174 oil temp that's really cool but at 23 degrees OAT probably helps quite a bit. I run about 200 on a 40 degree day. I wonder though how one can cook the water (condensation) out of the oil if you run that cool.

The highest temp I've ever seen is around 195 in the summer and that's usually during the climb on the second flight of the day.
