What are the Benefits of a Fuel Injector Cleaner?

Your fuel injectors are a critical part of your engine, helping to deliver the exact amount of fuel to your engine to allow for fully optimal combustion. But eventually, the carbon deposits, dirt and debris settle inside the injectors, so that can cause the engine to run the wrong way. When fuel injectors become clogged, they cannot deliver the proper fuel flow to the engine, leading to several issues such as:

• Poor engine performance: Misfire can result due to clogged injectors, especially hesitation, stalling or rough idling can occur.
• Reduced fuel efficiency: Clogging of injectors also leads to the situation when the engine working harder leads to decreased miles per gallon (MPG).
• Engine misfires: If the injector fails to supply the right amount of fuel, it indicates a misfire, which gives the engine a not so smooth run.
• Higher emissions: Incomplete combustion increases the amount of harmful emissions if clogged injectors cause the engine to operate in a way that’s less than perfect.

A best fuel injector cleaner will dislodge carbon deposits, dissolve contaminants as they form, and keep contaminants from getting into the fuel injectors. Regular use of these cleaners will help you keep the fuel system clean and your engine running smoothly.
