People have been suckers for "fuel saving" gadgets for about as long as cars have existed. The list is endless, but a couple that stick out in my mind are the mythical 100 MPG carburetor and the more recent "HHO" hydrogen producing gadgets that scammers promote.
I like the one where you drop a tablet into your gas tank then fill it with water and drive away.
