What size socket for oil drain plug?

The size of the socket needed for an oil drain plug can vary depending on the make and model of your vehicle. However, the most common sizes are 17mm, 19mm, and 22mm. To determine the correct size for your vehicle, it's best to consult your owner's manual or check the size of the existing drain plug.


Determining the Correct Socket Size


The size of the oil drain plug socket is typically determined by the diameter of the plug itself. This information can usually be found in your vehicle's owner's manual or by inspecting the existing plug. Some common socket sizes for oil drain plugs include:



  • 17mm: This is a common size for many smaller vehicles, such as compact cars and some motorcycles.

  • 19mm: This is a popular size for many mid-sized and larger vehicles, including sedans, SUVs, and trucks.

  • 22mm: This larger size is often found on heavy-duty trucks, vans, and some high-performance vehicles.


It's important to use the correct socket size to avoid stripping or damaging the plug. Using the wrong size can also make it difficult to remove the plug, potentially leading to frustration and additional time spent on the task.


Tips for Changing the Oil Drain Plug



  • Locate the drain plug: The oil drain plug is typically located at the bottom of the oil pan, near the front or rear of the vehicle.

  • Prepare the area: Place a drain pan underneath the plug to catch the used oil, and have a rag or paper towels on hand to clean up any spills.

  • Loosen the plug: Use the appropriate socket size to loosen the plug, turning it counterclockwise. Be careful not to overtighten it when reinstalling.

  • Dispose of the used oil properly: Once the oil has drained, replace the plug and tighten it securely. Dispose of the used oil at a designated recycling center or auto parts store.


Changing your vehicle's oil and replacing the drain plug is a routine maintenance task that can help extend the life of your engine. By using the correct socket size, you can ensure the job is done safely and efficiently.
