What Fuel do you guys run in your stock S5 T2's?
My friend once told me that his turbo rex ran worst when he used 94 octane?
What is the best fuel recommended to run in a JDM 1991 turbo rx7?

I always run 93 in my TII, but im super paranoid about pinging. Technically, the higher the octane you use, the crappier it will run, but lower octanes have higher chance for pre-ignition. I dont mind suffering a litte performance for engine reliability though

Manual says to run 87. If you want to be safe (detonation) and/or have mods run 91 or better is my understanding. I run Sunoco premium. Also, anything other than regular in a stockish NA is a waste of money.
