[TR] now lubrication recommendations

[Jim Muller]

I've been considering refreshing the oil in my Spitfire's OD-enabled 
gearbox.  It's a rebuilt unit I got from Quantumechanics a few years 
ago.  John Esposito recommended simply a non-detergent, single 
viscosity 30 weight.

As I recall, few of the tranny oil recommendations made to this list 
over the last several years have mentioned OD at all.  For example, 
Randall Y. has been a big advocate of Redline oils, if I remember 
right, but I don't recall if he has OD.  So recommendations like 
Terry's always make me wonder:

How do OD clutches work in the presence of high-performance oils, 
which is what I suppose these are?  No lube engineer, I, so I wonder 
how the clutches work in oil of any sort.  But specifically I wonder 
if these most of recommendations are meant for OD.  And of course, if 
so why does/did John E. recommend some simpler?
