| MPG. 12,000 miles is 545 gallons at 22MPG = $2198 @ 4.03/gal 12,000 miles is 454 gallons at 26.4MPG = $1832 @ 4.03/gal $366 savings over an average year. It would pay for itself in under a year IF it performs for you at their maximum advertised benefit. I really question how effective any manipulation in the fuel's chemistry can be on combustion efficiency. Atomization is an important factor but recalling the numbers I've seen in emission testing results, I'm not inclined to say that there is adequate room for improvement in the combusion process to yield such gains they advertise. The amount of hydrocarbons that are found in the exhaust are too low - this value represents how complete the combustion process was. Given how low the allowable figures are, I'm not inclined to say that there is room for a 20% increase in mileage by way of producing more complete combustion. FWIW, I've squeezed 30MPG out of my Z without the expense of additional hardware and have an idea that may allow me to improve that close to 40.
