Fuel choice

Which fuel do you guys use. I've heard all dif stuff. I have some buddy that have to run premium. But in a regular 454 should you run atleast mid grade ?

regular or 89 if it makes you feel better... They were designed for 87, and will run best on 87.

Run 87 octane non ethanol fuel in stock Merc black engines for the best performance.
