Lately, many companies has been advertising an oxy hydrogen kits for automobiles. These kits separate oxygen and hydrogen from water. Then injects the two gases into the throttle body of the vehicle. The hydrogen gas causes greater combustion and burns move of the injected fuel. These companies claims by doing so, more power is extracted and the vehicle will save on fuel.
Dan mentioned one of these product's web-site to Sasha and I. While trying to grasp the technical theory behind it, Dan has grown inpatient and ordered the device. We now look forward to receiving it and testing it with our instruments.
We have all been anxiously waiting for Dan's Oxy Hydrogen to arrive. It did two days ago. Upon opening the box, we gleamed over all the parts for hours. The kit comes with instruction on CD. My first impression is that all the parts can be put together from Home Depot. But the workmanship is excellent. I would absolutely buy the kit, rather than putting it together myself, if it works! And that is really what everyone is thinking, the bottom line; whether it actually works as it claims.
Dan has a 1999 Saturn SL2. It is just an econo mobile that get him to and from work. Unlike Sasha and I, Dan doesn't modify his car and only fixes it when it breaks down.
The SL2 has an 1.8 liter engine. So Dan bought the Oxy Hydrogen AL-12 unit meant for engines up to 2 litres. The kit that Dan bought is from this site: Oxy Hydrogen The Ultimate Fuel Saving Device
The SL2 engine bay is packed. The only way we could get it to fit is to remove the intake silencer that is mounted on top of the fan and connected to the air filter box. We secured the unit with zip ties for now, and didn't poke the switch and amp meter through the firewall. We mounted the device temporarily for this test. If the device proves to work, then we will mount everything permanently.
The Oxy Hydrogen web site recommends distilled water as the hydrogen/oxygen source and recommends lye as the catalyst.
The instruction that came with the unit recommends tap water and lye. It mentioned that you can substitute baking soda for lye, but lye will produce result.
We didn't have any lye, so we used distilled water and baking soda. If this device works, then Dan will start using lye.
Dan filled the unit with distilled water up half way. He turned on the car and the unit. We all watched the amp meter. He filled the unit with baking soda until the amp meter showed 20 amps.
Our test plan was to fill the car up with gasoline, take a approximate thirty mile round trip back to the gas station, fill it up again, log the mileage and the gallons of gasoline used. Then we'd repeat the run again with the oxy hydrogen unit, using the same gas pump.
There are two reasons why we choose to conduct the test in this manner, ratter than the typical full tank daily drive test.
One, there are always controversy on the daily average test. There are too many variables that could change over time. Temperature, humidify, speed, traffic, route to and from work, tire pressure, etc. We could eliminate most of these variables, if we could perform a test within a short time span.
Two, a short test allows is to repeat it several times, if necessary. It's helpful if we screw up, or if we decide there is more to test.
The first route we came up with is round trip from Loma Linda to Ontario. But we Settled on the highway 30 loop. We world start at the Valero gas station right beside I-10, head toward Redlands on I-10 east, interchange to 30 toward Highland, interchange to I-215 south, finally interchange onto I-10 east back to the gas station.
We performed the test at approximately 11 PM to avoid traffic.
The entire loop is exactly 21.5 miles. The odometer is constant and shows exactly 21.5 miles on both trips.
The first fill up, without oxy hydrogen, is 0.86 gallons. It translates to 25 MPG. The second fill up, with oxy hydrogen is 0.594 gallons. It translates to 36.195 MPG.
Spreadsheet with all data is attached below.
That is 44% gain in gas efficiency! Sasha and I are both shocked. We didn't think Dan was going to see any improvements at all. Most people we discussed thought it was snake oil.
However, there is one more test we need to perform before we could say that this test is conclusive. See next section.
What could we have done better?
Sasha pointed out that maybe the pump is inconsistent. Although we'd hate to think gas stations are charging us based on inaccurate and imprecise pump, it is possible. In order for this test to be conclusive, we have to test the same gas pump. We'd here to perform the same two round trip test, with the same gas pump, with the oxy hydrogen unit off or both trips.
We'd like to perform the test on a longer route; a route that would use up at least a full gallon per round trip.
Dan is content with the MPG test. He wants to save gas and save the planet. I, on the other hard, also want to know how much HP/torque we gain or lost. I have a G-Tech Pro Competition (Road Race Version) that could be used to help us gather that data. It’s unlikely that Dan would allow us to “dyno” pulls with his vehicle. I wouldn’t mind trying in on my 2001 Subaru Impreza 2.5 RS. Unfortunately, it has a 2.5 liter engine, which required a bigger kit. All of Sasha’s cars also have 2.5 liter engines and bigger.
How would the oxy hydrogen kit work with a turbo? I’d like to test it with my wife’s 2004 Subaru Impreza WRX STi. But again, the STi also has a 2.5 liter engine.

Hello i was reading about the unit online so i'm trying to do my research before i go any further. but based on your test, would you recommend it? thanks i would really appreciate your imput on this. i also live in the LA area.
Hold off on buying it... We're in the process of more thorough tests. They'll be posted soon, but they don't look nearly as encouraging as the first test.
Check back soon for more results.
did you performed your dino test?, i'm realy intreted by the result. I just by an AL-12 for my Honda civic TYPE R (european SI 225HP)
The Pump Test
Well, I couldn't wait any longer. Convincing Dan to do the pump test is harder than [fill in the blank here]. So I decided to do it myself, with my own car . . . the 2001 Subaru Impreza 2.5 RS.
I would do the loop twice in my car, without oxy hydrogen in either case. This test is to prove or disprove whether the pump is a precise instrument for our test.
At 12:40 AM, I pull up to the same Valero gas station we used before. I even pulled up to the same pump. I filled the car up and went on the drive.
The loop was exactly 21.5 miles. My car's odometer showed the exact same distance as Dan's car. The first fill up is 0.845 gallon. So far so good. Seems consistent with our earlier results.
I did the second run, coming in again at 21.5 miles. The second fill up is . . . 2.014 gallons! What the F**K!? Same exact distance, but the difference was over 1 gallon!
At this point it is obvious that the gas pump isn't a precise instrument that we could use for this test. The results we posted earlier should be thrown away. My receipts are attached below. No one else had used the pump between my three fill ups, which you can see in the even SEQ NUM.
To provide full disclosure, my car has a worn clutch. However, I have tried to modulate the throttle as consistently as possible without slipping the clutch. We can't think how even with a slightly slipping clutch, the result could be off by more than one gallon. We can only think that the gas pump isn't a precise instrument.
These are interesting results, one of my neighbours is using one of these, I'm interested but want to know more about it before proceeding (I'm an engineer).
I'd have thought that petrol pumps have to be calibrated to a certain degree, otherwise the petrol stations could advertise cheap fuel then over meter what they deliver.
It'll be interesting to see further test results.
Do we know whether savefuel.ca has conducted safety tests with this highly explosive gas?
"Oxy-Hydrogen gas is easy to make. Of course this gas is too dangerous to be of any practical use, but who wants to be practical ALL of the time? Please note that this gas is OXY-Hydrogen, and not pure hydrogen. Pure hydrogen can be stored safely, but Oxy-Hydrogen is HIGHLY EXPLOSIVE and CANNOT BE STORED SAFELY under any circumstances!! Don't try to store it!! In the above diagram, water is decomposed into its constituent elements, hydrogen and oxygen through a process known as electrolysis."
Dan now has the oxy hydrogen and all parts in hand. In this talk show, the RTS crew decides how they are going to mount the device in Dan's car. 6:05 minutes.

what are the standard methods or procedure to measure the fuel efficiency(petrol consumption in gallons per mile traveled) for apetrol driven car to check up againest the claim of automobile company in their advertisement.
your last video was a waste of 5 minutes and 13 seconds.
WTF once again, this is bullpucky.
Does the lye additive work better than the baking soda? If so, where can lye be purchased?
There are not "many companies" selling these worthless devices: there are a very few such companies, selling the devices under a great many names. The most popular is the one sold by the convicted felon Dennis Lee.
None of these devices work. The "test" mentioned above is, of course, utterly worthless for testing a vehicle's miles-per-gallon: driving behavior changes fuel economy drastically; one also needs to drive many hundreds of miles, double-blind (not knowing if the device is on or off), several times, for a valid test.
The James Randi Educational Foundation has a one million dollar prize for the first person to show up with an automobile with one of these devices installed that show a marked increase in MPG.
You did not get a 44% increase in MPG: you did not test the device properly. When properly tested, the devices show no increase in MPG.
You were ripped off; you were robbed, swindled, stolen from. Be angry.
I scanned the post and one thing came to mine. Your initial report was good as expected. Then the mpg began to fall off and actually worsen..also expected.
You cannot blame the pump for the discreancies. From looking at the design of the AL-12, it produces 12 liters per hour. That translates into 0.2 liters per minute. That small amount would hardly have an impact on efficiency of combustion.
Next thing I noticed is that your vehicle is OBD-II compliant. That means your car monitors the O2 in the air to fuel mix of the exhaust. When the O2 sensor reports a lean condition the ECU adds more fuel to compensate and tries to keep the exhaust at a 14:1 air to fuel ratio.
Bottom line is no matter how efficient your oxy hydrogen generator is, the ECU would override the performance due to the lean report from the O2 sensor. The O2 sensors cannot distinguish between air and O2. So, if mpgs worsened, it means the car did what the ECU ordered it to do. Our cars are designed to be only 12-22% efficient in combustion.
Oxy Hydrogen generators work best in pre-1996 gasoline engines and in all diesel engines.
