Today’s cars generally have internal combustion engines (ICE). Combustion occurs in the cylinders that are inside your engine. The way engines work is an extremely complex story. In short, the fuel injector injects gasoline under great pressure into the cylinders. In essence, the fuel injector is valve that leaks a certain amount of fuel in the motors of vehicles. Fuel injection atomizes the fuel due to a tiny squirt under high pressure. A controlled explosion then occurs in the cylinders, which is used to propel the vehicle. However, over time, this process creates impurities. This grime creates more problems.The first and most important is that it reduces the power of the engine. Another, even bigger problem is the reduced fuel economy. The third problem of a dirty fuel injector is releasing harmful gases. To prevent such a problem, it is necessary to clean the fuel injector. Therefore becomes a very important answer to the question: How to choose best fuel injector cleaners ?

How do I know that my fuel injectors need cleaning?

The best sign is that your engine does not react in the right way after pressing the gas pedal. Also, if you feel that your engine no longer has the same strength as before, you should also clean the fuel injector.

There are also a number of other minor symptoms which indicate that your fuel injector is dirty: poor idle, hot / cold starting issues, engine knock or detonation, deceased acceleration, and increased fuel consumption all may refer you to a possible cause.

How often should I clean the fuel injector?

The answer to this question depends on many factors. It would be best to clean it every 15,000 to 20,000 miles traveled. If you drive an older car, it should be cleaned more frequently, for every 10,000 miles traveled. The car engines that use fuel with lower octane grades are very susceptible to soiling. For example, a vehicle in which the owners pour 87 octane fuel will likely accumulate dirt into the engine.

Why you should use fuel injector cleaners?

The first and most important reason is because of the ease of use. There is no need to drive the car to the garage to take apart and clean the engine parts. Another reason is the much lower price of cleaning. Usage of injector cleaners is simple: you just need to add this liquid to the fuel. Sometimes this process must be repeated several times. In any case, you do not have to pay money for repair and you don’t need to have a lot of technical knowledge for this.

You’re probably wondering, what does fuel injector cleaner consist of? The answer is simple: it is a mixture of detergents that effectively break down and clean all deposits that accumulate in the engine. Your entire job will be to pour the contents into the tank and continue to drive your car.
