Directions For Use:
Screw on the unique, no mess, flexible spout, provided with the bottle of ProTecta Fuel System Treatment and pour entire contents into fuel. For best results use when fuel tank indicator is at one quarter (1/4) full. After pouring in contents fill tank to full with gasoline. Do not refuel until the fuel tank indicator is back at one quarter (1/4) full. This allows the contents to work with one tank of fuel. We recommend using at least twice per year in each vehicle, or pour in fuel with each oil change for maximum results.
