Review on Synthetic engine oil IDEMITSU 5W-30 SN, 4 l by Adam Kowalski ᠌

They advised me to buy this one, I was not mistaken in my choice. Confuses the lack of inscriptions on the bottle about the standards themselves API, ACEA, ILSAC. Before that, I used GM oils, Totachi, I hope this oil will show itself no worse than Totachi and better than GM. After changing the oil, the engine ran smoother and smoother, the lack of standards on the bottle confused not only me, but also in the car service, let's see how it behaves to increase mileage.
