Amount of oil in TTS
I change my own oil and have since I bought the car new. Every time I change it I find I need 8.5 quarts to
fill it although the manual says 7.5 quarts. Anyone see this on every oil/filter change? Car is a 15 TTS and
has 23k miles, it burns no oil.

Same deal here...I think it took me ~8.7 quarts to get one block below max (ie two blocks below overfull). That 7.5L/7.9 Quarts at max is questionable...it gets worse if you trust that with the "difference between the minimum and maximum marks on the segment display is approx. 1.7L/1.8 Quarts" statement. Don't drive your car with 6.1 Quarts kids...
BTW...from the workshop manual "Filling capacities - 991 Turbo and 991 Turbo S: Filling capacity after disassembling engine: 10.4L" (11.0 Quarts)

I’m pretty sure it’s a function of how long you let the sump drain. Last time, I got distracted by something and the sump got to drip for 4-ish hours. Took 9 quarts.

I just looked at my notes: 9.25 quarts to get to 4/5ths on the cluster gauge. That extra - accidental - 3.25 hours of dripping makes a difference...

My highly trusted mechanic from Orbit Racing in Riviera Beach, FL has a great technique that he uses on modern Porsches. He measures the amount of used oil that came out (including the filter oil) and puts that much in as a baseline, then adds oil as needed to top it off.
As with Dave C's technique, he likes to let them drain overnight and re-fill them in the morning to get a more complete change.
