well, changed the oil today on the 04 boxsyer S today at 40K. No debris, etc in the oil or filter......always a cause for celebration. With 3 porsches and usually at least 10K a year driven in each one it seems like I am changing oil in something about every month or so.... small price to pay for this much enjoyment. Since buying the lift for the garage I find that I can do an oil change in a very few minutes if you discount the 45 minutes I let it drain to be sure all the old is out. I am sure the dealer does not allow that much drain time. Oh well I just saved myself about $125, Now I can afford that beer I am getting ready to have.
If you're not living on the edge you're taking up too much space.
