I change the oil in my 2014 Fusion with the 2.5 spring and fall. I don't get many miles on it but it gets LOTS of short trips, so change it often. In my stash I have 5/20 and 0/30 M1 and 5/20 motorcraft oils. Which would be the preferred oil to put in now for summers use? I am thinking the 0/30, but maybe I am all wet.
