I rented a 22 Toyota Sienna Hybrid 27-30mpg at 70mph, I installed two set of magnets (two separated fuel systems - direct and port), treated motor and Tribo-Max Fuel +. I drove almost 2500 mile one way with 1400 lbs of load weight getting 33-35mpg but now coming back with no load it jump to almost 60mpg. A big shout out to Sienna Hybrid owners and it score 92% effective. I wasn't expecting these kinds of results. Like my old friend Danny use to say you never know until you don't try.
