Ps, u could get 104 octane in ur gas in 1965, now u pay 10 bucks or so for a pint, go to a special outlet, u can get high octane gas maybe in ur town for 5 bucks a gallon........
LOL, I remember as a "kid" going to the local county airport to top off the tank with aviation gas on drag race days.
My guess is that this is now illegal since aviation fuel is still leaded.
