[6pack] Proper gearcase oil

[slowtoaccept at yahoo.com]

John Espisito of Quantum Mechanics says to use 30 wt non-detergent for my
J-type Laycock OD tranny so it will not froth and foam and that heavier gear
oils cause problems. I don't know what he recommends for non-OD trannys. Maybe
he says on his website. http://www.quantumechanics.com/

I have a copy of an old Standard Motor Company service manual (pre J type)
for
Laycock de Normanville overdrives.   It specifies 30 wt non-detergent oil. 
It
specifically says not to use extreme presuure gear oils as the
"centrifugal
effect of the planets may separate some of the additives of the
oil and cause
sludging."

That is definitive advice.

However, In my 6 I have
Redline MT90 in my A type and I get compliments on how
well it works.  I'm
not switching.
