On average, using the 25% ratio, the end user will see some results, but not greatly increased miles per gallon results. Minimally, these are some of the noticeable benefits:

• Carbon and gunk buildup in the engine will disappear
• Improved fuel/air mixture
• improves emissions by lowering the carbon emissions of that engine
• slight increase in horsepower (5% to 10%)
• less wear and tear of the engine

If a larger cell is installed, 125% HHO production per 1 liiter of engine displacement and tuned properly, the end user can begin to significantly improve their miles per gallon or decrease fuel consumption; then the end user can expect on avg of 25% gain in mileage or a 25% reduction in fuel consumption.  If 200% HHO production per 1 liiter of engine displacement and tuned properly, the end user can expect up to a 50% mileage gain or 50% decrease in fuel consumption.

For most smaller automobiles with a 1.6-2.0 liter engine that the end user is desiring a 25% increase in their mileage we recommend a cell that produces minimum 2 LPM, but can produce up to 4 LPM.

For enterprise applications, for example a Tractor Trailer / Big Rig with an engine displacement of 885cu in. (14.5 Liter Displacement), we recommend using our TT series TT186 which requires 144-540 amps of current at 12-14 volts DC and produced 18-36 LPM of HHO. This obviously requires an alternator upgrade, since the majority of stock alternators are 250 amp, but the costs justifies the means and in terms of costs, $400-$500 for an alternator is nothing compared to the extensive fuel savings.

Whatever your engine displacement is, we have the right HHO Dry Cell for your needs.
