Over time, the fuel injectors in a car's engine can become clogged with dirt, debris, and other contaminants that can impair their ability to deliver fuel to the engine efficiently. This can result in a variety of problems, including reduced engine performance, decreased fuel efficiency, rough idling, and difficulty starting the engine.

A fuel injection cleaning service is a process that involves using a special cleaning solution to remove any deposits and contaminants that may have built up inside the fuel injectors. This can help to restore the injectors to their proper functioning and improve engine performance and fuel efficiency.

Typically, car manufacturers recommend getting a fuel injection cleaning service performed every 30,000 to 50,000 miles, although this can vary depending on the specific make and model of the car, as well as driving conditions and other factors. If you're experiencing any of the symptoms mentioned above, it may be time to schedule a fuel injection cleaning service for your car.
