I've been using 5W30 Pento Super Performance III Engine Oil in my n20 for a few cycles and I use it in my b58 as well. I went with it since its an ll-04 oil and since the gasoline quality has improved in the US it makes it a viable option. Has better protection but should be changed more often as a precautionary measure. I'll show my UOA once I get it done.

I also went with that oil because FCP euro sells it so it qualifies for the lifetime replacement. Unfortunately though, they stopped selling it there, so I think I may move to Motul 300v on fcpeuro and change it frequently (3000 mile interval). Mostly switching to 300v because I'm interested in seeing what a group IV or V oil will show in the UOA for the b58 since nobody has shown any data for it on the forums or anywhere else.
