Well there's a reason why Barnum thought there was one born every minute... These companies have preyed on the un/missinformed public and will continue to do so. Being in an independent shop environment for quite some time, I had my share of customers bring in MPG savers on their high mileage, unmaintained vehicles... I installed none. Some went off in a huff, but were back shortly to get routine work done. Needless to say they were much happier and even more grateful.
