I am planning to change the oil on my S4 this weekend. It has been on longlife (5w30), and last service was 6k ago, but I am planning to go to fixed with 5w40.
The reason I want to do this is 2 fold - firstly I always like to have fresh oil, and I am happy to change oil every 5k miles, so this is much better than a degraded oil potentially doing 20k miles, even if it is so called longlife oil.
Also, i had to top up recently and the Shell Helix 5w30 from Audi was £17 for 1 litre!! So if I cange the oil I will have spare to top up and it will be better priced.
Couple of questions - what is the oil capacity on a B6 S4 4.2 when you are doing oil and filter?
I have priced up GSF and Eurocarparts and both now do Carlube products. The Carlube Triple R 5w40 is around £26 for 5 litres and is 502.00, 503.01 and 505.00 spec so should be the right stuff - is this stuff OK?
Any any other anomolies for the S4 oil change or any tips?
