Ok I knew there was something to the color.

 

Hydrogen is pretty interesting stuff. I make it all the time with only a solar panel. Anyway, Exxon Mobil claims to have made their own onboard hydrogen generators for vehicles. Look it up, they even had tv commercials. I wonder if they realize the average Joe beat them to the punch. Although, I have not installed one myself, I know someone that did on a tahoe and said they increased their mileage by 30 percent. This guy actually owned oil and gas wells, very wealthy man just wanted to see if it worked.
I think a lot of it has to do with tricking the O2 sensors. Some people add extenders. I think you should focus on the particular vehicle and research how others have installed on vehicles like yours. Good luck, I will try it soon myself.

 

Pictures or it didn't happen. Anyone else notice how everyone knows "someone" that did but can't prove it? That's pretty convenient.

 

I agree. My uncle's next door neighbor's ex roommate's girlfriend's step dad's army buddy went to school with a guy that knew someone who did this.
