No whoever is telling you this is wrong. For oil to get in your boost hoses means you have a turbo seal leaking.

I have not fooled with my 996tt turbos as of yet but have quite a bit on A4/s4 and they have all had some oil in the inner cooler hoses for what that's worth lol.

Using your math, 3% of 9L is 270ML or about 1/4 of a Liter. Not much but if you had your car filled to the very top (max limit) how would you feel about putting in an extra 1/4?

Guess there is some logic to the statement...

Any oil in the intercooler hoses you need to have your indy check on your turbos. Trust me when i tell you don't let them get any worse if it is the seals.

if you are simply overfill your oillevel you can get get oil in your boost hoses too, because the overfill line goes into the intake boost hose

I just asked if we had and oil fill drain at Porsche they said no. I have over filled mine and I never had any oil in my pipe so I recommend to get your turbos checked.
