The engine oil drain bolt itself is very strong. It's the threads in the aluminum oil pan that are easier to strip. Recommended torque is 22 ft-lb...As for torguing the drain plug..... Hmm, I torque most drive train bolts, but I use the by hand guessing method for drain plugs. I've stripped these before and it's no fun.
It's a plug, not a hardened bolt holding moving parts together.
