Once the oil has slowed to a drip, wipe off the area around the drain plug with a clean rag or towel.

Reinstall the drain plug and tighten it with a box end wrench until it is snug. Alternatively, you can use a torque wrench to verify that the plug is tightened to spec. The torque spec for the drain plug is 29 ft./lbs. (39 Nm)

Do not over-tighten the drain plug. You may risk stripping the threads or cracking the oil pan. It's better that it be too loose, rather than too tight, because you can always go back later and tighten it. If in doubt, verify the torque using a torque wrench.
