Hi Gareth
Thanks for the reply I have only done done 800 miles so far but I want to change the oil sooner around 1000 miles.I have taken the Audi service plan which includes 2services which the first one is November 2026 or 9000 miles.so I would probably change the oil a couple of times before this service is due.I have priced the oil at Audi and they want £20 a litre which I require 7.1 litres.Audi don’t make oil themselves that’s why I query what oil to use .It will be Castrol or Mobil they use.which you can get a lot cheaper.Thanks.
