The vast majority of 2012 Honda engines use a 14mm hex drain plug with an M14x1.5 thread, but there are model- and engine-specific exceptions. Always verify against your exact vehicle's manual or with a dealer.
Context and scope
Honda’s 2012 lineup spans several models and engine options, from the Civic and Accord to the CR-V and Fit. While many share a common drain plug size, variations do exist depending on the engine code and market. This article outlines the typical size and how to confirm yours.
Common sizing across popular 2012 Honda models
Below is a quick reference for the drain plug size that technicians most often encounter on well-known 2012 Honda passenger cars. Use this as a starting point, but verify for your exact engine code.
- Honda Civic (2012, 1.8L) – 14mm hex socket; thread: M14x1.5
- Honda Accord (2012, 2.4L) – 14mm hex socket; thread: M14x1.5

Note: Some 2012 Honda models with different engines or regional specifications may deviate from this pattern. If the plug doesn’t fit a 14mm socket, consult the service manual or check with a dealer to confirm the exact size and pitch for your vehicle.
How to verify the plug size yourself
For those who want to confirm without pulling parts, these methods help ensure you have the right size before an oil change.
- Check the owner’s manual or service manual for your exact engine code and vehicle trim; the drain plug size and torque are typically listed there.
- Remove the drain plug (carefully) and test a 14mm socket; if it doesn’t fit, try a 12mm or 17mm, and measure the hex to identify the correct size.
- Take a photo of the plug and reference it with a Honda parts catalog or ask your local dealer using your VIN for the precise specification.
Always replace the crush washer and adhere to the recommended torque. If in doubt, seek guidance from a professional technician or the dealer to confirm the correct size for your exact model and engine.
Maintenance tips related to the drain plug
- Use the proper drain plug size and crush washer to ensure a reliable seal and prevent leaks.
- Replace the crush washer at every oil change.
- Dispose of used oil responsibly and follow local regulations.
Sticking to the manufacturer’s guidance minimizes the risk of cross-threading and leaks, and it helps extend the life of the engine oil system.
What to do if you can’t locate the manual
If the manual isn’t available, contact a Honda dealership or a trusted auto parts retailer with your VIN. They can confirm the exact drain plug size for your 2012 model and engine variant, and help with the correct washer and torque specs.
Conclusion and takeaway
For most 2012 Honda vehicles, the oil drain plug is a 14mm hex with an M14x1.5 thread, paired with a crush washer. However, exact sizes can vary by model and engine, so always verify with the owner’s or service manual or by consulting a dealer. Correct sizing helps prevent leaks and cross-threading during oil changes.
Summary: The typical drain plug size on 2012 Honda models is 14mm (M14x1.5) with a crush washer, but always check your specific model and engine to be certain.
