i just bought an S6 with 73k on it just looking for advice on some engine treatments. i was going to use the liqui moly engine flush and gas system cleaner. what else would you all recommend i do?

just like you said, do a good engine flush, put some simple treatment in for the fuel, and do a good oil change after you flush the engine with some of that liquid molly additive (Ceratec). Keep it simple and you’re golden! 👍🏻👍🏻👍🏻

Check if the BSG has been replaced, new BSG part #is 4N1.

If not, then there is an ongoing recall/campion to replace these old version BSG to the new 4N1 part. Currently only covering 2019 and 2020 MY. Your 21 and my 22 might need to wait some.
