How to clean your fuel system with 4-Power G
Add 4-Power G when filling the fuel tank. First-time users should add 4-Power G to two consecutive tanks of fuel. After the second tank, if the vehicle is equipped with a fuel filter, it should be changed. Then, treat one tank of fuel with 4-Power G every 4,000 miles or four months. Boost mileage even more by adding Conklin Fuel Mate Plus® Fuel Conditioner at every fill.
