Florence Sigusmundi - Without: 14MPG    With Gas4Free:  25MPG

I personally installed this system no problem at all and after the first week I increased my mileage by 60%.    I am now known around town as the Green Florist who drives the truck run on a water-hydrogen system….

Tom Baird - Without: 10MPG   With Gas4Free: 32MPG

I drive a rebuild muscle car around town in the summer - a gas guzzling Chevy Camaro.  It consumes nearly half a tank of gas in just one afternoon.

Unbelievable!  I increased my MPG by almost 300% using the Gas4Free system.  I could not believe my eyes when I looked at the dials.

 Brian Farrelly - Without: 16MPG   With Gas4Free: 28MPG

I have been driving my 1985 Ford pickup since it was brand new and I have never seen it perform better…Installing the hydrogen on demand system seems to have given my entire truck a good tune up. Not only does it smell a lot better but it no longer spits out clouds of black dust.

H. Halloran - Without: 26MPG    With Gas4Free: 44MPG

"...passed the smog test with ONLY your product installed and no catalytic converter."

In Florida our cars have to pass a smog test before we can drive them.  This means that almost everybody has a catalytic converter..Now that is what I call saving the environment. 

By the way we are both in our 70's and the whole deal only took us an afternoon to install.

Richard Burry - Without: 20MPG   With Gas4Free: 39MPG

"I personally installed this system no problem at all...the first week I increased my mileage by 100%"…I drive a 1993 Acura Legend with over 350,000 miles on it.  You have saved me a oodles of money. 

 I have more than doubled my mpg.  The car runs a lot better too.  I can finally hear the radio.


Lisa Bond - Without: 27MPG   With Gas4Free: 47MPG

My brother installed your hydrogen on demand system in my car in less than an hour and a half and it has gone from 27 mpg to 47 mpg. 

Maybe this is one way we can get our boys out of Iraq!  Thank you.

J.R.  "25% More Mileage - 2005 Nissan Sentra"
MY Water4Gas unit I have on my car is working. So far I have noticed a jump in mpg from 24ish mpg to 30ish mpg I am running it on a 2005 Nissan Sentra

A. C.  "Higher Performance - Jaguar XJ6"
I drive a Jag XJ6 and my average miles per gallon has been 16-18 miles.
Now device is installed I am experiencing 19-24 miles per gallon.
In addition I have more "pep" on my accelerations. It feels like I have a totally different car with more power and smoothness.

M. Porter "38% better mileage - Dodge B150 1999 Cargo Van"
I live in Montana and do a lot of highway driving and in city driving. I drive a 1999 Dodge B150 cargo van, 318cu engine with throttle body fuel injection and air conditioning. I have a 35 gallon gas tank and I burn regular unleaded.
After a long trip on the highway my trip meter would average between 350 and 375 miles per tank. After using the GST's my gas mileage is almost 500 miles per tank !!

E. S. "Everybody should have this technology!"
A friend installed this gizmo in my truck two months ago. After 30 seconds first start I noticed that the engine became soooo quiet. At first I thought the RPM went down because of the water, but no, the device has definitely changed the way my engine works - it does not ping anymore! FOR THE FIRST TIME  I can listen to the radio at low volume or talk on the cellphone without shouting!

On road tests I got "only" +13% improvement on MPG, but the company gave me a solution to improve that to at least 25% with small modification.

J. H. "My car continues to improve... Feels like a new car!!"
My car is a 1986 Subaru GL. I bought her originally in 1989.  Two weeks ago I agreed to have the gas saving device put on my car. Immediately I noticed that the engine was much, much quieter and smoother. Feels like a new car!!

We did a test drive on the car with and without the device. The results were spectacular. The Subaru does 32.8 miles to the gallon. With the device - which is only the very basic fitting - the Subaru did 36.8 miles to the gallon, a saving of twelve and a half percent. What was really noticeable on this test drive was the difference in the quietness of the engine and how the car picked up much easier with the device installed.

B.L. "Passed smog WITH NO catalytic inverter!!!"
A friend of mine installed one on an old Cadillac. His catalytic converter had gone bad so he removed it and took it in for emissions testing.

After the test the mechanic came out and said "Boy you sure have a great catalytic converter on that car!"

 Bill Lang  "Mileage gain 48.5%!"
My friend Don C. tried out the charged water system in his 1993 Pontiac Grand AM. Went from 28 MPG to 41.6 MPG.

 N.G. "Mileage gain 68%!"
Wanted to report that my friend, an 85 year old mechanic, installed a Hydrogen-On-Demand system on my car and it went from 28 mpg on the highway to 47!
