Reading that the 992 street GT3 has oil capacity of about 9 litres and a by the book oil change allows only about HALF that volume to be drained and filled.
Is that the same for the 992 cup version?
OK, found the 992 cup manual. Seems like it is the same!

Reason: Update
Here's the new method on doing the 992 GT3 Cup Oil change...
I catch all the oil into a 12Q clear graduated container and then refill with just about the same amount (assuming I was at a correct oil level before draining). https://a.co/d/7xFIodF

3. Remove the oil drain plug on the oil tank [1].
4. Drain the oil for approx. 5 minutes.
→ Catch the draining oil.
5. Remove the oil drain plug on the oil module [2].
6. Drain the oil for approx. 7 minutes.
→ Catch the draining oil.
7. Thread in and tighten a new oil drain plug on the oil module [2].
8. Switch on main switch [MAIN].
WARNING! Unintentional engine running! !!!*** Ignition [IGNITION] remains switched off!
→ The engine may only rotate at starter speed!
NOTE: Observe warning instructions and information on page 56!
9. Press the ENGINE START button and keep it pressed.
→ The engine rotates for approx. 3 seconds and stops automatically.
Release the button.
10. Wait approx. 10 seconds.
→ Oil supplied by the oil pump during the starting process runs off via the still open oil tank.
Collect the draining oil.
11. Proceed steps 10.–11. in total 6 times.
12. Switch off the main switch [MAIN].
13. Thread in and tighten the new oil drain plug [1] into the oil tank.
14. Remove the oil filter [3].
15. Drain the oil for approx. 1 minutes.
→ Collect the draining oil.
16. Coat the gasket of the new oil filter with fresh engine oil and fit the oil filter [3].
17. Fill in fresh oil with a volume equal to the volume of the drained oil + 0.25 l (oil filter volume).
This process is wild! I can understand it if there is 1 oil change between rebuilds (50 hrs on oil) but this seems like a terrible idea if changing oil every 5 hours. Seems like a good way to damage bearings by cranking the engine with no oil in it.....
If you're changing it super frequently, not quite getting every last bit out seems pretty inconsequential.
How much oil do you usually take out with this procedure ?
Not sure... I don't go through that process. I just change it every 5 hours and drain what I can drain out of the tank and case.
