Same as title.
How tight do you tighten the oil filter on a C300.
I think I must have overtightened mine causing the gasket to shift and leak.

vic,
I didn't have any problems on my first oil change last year. I think I kept turning it with a rachet wrench till you could tell that it had gone as far as it was going to go.
I must not have tightened it enough this time. I'm off to get a torque wrench.
Thanks

whoaa.... I haven't change oil on my MB yet but I've always hand tighten the oil filter on every car I've ever changed oil... You can easily overtighten it and cracked the o-ring if you use a wrench...

I now have a corner of my garage painted with mobile1 by hand tightening plus 1/3 turn.
You might want to hold off on the hand tightening till I get this resolved.

......oops,
In another thread I asked the same question and someone suggested that I had the o ring in the wrong grove. I was certain their car was different until I looked at the instructions that came with the filter and sure enough, it goes in the second grove. I put it where intuitively it seems that it would go but that's wrong.
As for hand tightening, I don't know. I put the torque wrench on it to 25Nm and ran the engine for a while to see if it would leak. Didn't leak.
I'd like to thank vic and jog who joined in this discussion.

Get a quality torque wrench and follow the specs. Vic suggested 25 Nm and that seems reasonable unless the shop manual suggests otherwise.

I did buy a torque wrench to use on filter tightening this afternoon.
But that wasn't the problem. I had put the big o ring on the top grove instead of the next one down like you're suppose to.

Good - you can never have too many tools, especially power tools!
Ouch!

I use Automotive Wolf to track things. It would not let me forget.

My filter cap had a dot of paint on it marking the top with the bottom, I hand tightened the filter cap til the paint mark once again met up, it was snug enough that I had zero doubt it would be a problem with leaking, so far so good.

Correct about the "dot", if you use that as a guide you can't go wrong. In any case, you get a sense right away that you've tightened enough, there is a natural stop in it.
There is a printed guide with the filter that shows you where to place the top O ring, its not at the top most positions, its one "level" down from there.
Did you drive very far, did you get much of an oil leak? That could really be a mess or could even cause an oil fire.
