Winter oil

[Ranhil]

I am sure this has been answered before, but I could not find anything in the archives. What oil is the best to run in a 4030 diesel in a very cold climate? thanks in advance.

Here in the midwest we use 15/40 year around.

15/40 year round. Use block heater two hours before startup.

I sure like the Deere Plus 50 series of synthetics. Increased sump time, and their 0W-40 is good to -40°.
