Magnetic gas mileage extender

I get a 25% increase by putting larger tires on the rear and smaller on the front. I am always going down hill that way. Most of the time I am just coasting.

When I run across someone who would believe a claim such as the one made by that product manufacturer, I generally don't engage in conversation with them.

Someone that stupid would be frustrating to communicate with.

OMG my dad used magnets on his gas line back in 1955. Did nothing then and does nothing now.

Many of these devices instruct you to get a complete engine tune-up before installing the device for "maximum effectiveness". The tune-up alone may account for a noticeable mileage increase. Add that to the fact that drivers tend to be more mileage conscious after installing a device, and tend to drive in a more "mileage friendly" manner, and it's not hard to see where some of these claims come from. Various truck fleet operators have noted as much as a 30% difference in fuel mileage among drivers running the same trucks over the same routes, primarily due to differences in driving style.

On a recent trip, a fellow RVer showed me a magnet that he says extends his mileage by 20%. I researched it, found many products, and many COMMERCIAL-STYLE claims, but, not convinced that it really works ...at least, not yet !

Has anyone out there used this item on a car or Motorhome and measured it's effects?

Get and install 5 of these magnetic gas devices.

I have two blocks of wood tied to my engine block and it makes my unit go faster and gives me better mpg!

JC Whitney used to sell so many mileage improvement products that, if you installed them all, you would fill your tank once, and then have to stop regularly to drain the excess fuel that was being produced.

He was not selling them. He said he got his a Harbor Freight, but I could not find one there. I feel that while he seemed to truly believe it worked for him, It may not have been more than OTHER events, stacked together that made to fuel efficiency seem better.

I suppose he also had some explanation for why the automakers didn't add this miracle device themselves? :)

Check out those hyrdogen generator kits while you're at it!

From the EPA:

You may see advertisements for devices that heat, magnetize, ionize, irradiate, or add metals to your vehicle’s fuel lines and purport to increase your vehicle’s fuel economy and reduce exhaust emissions. EPA testing and engineering analysis of such devices to date has shown no substantive effect on fuel economy or exhaust emissions.

This FTC publication about aftermarket fuel mileage devices/products is also interesting:

The bottom line is if any of these "inventions" actually worked as claimed, they would have submitted them for EPA verification and become instant billionaires. Save your money...
