Yep, I like the Motul oil flush procedure.

Going to do it on the RS6 as well. Not every change but maybe every other.

Keeping with Aces on RS6s but with the shortened intervals on the S8 I’m going with Motul 5/40 8100 xcess.

APR is the best tune on the 4.0tt

Debating going with the APR tune now, which seems the most reliable for the C7. I'm similarly not following the 10k oil change schedule from Audi, but the Motul oil flush is a good idea.
The Avant project looks great, congrats on that!
