On Friday pm as I climbed out of Chino to 12.5 my oil temp topped at 220dF too. That was about 20dF higher than normal, likely because it was indeed a hot day. Since I was worried I might get to the fly-in before the field opened I idled along at about 50% power so the oil temp soon dropped below 190dF. However if it had remained at or below 220dF I would not have been concerned. Of course less is better, but with quality oil on ISA + 30 days I think cruise at 220dF is OK--especially if your engine is relatively new and still tight. Mine is a Performance TSIO-550 with only 100 hrs and I expect the oil temp to drop 10 -20 dF during the next 100 hrs, at least that is my experience with other new engines. My advise: fly more and worry less... paul
