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.

For a TTS it is 7.5 Liters (7.9 Quarts.) It is similar for me on a 14 TTS. It uses a bit more, just over 8 Quarts (8.2/8.3) for the level to be green, and mine hasn't showns signs of burning oil either. Hopefully my sensor isn't bad and I'm over filling it haha.

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.

Is there a benefit to letting it drain that much? I wouldn't mind leaving it draining overnight ha! https://rennlist.com/forums/images/icons/icon10.gif

Yeah 7.5 Liters.I let it drain 30-45 minutes, didn't think that made a difference. thx Guys.

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...

I use M1 5w-50 was using M1 0w-40, but switched on LexVan oil analysis numbers.

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.

So how much oil is in the total system, I think I read there was a total of 14 qts flowing around, but only half of it comes out at every oil change basically?
