Have any of you guys used a hydrogen generator to add HHO gas into your diesel? I understand it increases mileage a lot. If so any preference to a specific generator. Thanks Blackbart

 

don't spend money on the plans you can get them for free.
I have a few of pals who have tried it in gassers with no lasting results, it might be different for a diesel but I doubt it most folks who try it see an improvement for two or three tanks of fuel then they go back to normal
