Magnets are quite interesting because they have the ability to attract and repel due to the energy they create. We can all probably remember science experiments in school that dealt with magnets. They were actually very fun to play with and to see what they could do.
Magnets of all different sizes are used in our society for a variety of things. We use them to keep things on the refrigerator, to search for items, and to operate various types of devices. Many people view magnets as something scientific though so they assume it may be logical to try using them to save money when it comes to fuel costs.
Many consumers like this idea because they aren't adding anything to their vehicle in the form of a liquid which often makes them worried. The magnets can be added or removed any time you feel like it. They like the thought of being able to get results without the risk of ruining some part of their engine.
There is also the fact that you don't have to remember to buy them all the time. With additives you need to get a good supply of them and then remember to use them at the right times. With the magnets you can simply put them on once and then not worry about it again.
Magnets that are offered for reducing the amount of gas that your car uses will cost you between $15 and $40 so that isn't too much of an overall investment. They can improve your gas mileage ever so slightly but not enough that you will get any real savings out of it. We are talking 10th of a gallon when it comes to measuring the benefits.
These magnets are secured to the fuel line and are believed to change the molecular structure of the gasoline. As a result the types of metals that are used to ionize the fuel will no longer be there. This may all sound good in theory but the reality is that it doesn't do anything for your gas mileage that is significant enough for you to save any money.
Magnetic gas saving products often have the biggest claims when it comes to how much gas you can save. Many of them boost about a savings of 20% -25% but the testing on such products hasn't shown hardly any benefit at all, let alone something that substantial.
There is a popular TV show called MythBusters where they take certain products and test them out to see what the results are. They did a show about the use of magnets to increase fuel mileage a while back. You can see parts of it on their website if you missed it.
Several different brands of magnets advertised for saving gas were tried out but the results were similar with all of the ones they tried. They were able to control the variables and tried the use of the magnets under a variety of different conditions.
They didn't find them to be difficult to put on the vehicle or to remove. They also didn't find them to offer any significant benefit in the area of gas mileage from them. So the best bet is to skip these types of gas saving devices and use your money for something else.
