About the so-called FUEL SAVERS sold here.

Products that claim to magnetize or polarize gasoline molecules, realign the molecular structure of the fuel for more efficient combustion, or ionize the spark for better mileage are pure nonsense and are based on false science. So are products that swirl air entering the throttle body or leak air into the intake manifold to improve fuel efficiency. None of these product produces any measurable improvement in fuel economy.

100 mpg carburetors or fuel injection systems? Pure science fiction and urban legend.

ONE GADGET THAT ACTUALLY WORKS

One gas saving gadget that can improve fuel economy is a simple vacuum gauge. The gauge displays intake vacuum, which is an indication of how much load is on the engine. The lower the vacuum reading, the higher the load on the engine and the more fuel it burns.

The gauge saves gas by helping the driver see the effect his right foot has on fuel consumption. Tromp down on the gas pedal and intake vacuum drops and fuel consumption goes up. Take it easy on the gas pedal and accelerate slowly causes less of a drop in intake vacuum and less fuel usage. Duh! Pretending there is a raw egg under the gas pedal can have the same positive effect on fuel economy.

With gas prices still high, readers have asked us to weigh in on products that promise better fuel economy. We tested three: Fuel Genie, Platinum Gas Saver, and Tornado. Our advice: Don't waste your money. They don't work.

This isn't news. We've tested such devices over the years and have not found any that improve fuel economy. The Environmental Protection Agency, whose Web site lists scores of devices that the agency has tested in the past 30 years, including the Platinum Gas Saver, has had similar results.
