When the automobile was first invented, you can bet that there were people already selling accessories the very next day. Today, with consumers more and more concerned about the price of fuel, many opportunistic manufacturers are releasing add-on devices for vehicles that claim to boost fuel efficiency and save money. But do any of these enhancement devices actually work? Aol Autos tested a few popular options in search of answers.
The results are not exactly surprising, as none of the devices were able to boost performance to a significant degree, with some even HURTING efficiency. Here is a sampling of some of the technologies tested:
• Magnetized Line Attachment- Said to keep gasoline from clogging up fuel lines, these devices boast an increase of 5 to 20% in fuel efficiency. But according to the EPA, these products have zero effect of actual fuel economy. Examples include Petro-Mizer, Polarion-X, Super-Mag Fuel Extender, and Wickliff Polarizer.
• Air Vortex Technology- Some products, such as the Tornado Fuel Saver, claim that their product’s effect on air mixture in the engine can boost mileage and horsepower. However, testing showed that there is no measurable improvement on either.
• Fuel Additives: These companies claim that simply adding their product to you car’s gas tank will cause fuel to burn more efficiently and increase mileage. The EPA has tested several of these, including Bycosin, El-5 Fuel Additive, and Dyno-Tab Fuel Booster, and found no positive effect.
Other methods tested included PVC “air bleed” technology, vapor bleed devices, ignition devices, fuel line heaters, metallic fuel line devices and oil additives. You can read the results here.
When it comes to saving money on fuel, a gimmick is never the answer. The best way is with good fuel management practices, starting with a fuel solution that manages, records and controls your fuel spending. And that’s the truth.
