Why don’t all cars have them fitted as standard – great idea

This is total and complete nonsense. There is a VERY LONG history of bogus fuel mileage boosters for cars. Heck there even used to be a “pill” to turn water into gasoline.

If it is so easy to boost your gas mileage %18 why don’t the car manufacturers do it in the first place.

Rule #1 if it seems to good to be true, it probably is. Don’t be a sucker.

Wow — what some people will fall for.

The ECU is shielded and has its own regulators and resistors — it’s not receiving interference — and even if it were, plugging something into the electrical outlet won’t help a thing. Is the author of this site getting some kind of kickback? Why even post something so obviously intended to rip people off??

I go to this site about three times a week, but after this — wow.

I knew I should have called magic stick. Thank you all for you input.

“An independent automotive testing service showed the unit increased an automobile’s average fuel efficiency from 23.8 to 28.1 miles per gallon in two weeks” Ha! Who was this testing service, how accredited? and where is the full report?
Another totally bogus device, as it’s tapped onto the end of a current outlet it can in no way regulate any current flowing to the ECU. Regulation of that is accomplished within the ECU’s circuitry, which already has a voltage stabiliser and resistors.

If the inventor had come up with something that really worked, he’ds have sold the invention to a car manufacturer for untold millions, rather than selling gadgets on the net.
