Attention: TDR Forum Junkies Anybody ever hear of this company? http://www.nationalfuelsaver.com/
My brother-in-law ordered a couple of these units and is going to give them a try on his F-150. (For gas only) They are actually going to send it to him free of charge and if he likes it, he will send them a check. If he isn't happy with it, he'll just send it back. I think something doesn't sound right with it so i thought i would ask if anyone has used this or heard of them.
BTW, they claim 22% increase in gas mileage or your money back.
