Yes, we do.  You will receive an operational manual and downloadable link upon purchase for latest version of the manual.  This cuts down on environmental, administrative and paper costs. We also support your questions after the sale.  Our instructions provide basic, easy to understand directions as well as more detailed and technical information for those interested.

 No. Using KOH or NaOH as electrolyte, the freezing point will be between -12 to -30C and beyond, depending on the mixture.  Our manual describes what freezing point will be achieved.

The H2-Flex is a high technology device with metal alloy filter that keeps 100% of the water and steam in, only pure hydrogen can pass through. And because there is no oxygen, it does not need a bubbler or flashback like HHO gas and the dry cell types do.

The H2-Flex uses chemical reaction between water and aluminum to produce hydrogen gas on demand. Its small internal battery controls the automatic functions, such as detecting when the engine needs gas. It also provides safety shut down in the event that too much gas is being produced.

NO! You should never put water into your vehicle’s fuel tank!

No. The H2-Flex is based on chemical reaction and does not use electrolysis, and therefore, no electrodes.

Yes if you want to drive solely on hydrogen gas. But adding a little H2  gas to your engine will still improve efficiency. Typically adding just a half liter/minute will benefit you greatly, as long as you have some kind of oil or petrol in your fuel tank.

Yes, In fact, you must replace your aluminum pack after about 300 miles of driving on H2 alone. The H2-Flex will let you know when to replace your aluminum pack and when to add water.

Yes. Any type of water will be fine, this include very dirty water, seawater, wastewater, drinks, pee, etc.

Yes. You should, however, place the aluminum can in a sealed membrane for easy clean up.

We will buy them back!

No, Engine manufactures cannot discriminate against the use of a fuel additive. Under the terms of the Magnuson-Moss Warranty act, engine manufacturers must take the position that the use of a fuel additive does NOT void the engine warranty unless it can be proven that the specific additive was the cause of the failure. Manufactures may assert that the use of certain additives may prove useful.

No, you can connect the tube to the vehicle’s fuel line with a tee, so your fuel system remains the same.

 H2-Flex is based on chemical reaction between water and aluminum to make hydrogen gas, and no oxygen is produced. Therefore, no external power is required. HHO gas is 2-part hydrogen and 1-part oxygen, which is created from water or other liquid through electrolysis process. So external power is required.

The H2-Flex allows you to use the lowest octane fuel, even French

fry oil in a gasoline engine, without causing pings or lower engine performance.

Most computers in today’s cars and trucks show an average of savings and can be calculated in a number of different ways. It is advised, before using H2-Flex, to get a true MPG base line, by dividing the number of miles traveled by the gallons of fuel used. Then, once the H2-Flex is turned on, revaluate the savings by the same method. If you pull a boat or trailer you may have to remove the positive battery connection to reset the computer to get an accurate reading on your instrument panel.

The H2-Flex can be used on hybrid vehicles as long as it has an internal combustion engine (ICE). With our new hydrogen battery system (“H2-Cell”), the H2-Flex can also be used on electric vehicles (EV) and fuel cell vehicles.

Every vehicle is different.  You will see anywhere from 50% to 300% increase in MPG. There are a lot of factors for the differences, such as:

• The weight of the vehicle
• The type and size of the engine, such as 4, 6, 8, and 12 cylinder
• How healthy the vehicle is prior to adding a hydrogen generator is also important.
