NOT losing oil
When I bought my 05 997s in July 2006, the first thing I did was get an oil change. I've now driven about 6k miles and I have not yet seen the oil level drop (still at the top level). I know you're supposed to lose some oil normally, so... am I missing something here? Performance is otherwise excellent and gas mileage seems reasonable (19-20mpg). Oil pressure and temperature seems normal, too.
Anyone have any ideas?
Thanks!
Jimmy

What sort of driving do you do? Short drives? Long drives? It's quite possible that a bunch of short drives are adding condensation moisture to the oil in an amount that offsets the oil that is used. Engines should use oil,--with every stroke they burn off that ultra thin layer from the side of the cylinder.
I used about 1 quart/litre per 1000 miles while in Europe,--during the initial breaking in. After I changed my oil at about 6500 miles that rate seemed to go down a bit, but not a lot.

Engines SHOULD NOT use a measurable amount of oil. although Porsche has tried to convince people that this is a normal phenomena of an internal combustion engine. A loss of oil, other than a leak, will always result in less performance potential of the engine burning the oil.
Over the years, many Porsche owners have accepted it as normal and unstoppable, mainly to ease their own minds. Great marketing by Porsche.

If the former, this was discussed in depth not too long ago and a simple search should turn up the thread.

Overfilling the oil can lead to foaming of the oil which can reduce lubrication and increase heat. If you had to choose, it is better to run down a quart than over a quart.

No, I'm serious..I maybe smart w/ puters and other stuffs. When it's come to car, I'm Gomer Pyle in the big city. I just listen to my Service Advisor and add a quart every two months or so. After reading this thread, I just wonder am I overfilling it. Not to the point of spilling it out of the engine, but flooding it?? No harm?
Searching? trying to cut down ion this Forum. It's too addictive, a simple search on a topic can cost me hours of reading other interesting subject. With raining season over in So Cal, Gotta go out and start making money. Anycase, thx in advance for replying this naive question.
