Fuel Saving Devices for Cars & Trucks - Do they Work?

Are there fuel saving devices that work? Here's a list of the more popular fuel saving devices that claim to increase the fuel economy or mpg for cars and trucks. But buyers beware; there are many gadgets on the market that will not increase mpg as advertised. Smart consumers should always research and compare fuel saving devices before buying. A good rule of thumb - play it safe and only buy devices from reputable companies who offer a money back guarantee on their products.
