And I am sure uni will back me up.
I live in a far ,far away land where the eskimos, wild unilievers, wild hammeheads inhabit the land .
It aslo can get a little cold ,as in your piss freezes before it hits the ground .

The point is myself ,including others ALL run 15-40 year round so don't think you need lighter oil for colder weather .

hahahahaha

There is no need for anything other than a good 15w40 in a big cummins. Anyone who says different i challenge them to come up here and tell me different.
