Not correct. Boxsters require 9&1/2 to 10 quarts of oil!!!! Then again, I guess it depends on how often you change your oil? Do you do it every 3,000 miles? That's not what the manual says.
You better ad some more oil. Do you have an owner's manual? Says it in there, once every 15,000 or once a year, whichever comes first. That's why you need 9-10 quarts. Hope you used Mobil 1 Full Snythetic.
