Today we have infomercials; back in the old west, they had the snake oil peddler. These characters were largely known for selling patent medicine—the primary ingredient of which was usually alcohol—though a little web investigation (gotta love wikipedia.com) revealed that many of these charlatans actually sold snake oil, as in concoctions made with real snakes and who knows what else. Either way, there was always an enthusiastic accomplice on hand to testify that "it'll cure what's ailin' you," convincing the audience to part with some hard earned bucks in search of a miracle cure. Sound familiar? So I ask the question: What snake oil solutions have you tried in the quest for better mpg? Magnets? Vortex generators? Ionizers? Vapor injectors? Atomizers? How about water injection? Don’t be shy—tell us if you’ve tried any of this stuff. We’d love to know if any of it actually worked.
