How to choose

Injector cleaner is an aggressive chemical cocktail that corrodes and dissolves deposits on parts. When cleaned, they can adversely affect polymer and rubber injector seals, leading to rapid wear of these parts. Therefore, it is important to follow the instructions given by the manufacturer on the container with the composition. Quality injector cleaner almost completely burns and removes contaminants from the fuel system. The truest test for the effectiveness of the composition is the improvement of the engine operation, the increase in its power after using the cleaner.

For diesel, the injector cleaner should be special, because diesel fuel has a different viscosity, respectively, and the viscosity of the cleaner should be different. When buying the cleaner, be sure to tell what type of engine you have and preferably name the car brand. This will help you choose the right injector and injector cleaner for your diesel engine more accurately.

After all the cleaning and maintenance work on your injector, it is recommended that you change your fuel filter. This will dramatically improve the quality of the fuel mixture going into the injector and reduce injector fouling. After flushing and cleaning your injector the test may show high toxicity of exhaust gases - it is normal, parameters will normalize soon.
