I have an 2002 S4 and have been using mobil 1 synthetic oil. The dealer claims I only need to change the oil every 10,000 miles. Does anyone agree with their recommendation? It makes me nervous. I do mostly highway driving.
10,000 miles is adequate if you’re not street racing (or just have a heavy foot). My allroad has the oil changed by the dealer every 10k miles and I do one oil service in-between. It also depends a lot on how many miles you’ve god on your S4.
