The best I could tell, my 997S was burning a little over a quart per 1000 miles, which if I could have been sure, would have been no big deal- however- with no dipstick, I could not monitor closely enough to determine oil consumption was not increasing due to bigger issues.
The car was SOLD the next week. FU computer dipstick.
As an aside- my wife went to buy a new VOLVO engine with no dipstick. Not only was there no dipstick, the computer only registered "full" or "empty"
There was no inbetween.
Deal off.
Also- there were people retrofitting dipsticks into the volvo block even back in 2015.
God bless them!- basically- check to see if your dipstickless car had a dipstick design a dipstick for it. Worth a shot.
