How To Use WD-40 To Remove Oil Drain Plug?

To use WD-40 to remove an oil drain plug, follow these steps:

  • Make sure the engine is cool before starting. If you recently ran your vehicle, give it time to cool down to avoid burns.
  • Get a can of WD40 and a suitable wrench or socket set that fits the oil drain plug.
  • Shake the can of WD-40 well, then spray a generous amount onto the oil drain plug. Focus on spraying around the base of the plug and where it connects to the oil pan.
  • Allow a few minutes for the WD40 to penetrate and loosen any rust or debris.
  • Place the wrench or socket onto the oil drain plug and apply steady but gentle pressure in an anticlockwise direction (lefty-loosey). Be careful not to strip the bolt. If it’s challenging to turn, try using a breaker bar for additional leverage.
  • If the drain plug doesn’t budge, apply more WD-40 and allow it to sit for a few more minutes. This extra time will help penetrate further and loosen the plug.
  • Once the oil drain plug starts moving, turn it anticlockwise until it comes off completely. Do not drop the plug into the oil pan or onto the ground.
  • Inspect it for any damage or excessive wear once the plug is removed. If necessary, replace it with a new plug. Clean the plug with a rag or paper towel before reinstallation if the plug is reusable.

Important note: WD-40 is not a lubricant for reassembling the oil drain plug. It is primarily used for loosening and removing stuck or rusty parts. When reinstalling the drain plug, use an appropriate lubricant or thread sealer recommended by your vehicle manufacturer to ensure a proper seal.
