I just use LiquiMoly 0W-20 with the VW spec
The 508 spec gets you better mpg and less dirty emissions. Gotta look at the bottle carefully. Mobil ESPX2 0w20 has that spec.
262k miles here on an M54B30 with 10k changes, Mobil 1, it's running great.
It should be fine. I use Mobil 1 and it's worked great.
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.
I use Mobil one in Canada when it goes on sale synthetic 0W20 10 k intervals 13 yr old corolla 1.8 and 15 yr old tundra 5.7 350 k and 320 km ; no oil consumption work great
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.
Mobil 1 for me is like water in this car. I ran it for the longest time till I was tuned but switched over
