What size socket is a car drain plug?

The size of the socket needed for a car's drain plug typically ranges from 10mm to 19mm, with the most common sizes being 14mm, 15mm, and 17mm. The exact size will depend on the make, model, and year of the vehicle.


Understanding Car Drain Plugs


The drain plug is a crucial component in a car's oil change process. It is located at the bottom of the oil pan and is used to drain the old oil from the engine. The size of the drain plug socket is an important consideration when performing an oil change, as using the wrong size can lead to damage or stripping of the plug.


Determining the Drain Plug Size



  • The most common drain plug sizes are 14mm, 15mm, and 17mm, but some vehicles may use smaller or larger sizes.

  • The size of the drain plug is typically stamped or engraved on the plug itself, making it easy to identify.

  • If the drain plug size is not visible, you can consult your vehicle's owner's manual or look up the information online based on the make, model, and year of your car.

  • It's important to use the correct socket size to avoid stripping the plug, which can be a costly and time-consuming repair.


Knowing the right drain plug size for your car is essential for a successful oil change. By using the appropriate socket, you can ensure a smooth and efficient oil change process.
