Fuel saving devices- magnet and catalysts

Magnets & Catalysts

These types of devices supposedly "line up the fuel ions" in order to make the fuel burn more completely and efficiently. They wrap a magnet around the fuel line and as the fuel passes by, it changes the burn properties of the fuel. The only problem is, magnets have no effect on fuel or the fuel "ions". I tested one such product that sold for over $300.00!!! The other type is a fuel catalyst. This type fits into the fuel line and as the fuel runs through it, special materials cause the fuel to "improve fuel performance in the areas of decreased fuel consumption reduced exhaust emissions and restored fuel properties."

Southwest Research Institute San Antonio Txtardec Fuels And Lubricants Research Facility (SwRI/TFLRF) tested three such devices and found "Under the conditions tested no fuel economy benefit was observed for the baseline device".

Next time around I will go into some other types of devices. but before I go let me leave you with this: the best way to improve gas mileage is to keep your engine well-tuned and check your tire pressure every time you fill up.

Fuel saving device- fuel additive

Fuel Additives

There are many types of fuel additives that make the same claims. These work with varying degrees of effectiveness. The most common are the fuel system cleaner types. These products claim to clean the fuel system and help keep fuel injectors operating at peak performance. It's a good idea, and some do work, but most are of questionable effectiveness at best. Now the rub here is if you live in a state that mandates all fuel sold contain a 10% ethanol blend, as I do. In that case, you are already getting the active ingredient in a fuel line cleaner: ethanol. Ethanol, or methanol, is also the ingredient used in fuel line antifreeze.
