One of the questions is how often do you have to replace the $15.99 catalysts....................what if it is every day.

Lets see $299 +$16 worth of catalyst [per day week?] saves how much gasoline per year

"The government does not allow us to make specific guarantees regarding the actual mileage savings you will receive while using the HydranOx 5000. That depends on various factors including: the operating characteristics of your particular vehicle, the type of driving done (i.e. city vs. highway), your personal style of driving, etc. This is an electrical device and once the the unit has been installed and used, it is no longer resellable, so refunds are limited but satisfaction is guaranteed. .......................WE DO NOT GUARANTEE FUEL SAVINGS IN VEHICLES BUILT BEFORE 1996 ALTHOUGH WE HAVE FOUND THAT SOME HIGHER END MODELS DO RESPOND.WE ARE HONEST AND UP FRONT ABOUT THIS UNLIKE OUR COMPETITORS. YOU WILL GET MORE HORSE POWER AND BETTER PERFORMANCE WITH OLDER CARS BUT YOU WILL PROBABLY SEE NO INCREASE IN GAS MILEAGE."

The you are a total sucker statement

HOAX!

You let TV reporters tuen your car.

"HydranOx 5000 feeds your engine hydrogen (over 30 cubic inches an hour)."

This is insignificant, especially in highway use. If it were significantat all (say 5% O2 increase), you would have to recalibrate your MAF to keep from a too lean condition melting your pistons.

Having too much hydrogen and oxygen gas in the combustion chamber will have an adverse effect on the vehicle. After hydrogen is burnt, the residue is water, so the more hydrogen the more water, which is not good for the vehicle. Additionally, when you recombine hydrogen and oxygen under pressure, like what happens in the engines cylinder, a portion of the two gases converts into water vapor before the burning process, so even more water vapor goes out the exhaust. Oxygen also has a negative effect on the vehicle. After the extra oxygen leaves the exhaust ports, one of the many oxygen sensors pick up on that oxygen, and sends a lean signal to the computer. Which in-turn increases the fuel to burn the oxygen better trying to keep the perfect burn ratios for the vehicles emissions. So you will have to increase the hydrogen for fuel savings which adds more oxygen and water, also large amounts of hydrogen can throw off the vehicles timing. So there are many things that will have to be recalibrated like timing, oxygen sensors and the computer to except the changes, which is against federal and most state laws if tampered with. Not to say what the vehicle is supposed to do with all that extra water coming out the exhaust ports, for the fix, will have to be a new stainless steel exhaust system. And what about the cylinders and the catalytic converter they don't like that much water going through them either. So think twice before you buy or build a hydrogen generator that will harm your vehicle in many different ways.

That sounds like you're going to have to do extensive engine and exhaust modifications just to coax an extra 10 mpg out of your car.

Doesn't look like it's worth the hassle. 92 was $2.99/gal yesterday, not that bad.
