997.2 Oil Question

Do this as a test. Get the oil hot and drive home and park in the garage and check the oil level. Then turn the car off for 3-5 minutes and start it back up and re-check the oil. You will see that the 2nd oil level check will be higher than the 1st. This is why it is very easy to over fill the oil.

I've got about 7,500 miles on mine and the black soot is much less now than when new. I'm not sure if it is the mileage or the fact that it is summer time and when starting the mixture is much leaner than it was when mileage was lower and it was cooler last winter. Consumption has gone from a quart very 500 miles to a quart every 2,500 miles now.

I have been dealing with tail-pipe soot for several years. It's at the point that frankly I'm a little surprised (knowing Porsche) that they haven't painted them black to hide the soot--like they were done years ago.

My dealer is baffled and PCNA will not say anything.

The 2009 oil level indicator IS NOT accurate and you check the oil with the engine hot and running...BUT...when you shut the car off and let it sit for 3-5 minutes and re-start it...the engine is obviously still hot and the oil level will show more bars...especially if the 1st check show mid level or lower level on the indicator.
On a 2009 DO NOT ADD OIL if the indicator is at half lighted bars! Only add when the skinny lowest line is blinking. BE CAREFUL NOT TO OVER FILL!

You probably use very little. What amount you do use is probably being offset by moisture. Do you drive mostly long trips, or a bunch of short ones?

Mike the reason you have black soot is becuase around town you are probably running a bit rich and the car doesnt get to stretch its legs. Then you go to the track the car gets to run like its supposed to and your
color turns to the perfect white grey.
color turns to the perfect white grey.

Both long and short. Mostly short one avg 10miles per segment. Had a long one @ 2500miles around Cali, Nev and AZ, still low to no consumption. Was expecting at least a quart every two to three months, nothing significant at all. It's time for my 40k service anyway, will find out if there are any oil left.

checked oil level twice today and both times full bars. I've also noticed the car 'loosening up' the past few days. I guess the engine is breaking in nicely. I've driving it auto, auto-sport and manual-sport. I did not try the 'plus' button yet...

I'd like to run it harder on the street but If I run it up through the gears I am doing well over 100mph in no time.
I just need to go to the track more often. I am on a self imposed track ban until this fall...self control is notone of my best traits but I'm trying.
