MPG-Caps are pills (developed by FFI that you place into your gas tank when you fill up at the gas station. These pills once dissolved into your gas (takes about an hour) and ran through your system give you:
Better Gas Mileage
Increased Performance=More Horsepower (HP)
Lower emissions levels
For some cars it takes up to the third tank of using these pills to see results.
Increases in mileage range from 7-14%.
Each pill costs about $2 but saves you up to $10 (and more as gas prices go up!) filling up each tank(depending on size of gas tank, increase in efficiency and price of gas).
