    I have a co-worker that uses nothing but Aviation fuel in his 2005 fatboy,he also uses it in his 1974 chevy nova SS with a 427. His exhaust pipes on his bike are pure white inside .....he doesn't put many miles on either one but I don't think I would run straight AV fuel in my bike or car....would you? I might mix some in now and again with gas though. You can sure smell it.....lol. He says it won't hurt a thing....I don't know about that.

    It's similar to diesel fuel,I know that.I pumped plenty of JP-5 as a squid.

    We had a Cenex that had a pump on the back of the building that was 96 octane rated.
    That was a great performance improvement on my old Yamaha.

    High octane gas in a stock engine is a waste. I'm not gonna try to explain it. Do a Octane vs Horsepower myth, and read any of the results.

    I used to run 103 AV fuel in my race car, mixed with a top end oil. Wouldn't think of running it in a stock engine waste of money.
