I just use LiquiMoly 0W-20 with the VW spec
Liqui moly solved lifter noise on my old Kadett.
Liqui Moly Molygen 5w-40
using a heavier oil weight has been an old trick to help with oil consumption in Subarus for a long time now. I used to use Rotella 5w40 (before the reformulation) in my old 04 Baja Turbo and that particular oil was the best to keep the oil burning down.
I recently changed the engine and transmission oil in my car and opted for Liqui Moly, as from what I researched it withstands higher temperatures compared to the OEM.
I’ve personally been running Liqui Moly LL-04 5W-30 as this grade seems a lot better to be using in a high performance engine to induce longevity. Plus the gen 2 B58s don’t have the same oil pump issues as the gen 1.
My regular since i think 2014 or so has been helix ultra 5w40 running in all my vehicles currently.
My own experience: liquimoly Mos2 leichtlauf. The one with grey oil.
I did an oil change with liquimolly 5w-40 and added liquimolly lifter additive, and drove it for a week hoping it would go away.
Start by getting rid of that junk liqui moly and replace it with ROWE RS 5w40 (i can link many kits if need be)
