My local mechanic friend says something similar, and I'll paraphrase to the best of my abilities since I don't get all the terminology, that engines today are so tight and that the Ford 4.6 V8 I have probably does better on that thinner oil because of the tight bearing clearances run in those engines. He suggested a full synthetic for better heat distribution but not to change the oil weight. I run Royal Purple already (fully synthetic) so I guess I'll stick with the 5w20 on that.
Thanks.
