I'm not sure there is a real practical location in the first place without huge testing to find the hottest oil point. What I think is important, is finding a location that is fairly responsive, and allows you to get input of excessive temp increases, tracked real time against your water temp. That should be enough. Oil pan works if possible, and oil filter sandwich temp and tap might also. twocents

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
