What C9 said... I ran my 427 last night for 30 minutes parked in my 55 degree garage. The water temp was at 175 and the oil temp barely broke 150. If I had been out on the road with wind passing over the oil cooler and Aviaid pan the oil wouldn't have gotten to 140...

I liken this to "el nino"... Several years ago the US depolyed deep water sensors in the pacific ocean, shortly after that we began sensing surface tempature by satellite...

Suddenly climate change became an issue. There were "strange" changes in ocean tempeatures never before recorded. The truth is they have always happened, we just haven't been able to record it.

My oil temp seldom goes over 165 on a hot day in California, say 110 outside. Obviously if your sensor was someplace in the center of the oil unaffected by exterior temp. changes it would be more accurate but we live in the real world.
