The main argument against HHO is the assumption that the engine uses the HHO instead of fuel to run. The onboard generators add the HHO to the fuel via the injectors to enhance the burning of the fuel. All the fuel that goes out as heat and unburned emissions is the % of unused energy. When combined with the HHO, the fuel burns almost at 100% with little or no emissions.
Sorry, Big Guy, but if the hydrocarbon fuel injected burned with only 99% efficiency, the vehicle would be a VERY effective smokescreen generator. The POSSIBLE improvement here is a fractional percentage, not even measureable without seriously accurate equipment and very careful technique.
But man, the placebo effect can be huge.

My engine is running cooler right now. A full marker on the temp gauge. Wish I had a ScanGauge to tell you exactly what the temperature is running at. I noticed a definite difference in power. At this point no mileage increase. That usually takes a while because the HHO attacks the unburned carbon deposits and cleans them out of the system also.
If true, this would suggest LOWER efficiency, not higher. A cooler running engine will result in an INCREASE in fuel consumption. Ask anyone who has ever replaced a failed-open thermostat.
As for the cleaned out carbon deposits business, that would be a function of the small amount of water the HHO system would deliver as part of the gasses it passed to the intake, not a function of any hydrogen or oxygen.

If, in fact, if any measurable improvement in mileage is possible, it would be due to the inevitable small water droplets carried over into the intake, not to any hydrogen or oxygen. While it is true that the ENGINE running cooler results in lower mileage, a lowering of the peak combustion temperature
(but ONLY the peak temperature, and only if it is a SLIGHT lowering) will improve performance slightly. The upshot of all this is that the electrolysis of water is completely unnecessary. All that is needed to get the small improvement these systems sometimes show is the injection of a tiny amount of water. And the reason it isn't done is that the improvement is tiny relative to the costs and pain-in-the-butt factor.
