I have tried additives from 6 manufacturers, including those that are not directly available on the Slovak market due to carbonization of the engine and with this additive the results were noticeable after the first run on the tank. I have it listed as the best additive. The engine problems themselves disappeared after 2-3 months of use, this is to be expected, but the EGR valve fault also disappeared by using a combination of alternating tanks one with LIQUI MOLY - Engine System Cleaner and the other with PRO-TEC OXICAT always alternated with VIF Super Gasoline as a maintenance intermediate additive. Occasionally with 100-octane petrol and driving at higher revs 3000-3500. The consumption itself did not interest me, it was not the goal, but I have a subjective feeling that it was smaller, but not radically. In any case, the problems with the engine have disappeared, the engine running is smoother and more refined, I will continue in smaller quantities, occasionally I will add the fuel injector.
From the ones I've tried, it's TOP

Cleaning the fuel path + injectors, increasing the octane number + increasing the ignition reliability (engine start so called. "on drc") + reduction of consumption .

All in all it fulfills its purpose of regular maintenance of the fuel part of the car.
Really cleans the fuel system
Good price
Calming the engine
It's no big deal, it won't clean a very dirty fuel system.
