If it's cold try running a winter front or a piece of cardboard to get the temps up. You could also try a new T-stat. My truck has always ran cold, and the two temps are much closer if my ECT is around 190.
I know, I was just talking about your low coolant temps. The sensor obvously isn't reading the correct oil temp. I would replace it.But that doesn't explain an 80 degree delta between the two... Unless it's just because the losses to ambient being its always max 32 degrees causes the cooler outlet to be that low...
