I had a '67 dodge dart with the old 273 V8/2bbl carb/mechanical points that
*consistently * ran better and got better mileage from cheap lo-octane
gasoline from shady indy stations, the kind that'd probably been cut with 5%
kerosene by the russian mafia. Even after an engine rebuild, it got 1-3mpg
MORE on that cheap crap gas. Never did find anyone who could tell me why.
