This is a brilliant web page. Scroll to the bottom to see explainations of all the ebay type myths ,magnets on your fuel lines, petrol ionizers (!?), etc My favourite it the holographic sticker that sticks to the bottom of your fuel tank!!! :headvswal

 

The MPT SmogBuster™

 

Status : Untested

fuel disc Websites : fueldisc.com and/or fuel-disk.net

If I started this paragraph by telling you that a device projected "holographic frequencies into the gas tank and changes the molecular structure of the gasoline" what would you think? Well it seems that plenty of people think enough of that statement to cough up $299 for a plastic disc with some fancy silk-screen printing on it. The idea is, apparently, that the molecularly-changed fuel (!) burns more efficiently thus giving you better gas mileage and less emissions. It's about the size of a US quarter or a UK 10p piece and is supposed to - wait for it - be taped to the underside of your gas tank. The website even helpfully suggests that superglue could be used.

From the Denverpost.com :

"It doesn't work," says Dr. Terry Parker, a physics professor at the Colorado School of Mines. Parker and graduate student John Dane of the chemistry department tested the device for 9News. "It's clear that it's just a sticker and nothing else," Dane said.

What should set alarm bells ringing with this device is that it's sold through multi-level marketing, the new buzzword for pyramid selling. The more of these units you sell, the cheaper they get for you to buy.

The best part of the sales pitch is this section :

OceanCity Network, Inc. is proud to offer a 30 day 100% money back guarantee if not completely satisfied. To qualify for a full refund, the MPT SmogBuster™ must remain adhered to the paper in which it was shipped on..

Great - so if you unstick it and use it, you can't get your money back. However, they add that to test it, you can simply duct-tape the thing to the gas tank, complete with it's backing paper. So even if the device was electrical (which the silk-screen printing might lead you to believe), putting a piece of paper in the way would prevent it from making any contact with the metal of your tank. I also suspect that trying to remove the duct tape from the fuel disc without removing the fuel disc from the backing paper is going to be next to impossible. One last point to note : most fuel tanks are covered in a rubberised underseal protection - there's no metal to stick this thing to in the first place.....

Yep, I love those pages. Very good explanations of a lot of things, and like you say, gets rid of all the myths.
