Am just enquiring as to what my "normal" operating oil temp should be.

at the moment when running around town or on the highway it reads 210 degrees F.

I have one of these block adaptors so the sensor is right where the oil filter goes...

Is this a normal reading?

 

Typically oil temp should be about 15* more than the water temp in the pan.Its hard to compare temps anywhere else in the system.At about 300* most oils rapidly loose their lubricating qualities.

hmm in that case it would seem a bit hot as my water sits at around 185ish...
but oil in the pan would be a tad cooler then where I am getting my reading from I would guess..
