Kelly,

I would tend to agree, but according to information I received from other on this group, I was told that the common practice was to measure the coolant at its hottest point, and oil at it’s coolest point.  

 

It’s logical place to measure the coolant at its hottest point since that is its limiting value.  If you have coolant exceeding the boiling point anywhere (except for the nucleate boiling at internal surfaces) you have a problem. 

 

The limiting factor on the oil temp in the rotary is its ability to cool the rotors/seals, so it’s the temp at which it returns to the engine.  This limit is generally accepted to be about 220F, but could be exceeded some for short periods and probably not be a problem.  The limit on the oil itself (breakdown) is  higher; considerably higher for synthetics.

 

At least that’s my take on it.
