Every car owner refueling at domestic gas stations may encounter low-quality fuel. the vehicle's fuel injector system to stop functioning The main cause of the malfunction is the appearance of deposits that will interfere with the normal operation of the injectors. To prevent this from happening, experts advise using various cleaning compounds.
The injector device, why it needs to be cleaned
As mentioned earlier, the injector uses nozzles to directly spray the fuel mixture.
Injectors are an element of the fuel supply system that injects it directly into the combustion chamber of the engine. Clean and serviceable injectors spray the fuel mixture in a cone like an ordinary deodorant.
The main characteristics of the injectors are the spray angle and the size of the micro droplets of the fuel mixture. The operation of the engine directly depends on these characteristics. With a large angle and minimal droplet size during spraying into the combustion chamber, the fuel mixture burns much faster than with a small angle with large droplets.
While the car engine is running, the injectors are directly exposed to high temperatures. As a result, with constant heating and contact with the fuel mixture, plaque forms directly at the place where the fuel is sprayed, called a nozzle. Moreover, the deposit formed on the injector nozzle consists of elements contained in the composition of the fuel itself. Substances that form deposits on the nozzle cannot be removed or filtered from the fuel. Over time, this deposit directly changes the spray angle of the fuel mixture and the size of its part. Which has an extremely negative effect on engine performance. In particularly advanced cases, the injector stops spraying the fuel mixture altogether; it is fed into the combustion chamber of the car engine as a stream.
As a consequence, this leads to the following problems:
- Fuel consumption increases significantly;
- Reduced engine performance;
- Problems starting the engine;
- Unstable engine operation at idle.
Today, there are two main ways to combat the problem of deposits on injectors, namely:
- Cleaning injectors from deposits using ultrasound. This cleaning method is extremely effective, but, unfortunately, it has two main disadvantages. The first of them is that only injectors are cleaned using ultrasound, and not all elements of the fuel supply system. The second disadvantage is the impossibility of using this method for nozzles that have ceramic elements in their design, since such nozzles become inoperative when exposed to ultrasound. This cleaning method can only be used in a specially equipped car service center.
- Flushing the fuel supply system. Flushing this system is again carried out in two different ways. The first of them is flushing the fuel mixture supply system in a specialized car service center, which costs a lot. It is carried out using special reagents, and there are advantages over ultrasonic cleaning techniques. Thus, when cleaning by flushing, there is no need to remove the injectors; flushing is carried out through the fuel rail of the fuel supply system. Also, when flushing with this method, you have to change the spark plugs. This method of washing the injector requires significant financial investment. The second way to flush the fuel supply system is to do it yourself using a special liquid.
Stages of pollution
You can respond to a clogged injector in a timely manner if you know what the stages of this process are:
- Small. It is very difficult to notice such contamination, since engine power drops only by 6-8% and this has practically no effect on its operation. Such pollution can only be seen by increased fuel consumption. However, it is also not recommended to flush the injector too often.
- Average. In this case, gasoline is consumed in large quantities, and the acceleration speed is significantly deteriorated. The performance of the injectors decreases by 14%, the engine begins to stall when idling, and the smell of smoke has a pungent, unpleasant odor.
- Critical. This degree of pollution is characterized by unstable operation of the engine, which begins to run jerkily. When you press the gas pedal, strong dull noises appear in the form of pops. Injector performance is reduced by 30−50%.
If one of the listed problems appears while driving the car, it means that the injector needs to be cleaned. It is better not to postpone this procedure and carry out it at the middle stage of contamination. If a critical stage occurs, there may be more serious consequences.
I bought Wynn's injector cleaner. I cleaned everything, the car flies. I am very glad. I have an old Mazda, I don’t know how the fluid will behave with new cars.

Cleaning methods
There are currently two cleaning options:
- using ultrasound;
- using a special liquid that can be found on the counter in any car store.
Cleaning using ultrasound involves the use of special equipment, with the help of which diagnostics are carried out, and only then the injectors are cleaned. This requires a visit to a specialized service station. The advantage is that a professional test is carried out behind the wheel of the injector cleaner on a bench.
The use of special liquids makes it possible to clean the injector without removing it from the engine. As a result, all existing contaminants are removed from the injector, valve walls, and other working surfaces. This is a more affordable alternative that you can do yourself at home. The result will be no worse, and you can test the injector cleaners yourself.
I read a lot of reviews before purchasing Hi-Gear Injector Cleaner. I was very worried whether everything would be okay with the new car if I washed the injectors. Everything is fine, the effect is gentle, I did not see any problems in further use.

Pro Tips
- Products poured into the car tank should only be used for prevention on new cars.
- If the injector is seriously dirty, you should contact a specialized salon, since liquids used for cleaning with your own hands are unable to properly clean heavy deposits. In addition, the use of such a liquid can completely aggravate the situation; if such products are used on a car that has never been cleaned the fuel supply system, deposits from the fuel tank can clog all elements along the fuel path.
- When flushing the fuel supply system with a special liquid, you should read its instructions very carefully and follow exactly as it says, otherwise there is a high probability of causing harm to the car.
- Preventative cleaning of the injector can significantly reduce the car owner’s costs in the future.
- To flush the injector, you should use only high-quality and proven products. Using a counterfeit or low-quality product to flush the fuel system will certainly negatively affect the operation of the car.
