Cool thing I found out about Sunoco and Shell Gas

So how about turbo vehicles than that come from the factory? I’m sure you can use 85 gas in it?

Also, why do all tuners tune cars for either 91 or 94?

Must be a logical reason.

Lots of turbo factory vehicles require 91…thats a 95 RON or higher.

Pretty much any turbo car calls for a 90 minimum for optimal runing condition, anything lower and the the knock senor pulls timing.
