How to verify the correct size for your car
To ensure you have the right plug size before attempting an oil change, follow these steps. The goal is to prevent cross-threading or stripping the oil pan.
- Check the owner’s manual or Honda service data for the exact drain plug specification for your engine variant.
- Inspect the underside of the oil pan to identify the head size and any markings on the plug.
- Test-fit a 14 mm socket; if it fits snugly, the head is 14 mm. If it doesn’t fit, try the next common sizes (12 mm or 17 mm) to avoid forcing.
- If replacing, use an OEM drain plug with the correct thread pitch and a new washer or seal as required by Honda spec.
- Torque the plug to the manufacturer’s specification using a torque wrench to avoid over-tightening or leaks.
Conclusion: For most 2013 Accord engines, you’ll start with a 14 mm head and M14 x 1.5 thread, but verify with official documentation or by checking the actual plug on the vehicle.

In short, the oil drain plug on a 2013 Honda Accord is typically a 14 mm head with M14 x 1.5 thread. This generally applies to both the 2.4L I-4 and the 3.5L V6, but variations can occur by engine variant or regional specifications.
