Raw data, no changes, 100% truth, Negative advertising, but truthful. Hydrogen Garage is here to help, not deceive. Also note, most will post a negative comment to complain, rather the guy who gets good results, will not comment. Please send us your results so we can keep adding to this page.

2005 Chevy Impala - 32 to 48 MPG. 50% gains!

2008 Chevy HHR - No results. The FS2 made no change for this car. It was getting 450km per tank. The last tank was 410, seems worse.

Buick Century 3.1 engine with a HHO booster added. Our results with the FS1 chip were good, the engine ran well as expected approximately 20%.

Dodge intrepid 1996 - I did not find it made any difference to my mileage at all. My normal mileage is 26 mpg. I tried it many times I have a scanguage.

The two FS2 circuits that I bought from you work great, 10 mpg gain on the Dodge & 8 mpg gain on the Saturn. Thanks

Suzuki 1998 Baleno & a Esteem 5 door hatch & a Holden Commodore 2000 - Dear Staff and Bros, Have been installing the FS 2 -HHO Flasher into 2 vehicles. Both have improved performance immediately. We have installed a Hydrogen Cell 33 plate 5 neutrals , 445 nm system to the Suzuki. The owner is testing the vehicle at the moment with 2 tanks of fuel and will give us a KM to Litre percentage shortly. No problems encountered as yet God Bless.

Chevy S-10 Blazer, 1996 = I installed the chip and a C3 cell in addition to the cell of my own design on my Blazer before we took a trip to Mexico from our home in Colorado. I had better mileage coming out of the mountains and across the Navajo res. than normally, but after Flagstaff and down to sea level, it became worse. I am now at our place in Baja and have disconnected the chip. What I noticed with the chip is that it seemed to lean out the injectors, but this caused a loss in power and I had to compensate with more pedal pressure, resulting in more fuel usage. I am now testing the mileage without the chip for a comparison during our stay here and subsequent trip back to Colorado. I feel the chip is working but I still get too lean codes. I have my scanner with me and the mileage has decreased. Will let you know the results when i get back home the end of this month.

Dodge Neon 1997 - I have the unit with only a water bubbler since my hydro cell is not yet ready. However, I noticed that my car runs smoother and I feel a little more power. I was expecting my car service light will turn off but sometimes it does but it also comes back on again. I would like to try the upgrade to the FS2.

Ford f250 99 diesel truck - My installation went well, 1st tank of fuel shows declining fuel economy. I haven't installed my hho gen. yet and I was wondering if I should reset my chip .What would you suggest?

Yes reset it, when you change things ( add a HHO booster)

Dodge Magnum 2008 & Saturn Ion 2007
The Magnum was getting 18 to 20 mpg. with hydrogen -24 mpg. then with the FS2 - 35mpg. and I think it will do better, the hydrogen is cutting in and out because of a 20 amp re setting circuit breaker. The Saturn was 30 to 32 mpg. no improvement with the HHO.Then with the FS2 38 mpg., but I am having a problem with not enough HHO production. I am working on that, I feel that I will be abel with more HHO the mileage will jump to 50 mpg.

Ford Expedition 2004 = I get between 2 and 3 MPG. improvement with the chip. I am considering one for my 2004 GMC Sierra.

Chevy Astro Van 1997 =I'm into only a weeks worth with the FS2. I do notice a substantial increase in HP & torque. I don't notice much in the way of better MPG as yet,C but that may be cuz I'm driving it harder, cuz it's fun having more power. I'm using a 1 lpm HHO boost also. I was getting higher MPGs I think using the FS1 than the FS2HHO version, but without the additional gain in HP. I also have my air intake reduced to tell my ECU that I'm at a higher altitude, so maybe that's why I'm not seeing a larger increase in MPG., but it was that way with the FS1. soooo, I'll post the results if any after removal of said intake-blockage..

Chevy pickup 4 wheel drive 2004 = I have the FS2 installed on my truck with the 5.3 engine.The best mileage I have gotten with it is 21 mpg on a 40 mile trip highway and some city driving with hho on. I had the FS1 on before without hho and the best I got was 19 mpg. I get 18 mpg stock.

GMC Sierra Truck 2006 = I'm not a very exacting person but I do know this device is saving me money the truck idled at 900 rpm's, its now slower at about 500 rpms.

2000 Intrepid = The FS2 made no change for this car. It was getting 450km per tank. The last tank was 410km seems worse.

Dodge Ram 1500 4.7, 2002 FS1 results = I wanted to let you know that at 15A we were at 15% but now at 11.5A we're up to 30%! I guess the FS2 has a limited ability to compensate. Anyway, there is a guy with an FS2 that says he's at 21A, 6MMW, and from 19MPG up to 26. I don't know if it's true- but he does have an 'HHO drier'. What do you know about these? There was a guy a while back selling driers on e-bay that swore they were the key to lasting gains.

BMW Z3, 6 cyl., 2.8, 1997 FS2 results = Used to get 20 MPG on a average. Now gets around 25 MPG on a average with the addition of a cell, 1.5 lpm, 15 amp draw & FS2 HHO Edition circuit Engine has more horsepower and can buy the cheaper grade gas. Square wave pulsed DC makes the better ortho hydrogen, in which is like adding 120 octane gas into your air mix.

Saturn Ion , FS2 results = 40+ MPG. I was very happy with the installation on the Saturn Ion I am up to 40 + and am expecting another at leased 5 to 10 mpg when I install the cell exciter on the Dodge. I enjoyed talking with you yesterday and look forward to doing it again.

Chrysler Intrepid, 1996 , FS2 results = 409.000 kms no fuel cell have't tried with a cell yet but will inform when I do, so far so good. 23 mpg to 34 mpg at 120.00 kmh 70 mph.

Ford F150 truck , 2002 , FS2 results = It has been a few tanks of gas and I am getting the same mileage as before but I have not added the hydrogen generator. One thing I noticed is that the response of the accelerator is much better, like a new car.

Ford Explorer 1998, 4x4 4.0 litre I already had HHO booster, a dual O2 EFIE & MAF enhancer. After installing the FS2-HHO-Edition, I gained an additional 2 mpg.. Original mpg. was 16.5, now getting 22.

2007 Cadillac No improvement in gains.

Install tips :

If you change anything in your set up, (add a cell, or change wear you put the intake hydroxy gas hose, etc. ) You should push the rest button on the volo blue box. Only do this when the engine has warmed up and in "closed loop" mode and idling, push the reset button. Most cars start up in "open loop" until operating temp. then switches over to "closed loop mode" ( 5 minutes or less) How do I know it is in "closed loop"? Buy a $160 Scangauge II, a gas saving mileage indicator on the spot. Ask any one who owns a Scangauge II, they will tell you that they love that thang.

Remember #4 pin is black wire, ground, on all US OBD II's and the pin #16 is positive, red wire.

pin #4 and #16 are the same on all these protocols.

15 good results, 3 bad results = 80% positive

Do you have the wires hooked up correctly? Check again, a few customers mange to hook it up, upside down. Follow the instructions here.

Please send us your results so we can keep adding to this page. We WILL NOT put your name or city or nothing, just facts from you , your make model year car & results for MPG savings? HP increase? We want to pool as many results as possible.

Some get the circuit installed and experience good MPG savings the first fill up, after that it goes back to normal. You may have to reset the reset button at each gas fill up, and always reset in idel, all warmed up. Takes 30 seconds to calibrate and the lights go steady and you start driving again.

Warranty Limitations and Return Policy
Your Satisfaction is Guaranteed!

In the rare event you don't notice a difference immediately, please reset the chip as indicated in the instructions and try again. Depending on the vehicle, it may take up to 120 miles of driving before some ECUs will accept the VP12's patched values. This safety feature prevents an ECU hiccup from impairing the entire system. If you've tried everything and still don't notice a difference, return the chip within 30 days and we'll be glad to provide a full refund of the purchase price. Please contact sales@voloperformance.com for RMA before sending return. Items returned without RMA may be delayed.
