Pattern Altitude
My M20C is running hot, Not redline, but close to it. The pressure is normal. This during cruise, not just climb. It is the Lycoming 180HP. I tried adding oil, bringing it up to 6.5 quarts, with no change. The outside temp has been close to 90s in AZ, and 80s in altitude. This hasn't been an issue until the temp has started to rise. when its cold outside, she runs cooler. Wonder if anyone else has had this problem and what did you do?
