Hello everyone, various threads across the manufacturers deal with the topic of coking and their (often expensive) consequences for direct injections such as (T)FSI gasoline engines. A workshop employee recently pointed out to me Nclean and Ncoat/Ncoat.one, the German company Norrol, who won an industrial award, an inner oil additive, which according to his own statement is “the problem solver No.1 for coking and impurities in engines (burning room, turbo, oil cycle). The product is not a classic oil additive, the products work within the oil cycle. Nanotech, among other things, from modified silicon oxide (SiO2), aluminium oxide (AI2O3) and plasma treated graphite (C) would ‘enrich’ the surfaces. Is there any experience, does anyone know that or does anyone use it? Info links:http://www.ncoat.one/http://norrol.eu/http://www.2000km.net/2016/08/24/oldtimer-fahrer-better-with-ncoat-one/
