Shell does not put ethanol into their V-power gas, it's 91 octane. That is all I ever use.

Ethanol is fine for the Z's engine. Straight E is less energy dense than gasoline so it requires a tune, aka injectors to be scaled roughly 30% more.
The thing to watch out for E is having rubber fuel line because it will eat the lines and then it will end up in the fuel injectors. All the fuel lines should be PTFE.
I ripped all the fuel lines out of my car and can't recall exactly where, if any, rubber lines are in OEM form. Charles/Phunk with CJM is pretty much the authority on OE fuel lines and what to do.
