I just use LiquiMoly 0W-20 with the VW spec
Liqui moly solved lifter noise on my old Kadett.
Liqui Moly Molygen 5w-40
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.
SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.
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.
I use PUP 0w20 in mine. Lots of tests and UOA show that Pennzoil Ultra Platinum is the best non-boutique oil you can buy. But honestly any top shelf oil will work. 5k km intervals are more important than brand with a turbo engine.
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)
