Even on a day with OAT at 10 to 30F, the oil temp should rise to the green range after about 20 minutes of cruise. If the oil temp needle didn't move at all, the gauge could be bad, or the temp sender is bad, or there's a broken connection between the sender and the gauge. A 150 owner can tell you exactly where the temp sender is. Remove it from the engine and put it in a pot of boiling water. If the needle doesn't move into the green range, there's a problem.
