How nice would high octane gas be?

Those racers would surely have to use appropriate parts..they are not 10% ethanol / 90 % gas.
Don't get me wrong...I have not used it, but i don't know anybody that has problems who use it regularly.I do know enough not to trust the internet or guys that repeat what they read or heard.Common sense goes a long way here.
the best info will come from guys that use it
LOL!! Well since by law we are all using 10% minimum content, maybe You'll take the word of a Professional Technician who has worked on cars since 95% of those were all
still carbureted. In the 80's, even applying to fuel inj. cars, Mopar issued a TSB not to use I believe it was Boron at the time, purchased by BP, who later purchased Amoco, for
the express reason of alcohol content. And as of this very moment, the brand I work for specs no greater than the old 10% minimum, which I just tested for 2wks. ago( it
passed...barely). Now the mandated level was supposed to be raised to 15%, but I haven't tested any at that level yet that wasn't otherwise contaminated, You wouldn't
believe some of the crap that goes on fuel-wise sometimes. A Friend & customer w/a 440-6 'Cuda found out one of the local station owners was letting a buddy dump his
waste paint thinner & other s**t in his tanks to get rid of it!! "I'm never f***in' buyin' gas there again!!" Yeah, no kidding. We've taken 3 yr. old cars rarely driven & had
to drain the tanks because of the moisture accumulation just sitting, would barely run or not at all. Ehrenburg did an article on sludge & modern gas, alcohol loves water
more than it loves gasoline, once they combine it just don't burn Dude.
Common sense says, if it's not a newer car w/compatible components, and adaptive fuel systems made for determining alcohol content, it ain't no good...THAT'S real.
