Putting it in the tank will help clean the injectors and such a little, but it will break sediments loose in the tanke at the same time so you should replace your fuel filter after you use it. Use it the intake way and it works best. Also 500 miles before you change your oil run about a 1/3 of a can in your oil. It helps clean it out.
