[Rewted]

The last two DIY oil change documents I've looked at were using a standard 17 mm socket wrench on the drain bolt. Could have sworn when I was reading up on my old e46, it was suggested to use a torque wrench. Should we not be using a torque wrench on our new e9X's?

I just hand tighten them...been doing that for 6 years on my BMWs, no leaks no problems

socket will do the trick just fine... just make sure it's secure and threaded in right and never overtighten

stripping the treads = tapping new treads not fun

e90 drain plugs are hollow...usually the plug breaks off before you strip it...usually. haha
