Satisfied, there are not many fakes of this oil. So for now, I use it without fear. Different pros: Objectively good oil, from the positive: - the feeling that the noise of the engine has decreased, not at times, of course, but noticeably smoother and softer to the ear. The engine spins up feels easier. Before that, Ow40 Mobil 1 synthetics were used - the oil is excellent and there are no complaints about it, it cleans the engine perfectly and, unlike the pan, does not burn out. This oil also showed that it cleans perfectly when replacing the cylinder head gasket. No deposits or sludge are observed. I am very pleased with the oil, and in fact with other products of this brand used. Has some cons: There are no complaints about the oil itself, the volume of oil is needed 7 liters, you have to buy 2 to 4 liters)) (in liters a little more expensive) and each time a liter remains in which to pour the subsequent remaining oil.
