Which grade Motor Oil?

What grade motor oil is best?
I believe we coverd this a week a go ...but ...I have a problem with #'s.

20 w 50 is what I believe I am looking for in a thicker OIL.

It would be fine in NY in the summer but I'd drop down to 10w-40 for the winter.

Thanks Joe
It's been a very hot summer here.

my J has been dropping oil pressure ,when warm, for awhile now with 10w-40.
