Ravenol is very expensive, so if my UOA and VOA looks good on Amsoil on my other car, I may switch to it on the S55.
Castro 0w40 Euro (made in germany) is majority PAO based, as is Castrol 0w30 Euro (Made in belgium). These two out of the entire lineup are the better ones made out of PAO. Motul has a lot PAO formulated oils as well, like the 8100 series. 300V is ester based. What's the issue with these PAO based formulations that you don't want to use them?
