A gift for HHO Skeptics!

I've done fuel economy tests on a 1998 Jeep Cherokee sport that showed a 10-20% increase in fuel economy with the HHO system on. If it's not the HHO, I would truly like to know why it works. I'll be doing more tests on my ford focus so hopefully I can figure out where the 10-20% gain in fuel economy comes from. I'd just like to know where the extra fuel economy comes from.

Did you do any sort of tuneup on this Jeep?

well i guess i will just use my stainless fender washers to bolt on my aeronose then

HydroJim, so everything being the same, you can flip the switch off and your mileage drops 10-20% and you can show this with an instant MPG read out while you have cruise control on or are otherwise on a flat road maintaining the same speed?

These were direct before and after tests that I did multiple occasions. Nothing else on the vehicle changed and I went to the same exact pump at the same exact gas station and did the tests when traffic was low to insure accuracy. At the time I didn't have any instrumentation hooked up to the vehicle except for the onboard mpg computer which always showed a higher MPG than normal with the HHO but I ignored that because the computer always over reported the mileage with or without HHO. I did fuel economy tests by filling up the gas tank all the way to the lid and measuring the amount used and recorded the miles traveled. I admit the sample sizes were small(30 miles at a time) and once I find the time to get the system on my focus up and running I will be running longer tests with an ultragauge hooked up and I will try turning the system on will running down the highway and see if the mpg changes instantly. I'll definitely post my findings. I'm just trying to find an explanation.

Meaning you could easily be led astray by filling errors.
Even a small error in the recorded miles or fuel volume is going to have huge effects.

Sample size were small. Ridiculously small.
Not a good way to measure fuel economy.
Even if the fuel was supplied from a portable fuel container, either incrementally marked or placed on a accurate weigh scale, 30 miles is just not enough run time to get effective comparable results with.
Just using the cars gas tank and the auto shut off at the gas station after 300 miles let along 30 miles would be inconclusive. The longer the sample mileage the more complete of a result you will get.

The cars gas tank should be filled from the same pump, parked in the same position and filled to a point on the filler hoses neck where you can see the settled non foamy gas's level, repeat on subsequent fill ups.
Not trying to be Dic to you HydroJim, its how i measure my cars economy because its the only way to accurately measure at fill ups, short of supplying the gas to the car from a Jerry can.

The good old Commonwealth of Virginia passed a law that requires any HHO installation to pass the same emissions standards as the vehicle did when new. Try that with one of those vehicles that you "fool" into running leaner than it was designed to do, which makes the NOX emissions skyrocket.

Big fine if you do the installation and do not get it tested and not worth it when you get no better mileage.

I have $1000 for anyone who can make my Fiesta get 20% better mileage with a HHO installation that passes the same emissions test the car did when new. It's a 2011 model that has averaged just under 46 MPG for the last 4k plus miles.

Bring it on. We can both lay our 1 grand on the table and if you fail I keep your cash. If you succeed then you can keep my cash. You need to get the Fiesta up to 55 MPG.

Ho ho ho guys, put your money where your mouth is, your credibility is in the toilet and that's the only way you'll climb out. That, or admitting your massive **** up.
