I have completed my first tank of gas using FFT Fuel Catalyst. My previous best tank before FFT was 42.66 mpg. Without changing my driving style and temps being pretty much the same, my mileage jumped to 45.28 mpg. The dosage level is 1oz/10 gallons. At $19.95 for 16 oz, this figures out to be $1.25/10 gallons. If I figured right I saved just short of $.37 for this tank after figuring in the cost of the additive. Not bad.

Oops, I knew I forgot something. I guess I was too excited about the good numbers. Here's the link to their homepage. http://www.futurefueltechnologies.com/default.htm I think he can explain it better than I can. Basically, it helps the fuel combust more efficiently.
