Thought Id post this, you can see the mileage, I usually try to keep it below a 7k oil change but got side tracked, work, too many vehicles. I use this specialty oil (Quantum Blue 7.5w-40 custom mix) in my Stg2+ S5, Stg2 RS5, and Stg2 RS6. I use Redline 5w-40 in pretty much the rest of my vehicles.
