Oil change at trusted mechanic vs. Dealership

Wanted to update everyone. The quote over the phone was a little low. I got it done today and the final tally came to $142. He said he forgot the Porsche engines take 9 quarts of oil. So there ya go. Still pricey, but a heck of a lot better than $340 the local Porsche dealer quoted me. Thanks all!

DON'T let him willy-nilly put 9 qts in. Have him start checking level after 7. It will probably only take 7.5 to fill. If he just dumps 9 in you'll be overfull, which is just as bad as underfilled. When too full, the oil needs to find a way out, so it will blow out the membrane in your AOS and fill your intake manifold on it's way into the combustion chamber to foul your plugs. On the way out, it will coat your cats and put soot on your exhaust tips.

To paraphrase Pedro Cerrano from 'Major League', it is very bad to overfill your Boxster, very bad!

Is that really the rule rather than the exception? Mine's always taken pretty close to 9 qts. Is there a lot of variability from one car to the next?

I googled 'Porsche M96 oil capacity'. Pelican says you'll need 7-10 qts. That nailed it down. The next entry said 8.5L. When I convert that to qts, it equals 8.9 qts. So that's probably where everyone comes up with 9Q per oil change. However, that assumes all the oil comes out, which it doesn't.

It's always easier to add oil than remove it.
