Review on Semi-synthetic engine oil IDEMITSU 5W-40 SN/CF, 200 l, 199.6 kg by Jnis Dvids Tts ᠌

I decided to check what I was driving and what was happening with the engine, I sent my Idemitsu 5w40 oil for analysis, which I bought at a share of 1700 for 5 liters. After 5400 km. mileage was greatly liquefied, although there were still norms for additives. I sawed the filter and there was cast-iron dust where the iodine magnet stood, I always saw the filters after changing the oil and this did not happen after MANNOL, CASTROL, LUKOIL, IDEMITSU ZEPRO. There is a video about the analysis of my fresh oil and testing on YouTube, so I can confirm who does not believe. My opinion is that this oil is not needed, even for free.
