I don't want to hijack the thread, but yes it will be my first! Thanks!

It always has been in recent BMWs. Now, the '07s are missing the dipstick........:loco: but I guess BMW deems that to be progress.

I have the same engine on my new CPO 530xit, but haven't done an oil change yet. I plan on going the shade tree mechanic route on my first change. I'll hand tighten to contact, then give it an additional 3/4 to full turn. The spec is only 25 NM or 18.8 ft-lbs. With an o-ring, hand tightening should be sufficient. If not, that's when I'll go and buy a wrench. My old trusty filter strap should be enough to remove it.

Autozone, Pep Boys, Advance Auto carry them - would probably set you back 6 bucks or so if I am not mistaken it measures 76mm in diameter and is a 14 flute oil cap/filter tool, or here its $2.99+ whatever shipping would be
