[House Divided]

Returning from our trip West we ran through some pretty cold weather most of the way. Temperatures in the 20's and in the 30's if we were lucky.

Running down the highway with engine temps just under 200 degrees my oil pressure stayed above 65 psi most of the trip.

Now that we are in slightly warmer Alabama temperatures (50 degrees) I took a test drive - oil pressure stayed in the high fifties.

I am running Rotella T 15w40 motor oil.

I am wondering if oil pressures that high are normal in that cold of weather. 

I can imagine all that oil in the oil pan never gets too warm. Wish I had thought to take a temperature reading of the oil pan with the temp gun but I didn't.
