For a typical oil change, the primary wrench needed is a socket wrench used with the appropriate size socket for your vehicle's oil drain plug.
Based on the provided reference, you will likely need a socket wrench and a 3/8-inch (0.9 centimeters) socket. This socket is specifically mentioned for fitting over the drain plug's nut to loosen it.
Tools Needed for the Oil Drain Plug
While vehicles vary, removing the oil drain plug usually requires a socket wrench and a socket. The reference highlights a common size:
- Socket Wrench: This tool provides leverage to turn sockets.
- Socket: A specific size attachment that fits snugly over the drain plug's nut. The reference suggests using a 3/8-inch (0.9 centimeters) socket.
- Other potential tools: Depending on your specific car's oil filter type (cartridge or spin-on), you might also need an oil filter wrench.
Using the Socket Wrench and Socket
The process involves fitting the correct size socket onto the oil drain plug nut. As mentioned in the reference:
- Place a 3/8-inch (0.9 centimeters) socket in the socket wrench.

Why Socket Size Matters
The size of the drain plug nut varies between vehicle makes and models. Common sizes often range from 12mm to 19mm, or their SAE equivalents like 1/2 inch or 3/8 inch. Using the correct size socket prevents stripping the nut. A socket set is a valuable investment for car maintenance as it includes various sizes.
