What size socket for Honda oil plug?
The typical oil drain plug on most Honda cars uses a 14 mm socket. Some engines or models may require a 17 mm socket, so you should verify for your specific vehicle.
Oil changes rely on the correct tool to avoid damaging the plug or threads. This guide explains which sizes you’re likely to encounter and how to confirm the right size for your Honda.
Common socket sizes you may encounter
Because Honda uses multiple drain plug designs over the years, you’re most likely to need either a 14 mm or a 17 mm socket.
- 14 mm socket/hex: The most common size for many Honda engine oil drains.
- 17 mm socket/hex: Some engines and newer models may require this size; verify with your manual or inspect the plug head.
Having both sizes on hand and tightening to the manufacturer’s torque specification helps prevent stripping the plug and ensures a proper seal.
How to confirm the correct size for your model
Use these steps to confirm the correct drain plug size for your specific Honda model before you start the oil change.
- Check the owner's or service manual for the exact drain plug size and torque specification for your engine.
- Inspect the drain plug head to identify whether it’s a standard hex (socket) or a different profile such as 12-point; this affects which tool you use.
- If you’re unsure, try the 14 mm size first, then the 17 mm if the 14 mm does not seat securely. Do not force a socket onto the plug.
Confirming the correct size protects the threads and ensures a safe, leak-free oil change.
Additional tips for Honda oil changes
Beyond socket size, ensure you have the right oil type and viscosity for your engine, the proper oil filter, and any required washers or gaskets as specified by Honda for your model year. Torque is important; always tighten to the labeled specification.
Summary
For most Honda passenger cars, expect a 14 mm drain plug socket; a 17 mm socket is used on some models. Always confirm with the owner's manual or by inspecting the plug head and applying the recommended torque.
