This stuff costs nearly $2 per OUNCE to add to your tank.
I'm going to start selling gasoline under the name brand 'tank extender' in 14oz bottles for $1.40 each ( 10 cents an oz ) and tell people I will guarantee it will add 10% to their MPG if they add just 14 ounces per gallon.
Betcha it's gonna sell well!
P.S. It won't be fraud. It will work, and best of all, it will be perfectly legal!
