I see this is an old thread but I'll just throw in my 2 cents to say that I've done 4 oil changes on my 991.2 C2S and average around 9.3 quarts per fill. I've had the car almost since new. I've used Mobil 1 FS 5W50 on the last couple of changes. I back my car onto 3" race ramps giving it a slight incline toward the front of the vehicle which I do believe aids in getting the most oil out of the pan. I'm also not typically in a rush and allow as much as a few hours time to drain which I don't believe is necessary but when I return, there's always oil still dripping out of the pan albeit slowly. This could easily account for a good few hundred MLs of fluid vs just letting it drain for 30 minutes or so. Also worth noting that quarts are slightly more than liters (9.3 qts = 8.8 liters).

I do similarly to Tier1Terrier on my 2017 C2S, except that I raise my car using a floor jack and slide a 6" HD ramp under the rear wheel on each side before proceeding with draining the engine oil. I leave the front wheels on the garage floor. The floor is level. I use an old cardboard box as a support for the oil catch pan which is also a container for storage and transport of the old oil. I loosen the oil filler cap and the oil filter housing and let the oil drain at least a half hour while doing other maintenance items. I measure the amount of oil that is drained out using empty 5-quart jugs that were originally filled with motor oil. I have yet to observe any leakage onto the surrounding engine or dripping from loosening the oil filter housing to facilitate drainage into the sump, but still stuff some paper towels around it just in case... .
I, too, have consistently drained more than 9 quarts, and almost exactly what Tier1Terrier has observed.

In the past I drained at 5k intervals. As I am retired and no longer commute I change the oil yearly usually 3k or so per year.

If the oil is properly drained, 8.9 to 9.1 on the 4S. The 2015 has a few more measurement lines on the gauge than later cars and I like it one from the top. Most dealers will fill to just below that line. At almost 90K miles, and “driven”, it burns NO oil.
