I wouldn't count on a fuel additive increasing economy. Drag, tires, ring and pinion gears, and the weight of your right foot are all factors that can dramatically affect fuel economy.
I would imagine the amount of fuel you will save per tank will be the exact same volume as the amount of additive you put in. (I.E. if you put in 32oz of additive, you will burn the additive instead of gas, and that's 32oz of gas you won't burn...)

While he may have gone about it a bit tougher than I would have... it does smell of 'snake oil'. If its too good to be true, it probably is. There is no magic bullet to increasing mileage on these trucks. What are you currently seeing for mpgs?

I forgot they sold weight loss suppliments as well as a miracle formula for increasing my gas mileage. Sorry for being a bit skeptical.

Besides, if it really worked, it'd never make it to retail. One of the major oil companies would buy the rights to the formula, and start selling it in their gasoline.
Trying stuff like this is dangerous...if it were to clog up your fuel injectors, foul up your O2 sensors, or mess up anything else, the huge repair costs would never be covered under warranty.
