Just got my 01 996 tt a 30000 mile service. It is burning a quart of oil every 600 miles. Porsche claims it is normal because I drive the car hard. I don't....is this normal???? Please advise.

It sounds way too high to me. My '02 with 13k burns NO oil. It used alot for the 1st 1000 miles, once the rings seated it has used very little. I'd push for a leakdown check.

Peter.. Have someone check your turbocharger inlet pipes for oil.. Hot shutdowns will shorten the life of the turbo's... Do you see a puff of smoke on startup?

at 30k, it does sound high. i have 20k miles, and go through about a quart every 4-5 thousand miles. it almost sounds as if your rings never seated, but, if you drive it hard, that is probably less likely.

Rarely do I see smoke on start up....one cold start every few months..the car is a daily driver.

This may seem like an idiotic question? What does it mean when the rings don't seat and what does it mean for engine life/addtional problems?

Kevin

The term rings haven't seated,is referring to the sealing rings that are on the pistons in your engine. They are designed to seal the combustion gases. We want the gasses to exit out of the exhaust valve, not to be blown past the piston... The other function is to oil the cylinder walls and piston skirts.. And oil control, with the oil scraper rings. When an engine has not seated the rings, oil control is lost and burnt in thee combustion process.. Blowby is another result or sign of failed rings... What most people don't realize, all engines need to have a load put on them to seat the rings, no load or "babying" the engine will promote carbon build up on the rings surfaces, thus the ability to control the oil is lost. Once the rings carbon up and glaze the cylinder walls. You will need a top end overhaul to fix this problem..

My 04 TT cabriolet has been burning about that same amount of oil, and more often then not I have a large amount of smoke blow out of the backend during a cold start? What should I ask the dealer to do. I am taking it in for what I think to be some failed BOVs so I might as well have them take a look.


I forgot to mention I have just ove 6k miles on the car.

I have a 2002 996 TT with 21k miles on it. I always cool down for at least one minute and don't drive very hard. I occasionally a puff of smoke on start up (maybe once a month) and notice little drop in oil between changes, maybe 1 quart every 3000 miles. Should I be concerned? I bought the car used and don't know how it was treated for the first 12k.

Chandler;

I wouldn't worry about it.. If it gets worse then you can investigate some more.. It's the nature of the beast, since the turbo's sit below the oil line.. A fog show at start up would prompt checking the inlet tubes for oil..

Thank you.

PORSCHE'S LINE ON OIL CONSUMPTION IS 1QT/PER 6-700 MILES.ANYMORE IS CONSIDERED EXCESSIVE.IF I AM MISQUOTING,I'M SORRY,BUT THAT IS THE SPEC I REMEMBER.

The first 1000 miles mean really A LOT: if you drive hard, you stop the engine when hot (don't let the turbos cool down a little) and so on, the consumption of oil will may be higher than normal, if like said already the rings don't seat.. I am saying this just because I saw it happen to two friends of mine. You should have seen the clouds of white smoke when they were starting the engine: unbelievable. And they were daily drivers; but they wasted the cars since day one: no mercy! But after all who cares? You keep adding oil and after all it is like if you are running an engine with brand new oil all the time! (Sorry, it is sarcastic....) AT $7.00 per quart ....

I have an '04 TT cab -- at 3k miles still burning 1 qt every 600 miles. Dealer says not to worry -- we'll see if it decreases -- I hope so

Iloveheat

MMH: tell me how you drove the first 1000 miles. Did you go over 4000 rpm? Did you drive easy or like an animal (like all of us....)?

A common misconception regarding engine breakin is that you need to really baby it for a few thousand miles. In reality, an engine needs some load put on it in order to seat the rings properly, and to help the various rotating parts to mate their surfaces. Piston Aircraft engines are broken in under high power - 75% or better - in order to seat the rings quickly. In my experience, some people run their Porsche engines so gingerly that the cylinders glaze over ( like being polished) , and thus the rings never do seat well. I'm not saying that it's wise to go out and redline it when it's new, but it is smart to get into the gas and put some load on the engine .
