As a certified mechanic, with over 25 years of experience, I know the ins and outs of vehicles. I also know how easy it is (or isn't) to perform HHO conversions on cars, SUV's, minivans, trucks, big rigs, cargo vans, RV's... including the new "E85" vehicles.

Twelve years ago, when I first started experimenting with HHO technology to achieve better fuel economy, I simply took it for granted that getting 40 to 60 miles per gallon
(64 to 97 kilometers) was normal when a hydrogen (HHO) system was installed.

But today, pre-built "ready-to-install" HHO conversion kits sell for as much as $800.

(For the best pre-built "ready-to-install" HHO conversion kits...see below).

However, with all these "do-it-yourself " conversion guides available online that use hydrogen for fuel, I have to shed some light on what is and what is not possible:

First: It is not possible to run your vehicle completely on HHO (these vehicles are still
in test production and are very expensive). You will still need fuel (gas, diesel or E85).

However, with HHO (also called "Oxyhydrogen", or "Brown's gas") being fed into your engine's air intake, "along with" gas, diesel or E85, your vehicle will get more miles per gallon (or kilometers per liter).

And you will save money on fuel.

Average savings: $50 to $100 per month.

Second: You will get at least a 50% increase in fuel efficiency... if you use 1 of the 3 guides I recommend below.

Depending on your vehicle & engine size, your vehicle's increase in miles per gallon will vary accordingly.  (A 67% increase is the "average" using my #1 recommended guide).

Yet, with that said, I have read reports from the USA and Canada of 113% to 279.3% increases in miles per gallon. You'll still have to buy fuel each month, but your monthly fuel cost will likely be one third to one half of what it is right now.

Third: In my tests of HHO conversion guides recommended by non-mechanics, some "recommendations" actually damaged the engine and/or destroyed critical engine components, which was very expensive to fix and voided the vehicle warranty.

So, to protect your investment,

I personally tested 21 HHO conversion guides based on the following criteria:

• Works with all vehicles.
• Uses a mechanically sound design.
• WILL NOT damage the engine or void the vehicle warranty.
• Provides a major increase in fuel mileage.
• Inexpensive parts that are readily available.
• Very easy for a beginner to build and install.
• Produces cleaner emissions (which helps to protect our environment).
• Produces the maximum amount of HHO ("Oxyhydrogen" or "Brown's gas").
• Works with all new and used vehicles on the market today
  (including fuel or carb injection, E85, diesel...and all hybrids).
• Faster vehicle acceleration.
• More horsepower (stronger torque / engine power).
• Works in ALL temperature extremes.
• Eliminates engine "knock" or "ping".
• Can be easily installed or removed.
• Eliminates carbon deposits from unused fuel.
• Compatible with IRS requirements (so you will get your entitled tax rebates to
  pay for the conversion).
• You'll get full rights to build and distribute the kit for personal use or profit.

Below are my recommendations of the top 3 water + fuel (HHO) conversion
guides that I have personally tested...and met all of the above criteria.
