There are only a few brands still marketed Fully synthetic Oil in Germany standard. For instance, for 0w20:
Ravenol VSE, ECS, DNF, etc. but not VSH and EHS (group iii)
Addinol Premium 508/509 but not the Addinol Economy
Amsoil Signature but not other Amsoils.
Ravenol PAO are as expensive as Amsoil Signature, and I believe they are better but too pricey.
For 0w40, there are more option that are fully synthetic like some lines from Aral, Meguin, Kroons, Ravenol, Addinol, etc.
I have never seen Liquimoly nor Rapsol advertised PAO or fully synthetic oil in Germany. They are both just average oil, not premium.
Rapsol is known to use group III heavily and cheaper.
The surprisingly good but cheap oil is Mannol with true approval from manufacturers like 7715 7730 7722 and contains >25% PAO.
Most of them probably uses cPAO instead of mPAO.
