Finding ways to save money on gas is smart and important, and more and more people are looking for fuel efficient tips as gas prices continue to rise.

As a result, it may be tempting to purchase a so-called “gas-saving” gadget, engine add-on or secret solution. Some devises may go for a couple of bucks and others may cost hundreds – all of them promising to save you money in the long run. Unfortunately, many gas-saving devices do little but waste your time and money.

A Popular Mechanics article explains how PM auto gurus tested an assortment of gadgets. Here’s what they found out:

  1. Magnets: Fuel-line magnets claim to break up fuel molecule clusters so gas burns more efficiently, but gasoline molecules are not magnetic and the test showed no effect on gas mileage.
  2. Vortex Generators: Two devices that are supposed to increase airflow did the opposite, reduced horsepower and increased fuel consumption. They could also damage your engine.
  3. Engine Ionizer: The test for this device could not be completed because it melted and set the engine on fire!
  4. Vapor Injectors: Claims to increase gas mileage up to 300% but the test showed the fuel economy was unchanged.
  5. Water Injection: After $400 and several feet of vacuum line, the test showed 20% poorer fuel economy.

So PM’s research found these gas-savings gimmicks had no positive effect on gas mileage, some had a negative effect on gas mileage and one (certainly dangerous) device caused severe damage. These products and others remain on the market and many well-intentioned consumers may be fooled into purchasing them.  

Do you think you’ve found a secret device that may be the real thing? Before falling for a gas-saving scam, see if it’s one of the many products tested by the Environmental Protection Agency. The EPA has tested about 100 products of which only six had a slight effect on gas mileage. Furthermore, no matter what the seller tries to tell you, the FTC reports that no government agency endorses gas-saving products for automobiles.

There are surefire ways to cut down on gas consumption and they are probably recommendations you’ve heard before:

  • Get regular maintenance and tune-ups
  • Drive conservatively
  • Don’t carry around extra weight in the backseat or trunk
  • Keep your tires properly inflated
  • Get a fuel-efficient car
