V10 Higher Octane?
I have a 2002 F350 V10 with 235000 miles on it, and I have always tried to run the higher octane gas. Just wondering if that was a waste of money? Thanks Rich

I used to run 87, but when they started messing around with the Ethanol in the gas in 2010 (yes they had it before then, but they messed it up more in 2010), I lost power and mileage. I was down to 5mpg and the truck had a hard time doing 55mph into any headwind! In WI, I filled with 93 non ethanol and it was a night/day difference! power and mileage returned. back in IL I ran 93 all the time and it was fine. I then got a tuner from 5 star that lets me run 89oct. and gets me my power and mileage.
