[TenTec] Solving PTO drift

[Paul Christensen]

Mike and all...

I've been looking for a synthetic PTO grease, but everything I've tried is 
too "sticky."  What I would like is a synthetic equivalent to the viscosity 
of Lubriplate 105.  I've been using Lubriplate on my early HRO and Collins 
equipment, but I suspect the right synthetic grease will last longer.

Paul, W9AC
