I have used Fuel Treatment at every fill-up
Have a F-150 purchased with 35,000 today I have 250,000 and have used Fuel Treatment at every fill-up have only needed to change plugs two times no problems with fuel injectors, actually I have had no problems with any part from the fuel pump to the exhaust system. I still pull my 16 ft. fishing boat to reservoirs far and near. I also still drive to my daughter’s house 2,000 miles every year. It’s my daily driver.
