Fuel economy is generally reported between 16 and 22 mpg. The original window sticker said 19. I have heard people say they have gotten as much as 30 mpg. The most interesting story was a guy who installed a Floyd? carberator from the 50"s and got 30 mpg. He was technical enought that a really believe his numbers. He was at the Cincinatti show. BTW, this Floyd? guy is the one that was misteriously kidnapped and killed in the Everglades after he anounced he was going to mass produce the carberator. Check the news paper from around 1954, its a true story. Dr. Bob
