I had oil burning issues even with 10W-40 in my high mileage 325.\nMy mechanic put in LiquiMoly 10W-60, which seems to be much better.
Pros: seems to be much better

5w-30. I use LiquiMoly Molygen and my experience is good.
Pros: good experience
I use it on my 2016 S5 and it’s wonderful. It’s basically the same as Leichtlauf just with the friction modifier and UV capabilities if you need to spot an oil leak (only in the first 300 or so miles because then the oil gets too dirty to work with the UV). I’ve heard the friction modifier works well in older performance cars due to the increased wear of their engines. Yes it’s technically not approved but you won’t go wrong with it.
Pros: wonderful, friction modifier, UV capabilities
Cons: UV works only short term
Vehicle:
Audi S5
I use the Leichtlauf High Tech. Really helped my higher mileage SQ5 with chain rattle.

I personally use Liqui Moly. I've tried Castrol, Mobil 1, Amsoil, etc. and my BMW (E85 Z4M) runs noticeably more smooth with the LiquiMoly.
Pros: runs noticeably more smooth

I wouldn’t put anything other than Liqui Moly in my Benz. I used to take my car to Wheel Works, but after long drives, it would smell like burnt oil. Switched to LM and started charging the oil myself. I’ve never smelled anything after that for years. It makes a difference for sure.
Pros: no burnt oil smell, significant difference
