Thought I’d 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.

This is very useful indeed to sample data vs analyses of conventional oil. Looking at these data already switch to quantum (as long as i can get it in Europe) makes sense and should allow to extend the change intervals a bit.
