I've been changing liuky moly molygen 5/30 for six months now, everything was fine before that, the last replacement apparently went fake oil because I drove 3000 km the oil was not normal, I went to the service to change the oil, they do not pay attention here, too, do not buy anything because they already sell diy oils, I do not advise. I have a car of 10,000 km, I drove the last 3,000 km without problems, I came to have no oil, I have now changed another engine and everything is fine, I have all the proof, the receipt is all there
