I just did my first oil change at 1372 mi and the oil drain plug came loose with like zero pressure on the wrench! Seriously, I just started to apply pressure with the socket wrench and it started to turn! No, I am not a body builder or strong guy. Anyone else note this?

I'm going to put a separate post re what I like to use for the torque wrench. 25 nm = 18 ft-lbs = 216 in-lbs is too little to even show on most 100 ft-lb torque wrenches and my inch-lbs wrench only goes to 200.

Mine was the same. I was surprised it wasn’t leaking

What drain plug tightening torque does BMW call for?

FWIW just to show you there is some variation in drain plug tightening torque, from the engine oil change section of my Porsche 996 Turbo:

Tighten the drain plug on the crankcase to 70 Nm (52 ftlb.) those on the oil container [tank] to 60 Nm (44 ftlb.), and the drain plugs on the turbocharger to 30 Nm (22 ftlb.).

The above is not to suggest you should use any of those values but use what BMW calls for.

I was told on this forum that BMW calls for 25 n-m, or 18 ft-lbs. I think I saw a video online with the same. It's also the same as the oil filter housing top on my E36 M3. BMW uses quite a small diameter drain plug compared with other cars I have, so 18 ftlbs sounds about right.

This is from a BMW service manual. May or may not be for a B58, but 25Nm is the most common value I saw anyway.
In most cases matches the torque for the plastic oil filter housing. They make it easy to remember

18 ft lbs seems right.
