I run Mobil 1 15/50 yr round here in Montana. The difference in
"flowability" between the Mobil 1 15/50 and the Delo 400 15/40 I run in my
diesel truck at 10 deg or less is pretty significant. I tried using Mobil 1
10w30 and lost about 1 bar on oil pressure across the board so switched back
to 15w50.
