Complete HHO Systems
"I'll keep this short and sweet, my generator arrived today and I am absolutely floored with the professional build quality or your products, as well as the level of detail in your controls and online documentation. You're setting the bar for this industry."
D.R. Canada

"Got one from ya a few years back for my 70 chevelle 454 works great! ya probably won't believe me but the thing doubled my mileage had to check it a few times thought I was seeing things, The mileage went from 8.5 to 17 mpg for mod 454 I thought that was pretty good"

"2 dry cells, reservoir, 1 quad digital EFIE, 1 reg digital EFIE, 2 MAP enhancers (dual style). I have them almost 2 years and the products are working fine. Good quality products at a reasonable price and technical help. Low maintenance, good quality. Good installation instructions and troubleshooting info. Longevity and low maintenance, and consistent performance. The MAP enhancer is especially good compared to the one I made because it has a wider adjustment potential. The generators don't discolor the water like the wet cells did. I also like the dry cells because it circulates the water and doesn't heat up. Thanks for the tech support."

"31mpg! CITY! 100% increase! 2000 Toyota 4 Runner, 4 cyl. 2.7litres. I'm quite amazed. I did a long road trip, and quite skeptical, had to pull over every 40 miles or so to test results by refilling at the next gas station. I got 30mpg's highway, and when I dialed my EFIE, 31.5mpgs IN CITY. Awesome stuff guys. I'm getting 100% increase in mpg."

"I'm seeing about 25% increase in fuel economy so I know the system is working. My vehicle is a 2002 Dodge Ram 1500 with a 5.9L gas engine."

"I used the HHO system very effectively for about 2 years on my 85 Mercedes 500SL. I enjoyed this experiment and consistently got 25% more mileage when the system was in use. It really helped when you have an engine that only gets 18 mpg it was a great experience for about 4 years. Keep up the innovative work. I think you are part of a grass roots effort that is pushing the big auto makers to finally start taking mileage and the environment seriously."

"I have one of the systems currently running on my Dodge truck (440 cid), I am getting better than 20%, although I do a lot of in town driving and it messes with the fuel efficiency. On the open road I get much better. Running less than 20 amps most of the time."

EFIE's and Electronics

EFIEs and Electronics
"I have been using your digital and analog EFIE's for more than 3 years, and yes, they work well. Because you are very serious about your work and product, I believe they are the best on the market! Your EFIE's are very well build, easy to install, nice addons such as probe holes. Gains vary between vehicles but 15 – 30 % average. These digital EFIE's are hard needed when you install a watergas system in a fuel-injected petrol vehicle. They are well thought-out, well designed and well build and made to last a long time. I have not seen better quality EFIE's on the market! I'm sure that the other products Fuelsaver-MPG sell are of same the quality."
F.G. Netherlands

"I use many of your EFIEs, and a couple of MAP/MAF devices about 4 years. They are working without a problem. I get about 40%+ fuel savings with HHO. Quick good service - get what I order. Operational always, with good installation instructions. Usually, with older cars, they are not really needed. But, since the inclusion of fuel computers and lambdas on vehicles, the need for oxygen sensor control is very necessary, requiring EFIE’s and MAP/MAF devices to regulate the proper fuel/air (HHO) mixtures. FuelSaver-MPG products have never let me down and the price is right."
D.G. Moscow

"I am using a digital and analog EFIE on a 2002 Subaru. I have been using them for about two years. I get about 25-30% gain. I found your company on line. It appears you folks do a good job. Qualities: Follow thru, quick turn around, quality product, good value. Review: I began experimenting with HHO in 2008. I have always believed that we spend way too much on fuel and find enjoyment in cutting the costs down thru other alternative methods... namely Hydrogen. Nay sayers think it BS. I know there are MPG gains to be had."

"My old truck passed the Texas exhaust inspection after failing the day before without it. I replaced the o2 sensor and added one of your EFIE units. I have an old 1995 Chevy 3/4 ton four wheel drive pickup that I love."

     "My mileage went from 24 to 30 mpg, and I think there's more to go from here!"
     "Finally, HHO Products and SUPPORT that make this work for everyone."
     "I'm glad I can finally show my friends this HHO stuff works!"

This applies to our HHO generators as well as any related electronics and accessories.

What to Expect

     When all installation and use guidelines are followed, every customer
has the opportunity to benefit from fuel saving technology.

     When applications are connected with internal combustion engines,
the presence of our fuel saving devices have many positive effects:

     The faster burn rate of hydrogen helps to further complete the
combustion process of many liquid fuels.

     A more complete combustion results in more power, lower unburned
emissions, and a cleaner running engine due to fewer carbon
deposits left on valve and piston head surfaces.

     Many customers translate these advantages into fuel savings and
increased mileage per tank of gas.

     Advanced HHO is supportive of all enthusiasts interested in fuel saver
technology, and we have a multi-year history of good results.

     Some products are not legal for street use in California, USA.

Satisfaction Assurance

     We want to assure you any purchase you make from us will operate
as advertised when installed properly. It is also fair to say that HHO is an
emerging and experimental activity and therefore we can not guarantee
all applications will be successful.

    However, we find that when all installation and use guidelines are
followed, every customer has the opportunity to benefit. Our success is
based upon a standard procedure for installation. Additionally we
offer a procedure for quality control and troubleshooting.

     Should situations arise around this statement, we request the customer
to put reasonable effort into installing the product properly and to go
through the standard trouble-shooting checklists we offer.

    An exchange or refund is possible when all parties have demonstrated
proper effort to troubleshoot and work together, and only follows the return of
products in question with their condition showing acceptable, normal use.

Return Policy

Our return policy is fairly simple. Providing you have not purchased an incorrect system for your vehicle or need to exchange your product for one more appropriate, you can request a refund by following the three basic points below:

1)      We hope for you to contact us within 60 days of purchase to advise us of a possible problem. If longer than 60 days, we can still work with you, but our interest is to help customers quickly to keep them satisfied and ensure they have positive results.

2)      Should a desire for a refund be communicate due to system performance issues, we require the customer alert us of this and go through our basic trouble shooting steps to find the problem. As these systems are user-installed it can happen that simple installation steps are skipped or misunderstood and can result in limited results. These can usually be corrected by reviewing the installation process together and finding the area that didn’t follow along with the installation instructions properly. We have several installation experts to help you.

3)      If after these steps have been addressed and a refund is still desired, we will issue a Return Merchandise Authorization number and you can return your system to our fulfillment warehouse. The merchandise must arrive in reasonable condition pursuant with standard usage and not deliberately tampered with or damaged. A refund will be issued less 20% of the purchase price to cover administrative handling and restocking fees. Any refunds issued will be received within a 30 day billing cycle, but is often handled much faster.

In this way we work to focus on the positive results of our systems and eliminate the few times we have customers who for one reason or another cannot successfully get their systems installed and working properly. We believe in fuel-saving technology and all our customers should feel confident their purchase is of the highest quality and level of effectiveness.
