It works. If the injector nozzles are clogged. It's good. With the adulteration that all gas stations do, it's a good idea to pour a bottle into the tank. I saw on YouTube some Arab guys doing a cleaning directly after the fuel filter on clogged diesel injectors and it cleaned them. With 500 ml

I added it to a 2010 Lexus IS 220D with 300,000 km in almost a full tank with 65 liters of diesel. It significantly reduced the rattling, increased the torque and acceleration of the car, and slightly reduced fuel consumption. Overall, it made the engine quieter and more economical. I have driven over 2000 km since then with the same favorable results. I am satisfied; the product is very good, and I will continue to use it every 3000 km

I did not expect to see a difference and it is worth mentioning that I did indeed notice smoother operation, with fewer vibrations and possibly reduced consumption, in combination with overall service.

Very good especially when you apply two layers of filling, apply it continuously three times and then use the x3 feeding system cleaner, it does the job, but not on the first application.
