I changed my oil last week after driving for about 45 minutes, so it had reached operating temperature for a good while. The oil temp gauge read about 190 degree F. The ambient temperature was about 55 degree. When I got home, I drove the car up on ramps, and because I was in a hurry, I decided not to wait 30 minutes before draing the oil. What's a slight risk of getting scalded, right? Naturally, I dropped the drain plug in the drain pan, which is the cheap kind. I had to go fishing for the drain plug, and to my great surprise, the oil wasn't all that hot. I could easily stick my examination-gloved (!!!) hand in there for 10 seconds without burning myself. I don't think the oil was hotter than 160 degree or so. I'm not sure where the gauge gets its data, but I guess it's at the oil pressure switch. I wonder if the oil in the pan ever gets hot enough to boil off condesation.
