I keep getting replies like I have done something drastic like going from conventional oil to synthetic or a lot thinner oil. I only went from 20W-50 to 15W-50, both fully synthetic. Why should I expect oil leaks. I didn't have any leaks with 20W-50 fully synthetic,why should I have any with 15W-50 fully synthetic? It is not that different. What am I missing.
