Do hho generator kits really increase gas mileage 25-45%?

HHO generators are capable of producing results in gas mileage increase. How great the results all depends on the vehicle, setup, and varying factors such as climate.

Unfortunately, newer vehicles typically require sensor modifications to prevent o2 sensors and MAF sensors from enrichening the fuel ratio. People with newer vehicles usually employ the use of an EFIE along with their generators.

Try not to look at whether or not a generator will promise good results. Look at what the generator actually does. How many Liters/min of HHO will the generator produce? How large is your engine? Judge how it will benefit from having x number of liters of HHO injected into its combustion.

I recommend building your own generator and trying it out. That way, you can work with it to provide the best volume of HHO/min and achieve the best results.
