All the additives stuff is crap and just takes your hard-earned money. All you have to do is make sure that your fuel filter is up to date and that you buy quality gasoline or diesel at a high volume station. And avoid Joe's five and dime discount gas. No additive is going to help a worn out or faulty injector.
So you had a bad injector and a new injector and we're supposed to believe it cleaned it that quick. Even in this short video you could have time lapsed it to show it going from a bad pattern to a good pattern.
It really depends on how you are trying to clean the injectors. If you're just putting whatever in your tank than personally I don't believe that anything is going to clean a extremely dirty injector in 1 cycle the fuel system. If you're taking the injectors out or putting a cleaner directly into the fuel rail than it very possible for it to work that quickly. Honestly whatever cleaner you use to clean an injector directly into injector is most likely going to work 😂
It’s necessary to clean your injectors. It’s part of a tuneup when you itemize fuel that’s everything. It gives you a nice clean efficient burn that’s why doing your injectors every 30,000 miles is probably not a bad idea and the dump in the tank that other those other products it’s already in the gas.
