Only accurate reading is on the dipstick after the car has been sitting for three days on level ground. It’s a flat engine. Takes a few days for ALL of the oil to drain down.

That is always how I have done it for 5 years now.....certainly 9 quarts has always left it full in the past.

I have heard a rumor this is only true on the American version of the Special Edition. No other Boxster has the ability to detect the additional few drops after the first 24 hours. All other owners should follow their owners manual for detailed instruction on checking oil.

It's true, but the feature only works if you use the more expensive self-leveling oil.

HAHA! Yeah, my 02 is pretty dead on within a few minutes on the stick. Interesting though you put in 9+ quarts. Even with my oil pump drained and filter (updated the plunger) Mine was "full" at about 8.75 give or take.

Har....

...thats funny right there.

Do what you will, I'm telling you these cars are hurt more by OVER filling than by under filling.

Folks go on a trip and freak out when the digital gauge shows empty at a fuel stop and they throw another quart in there. They are over filling and blowing their AOS.

Happens all the time and is one reason so many AOS blow.

And, why yes, my American market SE is filled with all sorts of unique features.

Witness Mark

I will always trust the witness mark on the dipstick more than the generated bar graph, I have always used 9 quarts on oil changes with a new filter of course every time. I also let the car drain for 20 minutes before I put the magnetic plug back in.
