[TenTec] What's the current consensus on PTO grease?

[Stuart Rohre]

Al, thanks for catching that grade of Dow grease question.  I only had 
one grade, and have not had a chance to evaluate the 44 Light.
I am sorry, that is right, there were different grades, and what we had 
in the lab was 44 Medium.  We have used it extensively on packing 
precision bearings in other higher speed instruments, for its thermal 
properties.
As a wide range operating temperature grease, it does not work out of 
bearings, and it does not harden over time.  It exceeds what the natural 
petroleum grease can do in that regard.
