The only thing I can see that would effect my octane requirements is my timing, which is set at 14 degrees BTDC. Other than that, just a few bolt ons, stock heads and shortblock, etc.

I've been running 92 octane in my car for awhile, but it's getting expensive...is it even necessary for me to run 92? Would 87 work just fine? I've never even tried 87, so I have no idea! :)

HAH! My Mustang gets better mileage than ANY vehicle I've ever owned, it's my 7th vehicle.
