The frequency of administering fuel injector cleaner refers to the interval at which this maintenance product should be added to a vehicle’s fuel system. For example, some manufacturers suggest its introduction every 3,000 miles, while others recommend longer intervals, potentially up to 15,000 miles, based on driving conditions and fuel quality.
Regular introduction of these cleaning agents can contribute to optimal engine performance by removing deposits that accumulate on fuel injectors. This can lead to improved fuel efficiency, reduced emissions, and smoother engine operation. Historically, the use of such additives became more prevalent with the introduction of fuel injection systems, which are more sensitive to fuel contaminants than older carburetor-based systems.
