Good to know. 

        I think I’ll weight on trying the 60 weight oil until engine oil pressure or age indicate it. 

        I’ll stick with mobil 1 synthetic 15w 50 for now but I’m glad to hear the 40 weight serves folks well as I wonder how easy my current oil will be to get in the future.  Down south I struggled to find more then 30 weight in Walmarts as we traveled.
