I inherited a 68 Camaro SS 396 from my late father. It has 23K miles and for the most part original. I think he had some stuff done to the engine to make it run better. I know he said it has high compression from what he did. (sorry, I'm not much of a gear-monkey). Because of this, he would say that it needed Turbo Blue 110 Octane gasoline. At that time, there were a few pumps that had that stuff. Illinois has since outlawed it (I think). Anyway, my question is, what should I fill the tank up with? I primarily drive it to and from shows, and a couple times throughout the summer around town. Will 92 octane with a can of that octane boost do the trick? What about ethanol? Most high octane blends are from ethanol. Any suggestions appreciated.
