Wipe down the area around the drain plug with a clean rag or towel.

Reinstall the drain plug and tighten it as much as you can by hand.

Use a 17 mm box end wrench to tighten the drain plug until it is snug.

Do not over-tighten the drain plug. Doing so may strip the threads or crack the oil pan. You can always come back later and tighten the drain plug more if needed.
