If you've ever wondered whether fuel injector cleaner can clog fuel injectors, the answer is yes. Fuel injector cleaner is designed to clean the injectors, but it can also clog them if it's not used properly.
Here's how it works: when you use fuel injector cleaner, it breaks down the deposits that have built up on the injectors. But if you don't use enough cleaner, or if you don't let the cleaner soak long enough, the deposits can re-form and clog the injectors.
To avoid this, make sure you use enough cleaner and let it soak for the recommended time. You should also be sure to follow the directions on the bottle. If you're not sure, ask a professional.
With that said, fuel injector cleaner is a valuable tool for keeping your injectors clean. Just be sure to use it properly.
