Fuel injectors are very important parts of cars. They are injecting the fuel at specific rates and specific pressures. And they are very important technologies that increase the performance of the car.

Carbuıerators were the previous technologies which have lower performance and fuel saving. After the carburetors, the application o the fuel injectors is very common.

And if the cleaning o the fuel injectors does not take place accordingly, the performance of the car will drop. Because these parts of the cars are very intricate and required extra attention. There is a very narrow nozzle that fuel comes with very high pressure from that nozzle. And these nozzles are directing the fuel at high pressure.

How Can You Understand that Fuel Injectors are Dirty?

Actuıally, in specific periods, you need to apply the fuel injector cleaning on your car. And if you are not clean your fuel injector, your car will give some indications that your injectors need cleaning. Around the most common indications;

  • Increased fuel consumption: The fuel economy will decrease with the filthy fuel injectors. Because efficient combustion can not take place with the efficient form of fuel.
  • Anormal starts: While you are starting your engine, it will be very difficult to start it propertly. Because the fuel injectors are clogged and it I very hard to supply the required amount of fuel to the combustion chamber. So, a hard start takes place for most cars.
  • Poor engine performance: You will feel performance loss in your engine while you are trying to accelerate. Because, when you push the gas pedal, the fuel injectors can not provide the required amount of fuel at high pressure to your engine cylinders. So, the acceleration and the performance of your car drop.
  • Rough idling: This is another indication of the fuel injector filth. ın the idling of the engine, you will hear unusual sounds coming from the engine combustion chambers. The main reason for this problem is the uneven combustion of the fuel. Because the fuel supply is not as it’s supposed to be.
  • Pre-ignition problems: Pre-ignition take place because of the uneven supply of fuel in the combustion chambers. The ignition of the fuel takes place before the spark of the plug in the cylinders. This is because the pre-ignition takes place with insufficient fuel in the combustion cylinders.
  • Excessive emissions: Emissions we will also change if there is filth and dirt on the fuel injectors. This is another important problem that you can face. So, you need to take care of the emissions of general things.

If you have these problems and if you did not make your fuel injectors cleaned, you need to take care of the fuel injection cleaning.

There are generally two types of fuel injector cleaning methods;

Fuel Injection Testing

In the testing of your fuel injectors, you can use the multimeters. With the applications of the multimeters, testing the fuel injectors are very simple. But there are lots of services that you can test your fuel injectors. They will assess the performance oft he fuel injectors.

How to Clean?

We suggested different kinds of cleaners from And you can understand that you use these cleaners in different kinds of gasoline engines. And you can not use these cleaners in the diesel injectors. Because diesel injectors are much more complex structures and you need a profession to clean them.

After selecting a fuel injector cleaner from the list above, you need to follow these steps.

  • Pour the cleaner into the tank: You need to pour all the liquid into the fuel tank of the vehicle. So, it will mix with the fuel of your engine. And once the fuel is supplied to the fuel injectors, the cleaner will take all the dirt into the combustion chamber. And in the coımbustion chamber, all the dirt will turn into dust and exhaust gas. So, your injectors will be very clean.
  • Add full tank of gas: In general, the concentrations of these cleaners are adjusted according to the full tanks. If you add this cleaner to the half-full tank, you can not get enough performance from it. And also, it can be harmful to the system. So, it is very important to pour into the full tank.
  • Use the second bottle: After the tank is empty after the use, you can apply the second bottle of it. Because you probably did not apply the cleaner in specific periods before. So, the filth and dirt on the injectors can be very tough and high. And if you apply it a second time if you are using it the first time, you will probably have the ideal results.
  • Use it every 7000 miles: To get the ideal results and never face the same problems again, we recommend you use this cleaner every 7000 miles of the car.

So the general applications of the fuel injector cleaner bottles are very simple. You just need to pour them into your gas tank and you will feel the increase in the performance of your engine and car.
