2009 C2S, stick. Bought new and broke in per directions (which was hard). For the first 10 K miles I was burning about 1 quart every 5K miles. Then the consumption lowered to about 1/2 quart per 5K miles.
The total miles are now 45K. I keep the rpm around 3K untill the oil gets up and then try to keep the revs over 4K.
As I only put 2.5 K per year the annual service eliminates the need for adding oil. BTW, when I use the oil gauge I make sure the engins oil temp is warm and the car is on a level surface and the engine has been shut down for
about five minutes, about the time it takes to fill the tank and clean the windows.
Thanks for this poll, I have always wondered why some engines do not burn a drop. My wife has a BMW 2005 325i stick (bought new) with the sport setup and at 130,000 miles it has never burned any noticeable amount of oil and she winds it up when conditions allow.

My 2009 C2 burns about 1 quart in 1200 miles, with 113K miles. I watch temps before I get on it, but I have only owned it 9 months. I have all the maintenance records, but no idea how it was driven. Car has been a pleasure to own, and I have put 16K on it during those 9 months. My previous car was a ‘13 Mustang GT with a ProCharger. It had 156K miles on it when I traded it and would use 1/2 a quart in 5K miles.

2010 C4S with 83K miles.
I guess I am the odd man out here. I follow the Porsche maintenance schedule (these guys have posted a fairly accurate schedule on their site) for my car which is every 10K miles or 1 year. As far as burning volume goes, I am at 1 line below the top according to the oil change animation on my cluster. I drive the car daily and put ~12K on her yearly. I just drove it from NC to St. Augustine and back this week and not a drop is missing according to the indicator.

Folks, dare I say RTFM without making enemies? Page 208 of my manual states "It is normal for your engine to consume oil. The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant. If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the engine oil measurement may not show any drop in the oil level at all, even after 600 miles (1,000 km) or more. It then goes on to indicate "The difference between the minimum and maximum marks on the segment display is approx. 1.3 quarts (1.25 liters). Each segment of the display corresponds to approx. 0.42 quart (0.4 liter)".

Yeah, I'm one of those geeks that reads the manual cover to cover when I buy a new car or bike. It's amazing what I learn doing that.
FWIW I recall reading that the auto oil check process was developed to ensure accurate pressure for the operation of the variocam. I can't find the original source of that so consider that statement anecdotal at the moment.

Regarding the oil check system on our .2 cars, mine is a bit wonky and sometimes, even after it counts down and displays a level, I can hit the wand again and it will countdown from 4 seconds... The results? 98% of the time it is the same but I have had times that it is different, always showing more oil than before... one time it moved up two bars after repeated wand pulls. Why? I dunno... variocam pressure settling? I dunno....I kinda doubt that, there may be alot more going on such as simple re-distribution of oil throughout this engine... there are places that trap oil... I know this because during oil changes, I can get more out by jacking the car up high on the drivers side.

My 2009S burns no oil for the first 2000 miles after a change, then begins burning oil at about 1Qt every 2000 miles after that. I have usually added 2 qts by the time it gets changed again. My OCI is 5k.

I don't think you can assume that following the Porsche maintenance schedule leads to low oil use. These cars will differ right from the factory. This fact disappoints me because I want to believe that modern manufacturing and assembly results in 100% consistancy but apparently it does not. Why the difference from the factory? I dunno but it is true.
