Hey I wanted to get this back to the top of post list to see if anyone has tried it.
I've researched it on many different sites.

And there is some stuff about it on youtube. Just buy a book to show you how and supposidly, gauranties 40% mileage increase.
Also have seen just the opposite claiming its a scam.
I remember back in the day I bought into a system you used container of water that you added this special brown chemical it caused a reaction and it was tied into you intake system. It didn't really work.
