How much MPG can I add with HHO technology?
http://www.gassaverguide.info/hho.html

i have put hho on on a chevy truck, it went from 14mpg to 19mpg, a jeep wrangler V6 it went from 17mpg to 24, and a VW Jetta Diesel, it went from 47mpg to 64mpg, amazing gain with the diesel. thats just an example of what hho can do for a V8 V6 and turbo diesel. good luck, and by the way i made all of my own kits with plans off of youtube. Dont buy those kits off of the net, they are a scam, they dont make enough hho, a home made kit will out preform any net kit, and home made is like 1/3 the price of the net kits. good luck and do alot of research before you do anything to your vehicle.

None as it is a scam.. I am 77 and heard this all my life and never have I saw one work yet.
