I did hydrogen cleaning of the internal combustion engine.
The 2019 Polo sedan has started eating a lot of oil. There are no smudges. I didn't smoke, they said I would have to make an engine overhaul and cook at least 400 dollars. I stopped by these guys, made a diagnosis, said there was no special sense in the capital, it was expensive, which was far from a fact for a long time (the mileage was already over 400t.km), offered hydrogen purification of the entire system, engine, catalyst and more. The result was amazing. After 10,000 km, the oil was light at first, it became much more cheerful to go, it began to start at all from half a turn, and the oil consumption accordingly went completely. Even the consumption has decreased from 7.8 to 6.3. Let's see what happens next, while I'm satisfied.
