M1 15W50 is not hard to pour. Marshall used to challenge people to put a cup of M1 15W40 and a cup of conventional 15W40 in the freezer, let it chill down, and compare the pourability of the two. Then think about which one you want in your engine when it's 10 degrees outside. In my case it doesn't matter because 15W50 M1 has become unobtainium in this area. Wal-Mart stopped carrying it, and nobody else stocks it in any quantity. I've been using Chevron Delo for the past year or so; good oil and easy to find.
