[Mgs] 90w in Transmission?

[Stuart MacMillan]

At least you don't have an OD tranny, but it would probably work sort of
okay there too.  90w gear oil makes is harder to shift because the synchro
rings have a thicker, slipperier layer of oil between them and the cone on
the dog gear.  I think the ears on the rings will wear faster the harder you
have to shift 

At the risk of igniting flames, I've used Red Line MTL for over 13 years in
my '65 with OD, and for 5 years in my daughter's '71 GT, also with OD.
Great stuff. Shifting is quicker, OD works great, and you never have to
change it.

This is a fallacy.  Factory V8s have 90 gear oil as standard, mine was a
daily
driver parked outside for many years including periods of below freezing and
I
never had a problem, but I can't speak for the condition of anyone else's
gearbox.  As long as it *is* gear oil, and not *differential* oil it should
be
OK, don't junk it now just wait and see how you get on.

  ...  With the engine cold, even in the
  summer, the 90W will be too thick for the snycros to work properly...
