When my Mk6 was at 100k+ and burning up oil every 2500-3k miles, I got a tip from an old audi master tech to use BG MOA additive with every oil change. Cleared up the consumption and let me get up to healthy 5k changes with plenty of oil left. Drove it to 185k still running like a top.
Pros: cleared up consumption
Vehicle:
Audi
Mileage: 160934 km
