Alright, I have been seeing more and more of these things pop up with pretty impressive results. I also have a friend who installs them and swears by it. What do you guys think? I put a lot of highway miles on my Avant and something like this would make a world of difference on how much money I am spending on gas a month. I am currently paying around $250.

All of those kinds things are scams.

At least provide some back-up.

The only one that makes even a little bit of sense is the aquatune system. Even then it is very debatable.

THE MORAL OF THE STORY
We've tested nowhere near all of the fuel-saver gadgets on the market, and I'm sure purveyors of others will be waiting in our lobby soon. But not one of the items we tested worked. At all. There's no ignoring the laws of physics, people. Your vehicle already burns over 99 percent of the fuel you pay for. Less than 1 percent is squandered as partially burned hydrocarbons and carbon monoxide before the exhaust hits the catalytic converter for the last laundering. Even if one of these miracle gadgets could make the combustion process 100 percent complete, the improvement in mileage resulting would be 1 percent. Any device that claims quantum-level increases needs to be examined with considerable skepticism.

PM has since admitted that their testing was flawed since they didn't follow instructions.

If you want great gas mileage then fit tires that are 195mm wide and rated for 80k miles. That got me 30-35 on the open road.

The Fitch catalyst worked in every test I've seen so far. They tested it on Horsepower TV and it made more power on less fuel.

Ok.

Any high school chem class will teach you that you can't create energy from nothing. (Which is what these products claim) These actually use more energy than they can possibly produce. Electrolysis, splitting H2O onto 2H and O, is a very inefficient process. Then the "HHO" is injected into the intake for the engine and burned, most of the energy is released as heat. Then the the "HHO" is recombined into H2O which requires most of the potential energy that isn't released as heat, leaving very little left (if any) to do any actual work.
