Water4Gas – Three Things You Should Know

Water4Gas is a popular electronic book that has been distributed widely on the Internet amongst various groups of car enthusiasts. This increasing popularity is not surprising – after all, petrol prices are sky high at the moment and seem to be going up by the minute. The book promises to cut the petrol usage and increase car mileage by anywhere between 10 to 50%.

In fact, if you go into Google and type in “Water4Gas”, there are references to well over 100,000 websites talking about this package. It is being discussed in online forums and communities, there are pages devoted to it on popular social networking sites and content providers such as Hubpages and Squidoo.

As usually is the case, however, not everything you read about Water4Gas should be taken for granted. There are certain things to be mindful of when considering if Water4Gas is the right product to purchase and use.

First of all, the price of the package as at the time of writing is USD $97, and is quite a lot for anyone to pay for an electronic download. It is certainly one of the more expensive information products sold on the Internet. Considering that in addition to buying the Water4Gas book, users will be required to invest an additional $300 or so into the parts necessary to build the kit, it is quite a big spend.

Next factor to take into account is that the Water4Gas package is just a book. It is not a complete package, it is simply a guide on how to make a Water4Gas package using materials commonly available in shops and how to install it at home.

And the last important factor to know is that devices similar to Water4Gas may not necessarily be approved by your country’s road authorities.¬†Water4Gas¬†book mentions it, but also stipulates that the device itself, once installed, takes minutes to detach from the vehicle, in case the vehicle needs to undergo inspection.

I hope you have found this information interesting and useful. Despite the popularity of the Water4Gas kit, I would recommend everyone to consider the above points before buying the book.

MAP Sensor Enhancer – How Does This Save Fuel?

Since a MAP Sensor Enhancer is obviously a device that works in conjunction with the MAP Sensor we should have a quick look at what that device’s function is.

MAP stands for Manifold Absolute Pressure and this device actually measures the vacuum in the intake manifold of the vehicle. The level of the vacuum in the manifold changes depending on the load on the engine. This information is transmitted to the on board computer and is used, amongst other things, to regulate the air/fuel mixture.

So what is the problem? Well the on board computer is pre-programmed according to certain standards and, amongst other things, is trying to maintain an air/fuel mixture of 14.7:1. This is regarded as an optimum ratio but does not take into account that certain fuel saving techniques employed today requires a ratio with less fuel and more air (known as a lean mixture).

For instance when any of the so-called water fuel technologies are employed the intake air is enriched with hydrogen and oxygen and the best fuel saving is achieved with a lean air/fuel ratio. If the on board computer is allowed to add fuel to achieve it’s optimum mixture most, if not all, of the benefits are neutralized.

The MAP Sensor Enhancer is employed to remedy this situation. The wire that transmits the signal from the MAP Sensor to the on board computer is cut and the Enhancer is connected so that the signal now goes through the Enhancer. Since a higher voltage signal indicates to the on board computer to increase the volume of fuel in the air/fuel ratio, it is a simple matter of employing a potentiometer to reduce the voltage in the signal.

Since driving and even atmospheric conditions affects the “ideal” mixture, the MAP Sensor Enhancer is placed so it is accessible while driving and fine adjustments can be made for various situations.

I hope that this clarifies a few things and is of use to you. It should also be noted that various other devices, besides a MAP Sensor, are used in different cars and those would require slightly different techniques

Building the HHO Kits

With gas prices constantly climbing there are more and more people that are trying to figure out ways to save gas themselves. One of the most popular ways right now is the homemade HHO kits for cars. Well I did not want to be left behind so I decided to start trying it out myself. So here is a little information on actually building an HHO kit for a car.

The first thing that you will need to build is the actual HHO generator. This process isn’t too bad but it does take a while to run down all of the parts you need. One of the most popular methods is using either stainless steel wires or plates inside of a mason jar. I decided to go with the plates.

For the lid of your generator you will want to find a plastic lid to make sure that you don’t short it out. I ended up buying some lids online because I couldn’t find what I wanted at the store. This part is pretty easy and just consists of drilling a few holes and attaching some parts to the lid. I put a bubbler cap, a check valve, and a fitting to hook up the vacuum line to on the lid. I still had two holes open for attaching the plates as well.

For the plates I found some stainless steel wall plates in the electrical section at the hardware store. With these I just welded some tabs to the top of them, bent over the tab at the top and drilled a 1/4″ hole to attach it to the lid. If you don’t have a welder then just use the stainless wire instead of plates, no welding needed for that. I also used nylon bolts and washers to separate the plates from each other and keep them from shorting.

From there all I had to do was bolt the plates to the lid and attach the vacuum hose and the generator was built. I was still a little skeptical if this would work though so I had to try it out.

I pulled the 12V battery out of my lawn mower and hooked it up to the HHO kit to see what would happen. I ran the vacuum line off of the generator into another jar that was filled with water and let it start bubbling. I used a fireplace lighter to light the bubbles as they were coming out of the water. Almost couldn’t believe it but this thing actually works and it does make a flammable gas.

Seven Benefits of Converting Your Car to Run on HHO Gas

HHO Gas is a little known alternative to using just gasoline in your vehicle. This gas, commonly referred to as Oxyhydrogen, can save you 40% or more on fuel costs. Before I tell you about the benefits of converting to HHO, let’s learn a little bit about it.

About HHO Gas

HHO, also known as “Brown’s Gas” (named after Yull Brown), is created through the electrolysis of water. It is a mixture of oxygen and hydrogen containing 2 parts hydrogen to every 1 part oxygen. Not to be confused with hydrogen, HHO gas is very safe and produced and stored in a very small quantity. It has been proven to contain three times more energy than regular gasoline.

Seven Benefits of Converting Your Car To Run On HHO Gas

  • Savings – you will increase your fuel economy by up to 70%. This could potentially save you thousands of dollars per year.
  • Environmentally Friendly – HHO Gas will decrease the amount of harmful emissions your car creates.
  • Increase the life of your engine
  • Reduced maintenance costs
  • Your car already has the ability to create HHO
  • Can convert to HHO yourself for about $55 in materials
  • Cheaper than purchasing a hybrid vehicle

You can convert your car to an HHO hybrid yourself even if you aren’t a mechanic. The materials can be purchased from your local hardware store and should take you less than an hour to install. The only post-maintenance involved is the occasional adding of a few ounces of water!

HHO gas is a great alternative to regular gasoline and expensive hybrid technology. I encourage you to research this technology and discover all it can do for you!

Water For Gas – Build Your Own HHO System

The soaring price of gas is putting a crunch on pretty much any blue collar guy lately and has a lot of us becoming very interested in alternative fuels. There was time not very long ago that I was not happy unless my truck had two fuel tanks and enough power to pull down a house. Now a moped is looking pretty good and I don’t even think about picking on people for riding them anymore.

One of the most popular gas saving techniques out there right now is the Water For Gas system where you build your own HHO system. I started trying this system out a few weeks ago and so far I am happy with the progress I have made.

The first thing that I built was one of the HHO electrolyzers which was not very hard but it does require some mechanical know how. If you are the type guy that works on your car yourself then it should be no problem for you to build. Pretty much their whole target audience for the build it yourself HHO products are the blue collar guys that are used to working with their hands and have some mechanical know how.

Installing the Electrolyzer was even easier than building it. Hook up a vacuum line and a few wires and you are done. I did add in a relay so that I could actually power the generator straight from the battery. You just need to find a wire that is only hot when the engine is running and use that to power your relay.

I did not really time myself but after I had all of the parts together it probably took about three hours for me to put the HHO generator together. It took more time running around town finding all of the parts than what it took to assemble it. There is also a variety of different conductors that you can use to make the plates out of. Stainless steel wire or plates works pretty well and is what I use but there are also designs that are using titanium and copper.

With the fuel injected vehicles you also need something to lean out your fuel mixture so that you will actually save gas. There are two ways of doing this that I know of. The first one is a Map Sensor Enhancer and the second is the EFIE, Electronic Fuel Injection Enhancer.

The Map Sensor Enhancer allows you to manually adjust the voltage reading between the Map sensor and the ECU. It is a fairly simple circuit with a couple of potentiometers, switches, and resistors. If you have a little electrical experience and can read a schematic then this thing is not a big deal to make. Using one of these enhancers allows you to manually lean out your fuel mixture.

While I see why this is needed I would recommend that it should only be installed on a vehicle where the driver knows something about engines. There are quite a few people driving around that have no business being in control of the fuel to air ratio for their vehicle. It is also important that the HHO generator is running when this is used. The water vapor that is produced after burning the HHO gas has a cooling effect on the engine and exhaust system. If you lean out the fuel and do not have the additional cooling then you could do serious damage to your engine or exhaust. The major reason that I thing the driver should know something about what they are doing.

The EFIE device is a bit more complex animal. It involves a circuit board containing diodes, capacitors, resistors, pnp switches, and integrated circuits. I was going to try and build one but radio shack did not carry the IC that I needed for it and I have not bought the stuff that I need online yet. From looking at the schematic though you will need a fair amount of electronic experience to tackle this job.

The EFIE is there to perform the same function as the Map Sensor Enhancer, which is to lean out the fuel mixture, but this device ties in with the O2 sensors instead of the Map. I have not installed one of these myself yet but the installation is very basic, just a few splices. It is building the thing yourself that would get complicated.

That pretty much covers the major components of the Water for Gas HHO System although there are a few smaller items such as PCV valve enhancers and fuel heaters that they recommend.

HHO Review

Since the gas prices started going up there have been dozens of these sites popping up all over the internet. The Water4Gas guys seem to be the ones that really started it off and they are definitely the most popular.

Which HHO Guide Will Benefit Me The Most

Since there are so many of the HHO guides out there then I can’t review all of them. Most of them are just knock offs of the originals anyway. What I mean by that is there are quite a few that have just bought the books from somebody else, read them, reworded the content, and started selling them as their own. The danger here is that after they have been rewritten a few times by people that are not mechanics then you no longer know what you are going to get.

What I am going to focus on for this HHO Review is the two most popular guides. They both have their advantages and disadvantages and are both very popular systems. There are some key differences that may make one of the guides a better fit for you personally though.

These two programs are of course the Water4Gas & The Run Your Car On Water Guides and we will look at things such as price, refund rates, customer service, and technical skills required. We will start with technical skills since this is going to be a huge factor for some people.

Technical Skills


The Water4Gas system is much easier to use and build than the Run Your Car On Water system. The haredst thing about the Water4Gas system is cutting the plexiglass that is used for making their generators. You will have to have some experience at using tools and be able to drill a few holes but everything is fairly simple. Another thing in favor of the Water4Gas here is that you can get some help if you need it.

Run Your Car On Water 

The Run Your Car On Water System is going to require that you have a little more experience working with your hands and tools. There is a fair amount of cutting and some wiring so you will need to be able to solder as well. This system is just a book as well so there is not anyone to help you if you are having problems. That being said if you do have some decent technical skills then this is the guide I would go with. The end product is a higher quality and this guide costs less.

Refund Rates

I got these refund rates from a third party that tracks these kinds of sales. Both of these products are doing very well and have much lower refund rates than other products in their category.


 Refund Rate = 0.18% – That is very low. This product has an 8 week window when it can be returned and this shows that almost no one is asking for a refund.

Run Your Car On Water 

Refund Rate = 0.26% – Once again extremely low. They have the same return time as the Water4Gas so this shows that they are doing just about the same on refunds.

Some of the other products similar to these that I could get the refund rates for were between 4% and 6%.

Customer Service


Water4Gas is easily the winner here and is the biggest reason that you should consider this system if if you don’t have a pretty high level of mechanical knowledge. On top of the guides that you get with Water4Gas you also get access to their website and forum. You can ask questions in the forum or send them an email if you need help. I even had these guys offer me help when I didn’t ask. I had a blog going for the Water4Gas system and mentioned in the blog that I was having a problem with one of the parts. A couple of days later I get an email from one of the guys at Water4Gas that saw my blog and let me know how to fix my problem. I have to admit that I was fairly impressed by that.

Run Your Car On Water 

As far as I know there is not really any customer service here. You buy the book and follow the instructions. The book is very detailed so this isn’t really a problem but like I mentioned before you will need a higher mechanical skill level if you decide on this system.



There is a big difference in price between these two systems and Water4Gas is almost twice the cost of the Run Your Car On Water. Water4Gas sells for $97. Not really bad considering that with them you also have some access to support and can at least get a few questions answered if you need help.

Run Your Car On Water 

Run Your Car On Water goes for $49.97. If you have a pretty high level of technical skills than I would of course recommend that you go with this one and save a few bucks. If you are going to need some advice along the way then you might be better off with the Water4Gas though.

HHO Exposed

What Is HHO

A lot of people have been asking this question recently since the gas prices started soaring to ridiculous levels. HHO is the latest craze in the miracle gadgets that claim to increase your fuel mileage.

HHO is a gas that is extracted from water by using electrolysis. It is not steam but is an actual gas. HHO is made up of hydrogen and oxygen and is very flammable. Many sites are advertising their HHO systems as a hydrogen on demand system but the HHO is not actually pure hydrogen. It does contain hydrogen in it but is also mixed with oxygen.

HHO Gas Fact Or Fiction

This is an easy one for me to answer. HHO gas is a fact. When I first heard about these systems I was having problems believing that you could actually make a flammable gas from water. Yeah I know that they can extract hydrogen from water but these guys were talking about doing it yourself at home.

I wanted to find out if this was really possible so I built one of the HHO generators. It was pretty easy from there, just grabbed the cigarette lighter and I no longer have any doubts.

Can you double your gas mileage using one of these HHO systems. Well that is not as easy to answer there. Please read on and maybe I can help you get the answer you need.

How To Make HHO

This part is not hard to do. All you need to make HHO is a 12V battery, some distilled water with baking soda added in it, and some conductive plates. This isn’t going to be the science version of why it works. Just a simplified version of how to make the HHO gas

The first thing to do is get a jar or some other container that will hold water and take some heat. Then fill it about 3/4 full of distilled water and mix in a teaspoon of baking soda. (The baking soda works as a catalyst similar to the battery acid in your car battery)

Next you will need two stainless steel plates. I used some stainless wall plates from the electrical aisle in the hardware store. You will also need to attach some wires or some other conductor to these plates that will extend up out of the jar.

You need to keep these plates from touching each other. I used nylon bolts and washers from the hardware store. Bolt the plates together with the nylon bolts and use enough of the washers to have about a 1/2 inch gap between them.

Put the plates in the water and connect the battery to the conductors. It will start bubbling and the water will begin to discolor. Those bubbles are the HHO gas being made. Those bubbles are also flammable so if you start playing with it then be careful.

What Do You Use The HHO Generator For

The basic plan for these systems is that you install a HHO generator on your car and this will increase your gas mileage. Sounds pretty easy but after you start trying it out you will find that there is actually more to it than just this.

Most cars that are on the road today have electronically controlled fuel injection systems on them. (EFI) The computer for your car decides how much fuel it needs to send to the engine based on your throttle selection and several sensors.

Basically the computer will not care if you just go hook up an HHO generator to your intake. In most cases the gas mileage will remain unchanged and in some cases even get worse. This means that now you have to get more complex then just installing that generator.

Since the computer decides how much fuel you are going to burn then you will have to manipulate your computer into reducing the amount of fuel being delivered. There are several sensors that play a part in how much fuel is burned but the O2 sensor and the Map sensor are the ones most people are using to adjust the fuel to air ratio.

Tricking Your Computer

This is the part of the HHO system that is going to make it important for you to have a little understanding of how your vehicle works. Like I mentioned above the two sensors that are most commonly being used to adjust your fuel to air ratio are the Map sensor and O2 sensor.

The Map sensor is pretty easy to do because it sends a signal (usually at least) of between 1 and 5 volts to the computer. Lowering the voltage that is sent to the computer will result in the computer leaning out the fuel mixture. (Lean is less fuel – Rich is more fuel)

Since all we want to do here is decrease the voltage then you can easily acheive this by adding some resistance in the circuit between the Map sensor and the computer. The component that is being used for this is called a Map sensor enhancer and is made from potentiometers and resistors. No big deal for this and they are fairly easy to make yourself.

The O2 sensor on the other hand sends out a constantly changing signal, I beleive it is between 0.2 and 1 volt. In this case the higher voltage results in leaning out the fuel ratio. Since we need to add some voltage to this circuit it is a much more complex problem to solve.

The computer expects for the O2 sensor to send a constantly changing signal so you can’t just wire in something to send a steady 1V signal to the computer. Trying to do this will only result in the computer deciding that the O2 sensor has failed. When it decides that the O2 sensor has failed then it will automatically start running your engine rich to prevent the possibility of over heating. This means that your gas mileage would get worse – not better.

The device that they have come up with for manipulating the signal coming from the O2 sensor is known as an EFIE. (Electronic Fuel Injection Enhancer) Since there is no way to connect a small power supply in series with the signal wire from the O2 sensor and the fact that this voltage needs to be increased it is a bit harder to manipulate.

After I pulled up some drawings for an EFIE circuit I did not even bother trying to build one. You can buy them for about $60 so unless you are used to working with circuit boards already then I would not recommend building one yourself.

 Now here is the part where you need to be careful. Playing with the O2 sensor and the Map sensor is going to give you some manual control over your fuel to air ratio. There are a lot of people doing this so you can do it without damaging anything but you need to be aware of the risk.

If you lean out your fuel and do not have an operating HHO generator connected then there is a very real possibility of increasing engine and exhaust temperature high enough to damage your engine. This is why I would recommend that an HHO system should only be used by someone with some mechanical knowledge.

The HHO generator seems to provide enough cooling that you can lean out your fuel a little without causing damage. There is always the possibility of the generator failing though so you will have to pay attention. A clogged line between the generator and the intake manifold could cause you some serious problems.

Will It Void My Warranty

Pretty much all of the sites promoting HHO systems seem to tap dance around this question. Instead of giving an answer they will tell you how easy the system is to install and remove and how quickly it can be done.

That is because doing this to your vehicle will absolutely void your warranty if you get caught with it in there. By using an HHO system you are introducing an unmetered amount of an unapproved fuel into your engine. If they catch you there is no way that they will honor that warranty on your engine.

So Does HHO Really Work

So does it really. Honestly I am not 100% sure. There are so many factors that can come in to play with your gas mileage. Outside air temperature, driving style, altitude above sea level, tire inflation, the condition of your sensors and engine, is your air filter clean, the list just goes on and on.

Here is what I do know. There are people using these HHO systems and increasing their gas mileage. There are people that have tried the HHO systems and it did not work at all. There are several factors involved here as well. One is the skill level of the people that got it to work versus the people that did not. Obviously the more you know about cars and how they work then the greater your chance for success will be.

Another factor is what kind of car you have and what sensors it uses. For instance some vehicles use a Maf sensor instead of a Map. That Maf sensor is going to be a little more difficult to trick. The same thing can happen if your car uses an AF sensor instead of O2.

Also for the people that did get it to work. How much did they change their driving habits after installing the HHO system. How much of their gains came from the HHO system and how much came from a shift in driving habits.
