Default Interesting comments, thanks.......

This is after only three days of driving, maybe 120 mi. I am curious to see if the car will pass the PA emission test with this amount of particulate expelled from the tailpipes. My garage floor shows no deposits of soot so I don't think the cold start/condensation thing is the culprit. It does seem odd that Porsche has, at least through my dealer, ignored this quite visible pollutant problem, while introducing the new 918 Spyder. Maybe the pollutants coming out of my tailpipe are not classified as such? Maybe this is environmentally "clean" soot like Mike's Toyota Hybrid. (thanks for the pic). If so I will feel better and keep the Zaino well maintained.

I have NO INTENTION of pursuing a lemon law action as the car is so much fun to drive. This is my 6th Porsche and they keep getting better and better. I do feel badly for Porsche's reputation though as some customers will shy away from the marque if it is a luck of the draw whether you get an oil burner or not.(as in the case of the poster who was so unhappy with his new 911 he went back to Corvette). Life is too short for me not to drive a Porsche and over the years I have been treated very well by my dealers, but all my previous Pcars were basically trouble free. I had 66k on the 930, as well as the 986S. Thanks all for your inputs, I have to go add another quart of oil, the low bar is flashing, and then go for a wonderful, top down, holiday drive.

This Easter is an anniversary of sorts for me. I was showing my best friend from the city how wonderfully stable my new 1982 911 SC was at speed. I was on route 78 in PA on Easter Sunday with hardly anyone else on the road. I was going VERY QUICKLY and passed a Mustang Cobra at speed. I slowed to around 80 and the Mustang began to follow me. I sped up, he sped up, and so it goes. I kept it down and he disappeared slowly into the distance. Unfortunately for me he was a PA state trooper in an unmarked car! Long story short, I wasn't arrested, (85 in a 55, as that's as high as his speedo would go) but the ensuing ticket did push me over the edge and I lost my driving privileges in PA for 6 months. I will be extra careful today hahaha

[QUOTE=Todd in PA;74526In all fairness though, if Porsche was to offer a buyback to me right now, I wouldn't take it! I love this car, there is no substitute.[/QUOTE]

If Porsche offered me a buyback right now I'd take it.......I'd turn around and find a Porsche with a thousand miles on it that doesn't burn a quart of oil every 600 miles and buy it....
It may or may not resolve itself but I'd prefer a car that didn't blow black crap all over the place...

I would get the emission test to have it documented, maybe force the issue.

Are these cars that drink more oil associated with a certain (early) build date on the DFI engine?

I admire your ability to maintain a positive attitude even in the face of frustrations regarding the soot and oil consumption matters. I do hope that you are able to resolve these issues to your satisfaction. Please keep us posted.

Beautiful car, by the way.

Is it fair to mention that hopefully this only happens to a few "problem" cars and is not across the board. If I knew ahead of time, pre-purchase, that my new 911, list price at well over 100,000 dollars would burn oil at this rate, and pollute the environment with soot, unlike my previous 5 Porsche cars, I would have delayed my purchase until this "perhaps a problem" was rectified. In all fairness though, if Porsche was to offer a buyback to me right now, I wouldn't take it! I love this car, there is no substitute.
I have the SAME issue. My wheels are clean as anything, but the rear bumper is full of soot too...

Is anyone ready to start a list for all of us to get on to address this yet?

So why can't we all band together and fight this with a letter?

I have the excessive oil consumption and the soot. I would like a clean bumper like the rest of you. Why shouldn't we all band together and address the situation.

Porsche NA has refused to take back my car or even ADDRESS a fix to the engine.

All this oil running through the combustion process can't be good for the cats.

Has anyone tried a different oil viscosity (such as 5W-50 or 5W-40) to see if it makes difference? Mobil has Delvac1 5W-40 which claims reduced sooting properties in HD truck use, and it's rated for gas engines also.

This is the only Porsche I have had that puts out unbelievable amounts of soot and burns oil at the "Porsche approved" rate of one quart in less than 700 miles. I washed my car last weekend and have driven it these last 3 days in the nice weather. I tracked my previous cars and was a driving instructor for Riesentoter region. I drive enthusiastically and thoroughly enjoy the full rev band! I have a 6 speed manual transmission and don't drive for "mileage". For those who do not have any oil consumption or soot problems with your new 997.2s, please don't belittle or imagine that this is not a very disturbing problem for those who do. I can't understand how these tail pipe emissions are acceptable in this day and age! I am still in love with the car and am documenting these problems with my dealer. BTW my '09 BMW 535XiT, twin turbo, DFI engine does not have excessive oil consumption or soot.
I had the exact same thing on my SY 996 AFTER I installed a GHL exhaust. It never bothered me that much...

i just took exhaust off car today twice and soot is just everywhere.. cleaned it off, going to see how long before its back again... the soot at each joint in the exhaust was insane.. when i pulled off the pipe it would just fall out.

Todd - had the same problem on my 2006 997S. Lots of soot. 1 qt per 700 miles, etc.

PCNA unwilling to budge, district rep from Porsche unwilling to budge, dealer unwilling to budge as PCNA would not even approve a leakdown or compression test on my motor.

Now, with 17k miles, oil usage is way down, perhaps 1qt per 2000 miles.

Granted, I have a different motor than you, though my experience may be valuable - Porsche knows there is a problem with some of these cars and is hiding behind the ridiculous spec in the owners manual.

I too have a 535ixT and while it burns a bit of oil and soots up the exhaust pipes, there is nothing on the bumper.

Another thing too - make sure to keep that bumper clean - the oil residue will definitely stain you paint on the rear bumper, no question.

Long story short, I got a decent trade-in value for my car from the dealer that sold it to me, though I love the car and with current oil usage rates a somewhat acceptable, I'm okay for now.

Hope this helps.

One poster got me worried about the soot stainning the paint.

What people who do not have this problem are missignis the fact we are fanatics about the car. We wash and detail. Only to one drive later have soot flackes all over the bumper. After one drive. Its just not what a fanatic wants to see after he or she has just slaved over the cars appearance.

I know these cars are meant to be driven... but can't they look clean too?

SOOT= PAIN IN THE ****.
