anybody heard of this or ever tried it. Its a one time install of a fuel filter looking thing that improves fuel quality and octane rating and supposed reduced emmissions while improving performance as well as mpg from 1-2.5 mpg more. I saw it on truck universe today on the speed channel, and i looked it up. its 175 dollars for the one for a JK, and well, if it works, i'd buy it, if not, i won't. so any input is appreciated

 

There are several threads talking about it. I would have to say that if it sounds too good to be true then it probably is.

 

haha, i'm guilty of not searching first... i just did a search and saw the other threads, i guess i'll hold off on it and just keep saving up for the ripp supercharger in order to have more power... uhh i mean, save on gas milage

 

I'm getting a flux capacitor for mine. I'm gonna travel back in time and buy gas for 75cents per gal. I'll sell you the plans for $174

 

the guy at 4wd has one on his 4 door JK, he says he noticed a slight increase, I dont recall the actual mileage...

He said it was easy to install

 

I believe JP magazine claimed an increase from one they installed as well (an article testing various MPG increase "gimmicks")

 

It doesn't work, it doesn't work, it doesn't work. I don't have to read a single test report to know that it doesn't work. All I have to do is be vaguely familiar with CAFE and environmental laws. And to realize that the auto manufacturers have a very tough time complying with those laws. If this device gave any significant improvement in gas mileage and environmental emissions, every manufacturer selling in the U.S. would include one standard on their vehicles. End of discussion. Except: The next miracle device that comes along, if it REALLY works, it will be standard on all new cars. Buy that one.

 

I too have seen these "Gimmicks" you speak of(A.K.A. I have that issue too), and I think that Fitch has a pretty good product, but that is just my 2 bits. JOE>

 

If stuff like this worked like the companies say they do, this stuff would be on every car and truck made in the world.

 

Alchemy was done and over with 500 years ago people. Go ahead a buy one, cut it open and send a sample of the contents to a lab and have it analyzed. Here is a quote from their site:

"The catalyst is a composite of a number of metals formed into an alloy by a propriety process."

Needless to say, this sentence makes no sense. The word "composite" and "alloy" mean basically the same thing; a mixture. Typical gasoline itself a mixture of aliphatic hydrocarbons, tolulene, benzene and ethanol. While its hard to believe a "catalyst" reaction could occur at the high rate gasoline travels through fuel lines and the Fitch Fuel Catalyst I think there is something going on here. The only metal that could in fact impart the fuel with an octane increase is Lead. This would explain why initially users report a slight increase in mileage and then poor running conditions as their catalytic converters get ruined.
