2017 rs6 performance oil usage info

[Batleyred]

Hi all, I’ve a 2017 rs6 and would like to know how much oil you use. I bought the car in August and have topped up 3 times. I mentioned this to the dealer and they said you can use half a litre every 700 odd miles,. They said it is not a problem to come in for inspection, does this sound about right .

I have put nearly 3000 miles on brining the mileage up to 24 thousand
