For a 2015 Honda Accord, the recommended oil is 0W-20 full synthetic motor oil that meets API SN or newer. This grade applies to both the 2.4L four-cylinder and the 3.5L V6 engines in that model year.
Oil type and specifications
The 2015 Accord uses the same viscosity and quality standard across its available engines. Below is the official guidance you should follow when selecting oil for this car.
- Viscosity: 0W-20
- Oil type: Full synthetic (Honda recommends a full-synthetic formulation, though brands that meet the spec are acceptable)
- Certification: API SN or newer
In short, use 0W-20 full synthetic oil that meets API SN or newer, aligned with Honda’s guidance for both engines in the 2015 Accord.
Oil capacity by engine
Oil capacity varies by engine so you’ll want the right quantity when performing a change. The figures below assume a standard filter replacement.
- 2.4L inline-4: about 4.5 quarts (with filter)
- 3.5L V6: about 5.5 quarts (with filter)
Tip: After adding oil, let the engine rest for a few minutes, then recheck with the dipstick to ensure the level sits within the proper range.
Oil change interval and maintenance guidance
Maintenance schedules are delivered via Honda’s Maintenance Minder system and depend on driving conditions. General expectations with 0W-20 synthetic oil are as follows, though your car’s minder may differ:
- Normal driving: about every 7,500 miles or 12 months, whichever comes first
- Severe driving (frequent short trips, extreme temperatures, heavy traffic, towing): about every 3,750–5,000 miles or 6 months
For the most accurate interval, rely on the vehicle’s Maintenance Minder and your manual. These sources tailor service needs to your actual driving patterns.
Brand options and purchasing tips
When selecting a brand, you can stick with Honda Genuine Motor Oil or choose a reputable third-party full-synthetic 0W-20 that meets the API SN or newer specification.
- Honda Genuine Motor Oil 0W-20
- Other reputable brands offering 0W-20 API SN or newer formulations
Ensure the product is labeled 0W-20 and API SN or newer, and verify regional packaging or catalog details to match your vehicle’s requirements.

The 2015 Honda Accord calls for 0W-20 full synthetic motor oil that meets API SN or newer for both the 2.4L four-cylinder and the 3.5L V6 engines. Oil capacity is approximately 4.5 quarts for the 2.4L and about 5.5 quarts for the 3.5L, including the filter.
