first
In practice, severe driving conditions (short trips, extremely hot or cold climates, towing) may warrant shorter intervals. Always refer to the maintenance minder and the owner's manual for your exact schedule.
Summary
For a 2012 Honda Accord, use 5W-20 engine oil that meets API SN or newer and ILSAC GF-5 standards. Both the 2.4L and 3.5L engines share this viscosity. Oil capacities are roughly 4.5 quarts for the four-cylinder and 5.7 quarts for the V6, with change intervals typically around 7,500 miles with synthetic oil and 5,000 miles with conventional oil. Always confirm with the owner’s manual and monitor the oil level with the dipstick after each change.
