[FC] manual tranny/transaxle gear oil specs...

[Merv and or Loretta]

Hi all!

No one from WCC or Corvanantics or the Castrol Syntec tech centre answered my
question about what Mack GO-H/S means.
I plugged it into google and the MOBIL site popped up with an article that
blew me away.

Gear oil with this designation is good for 500,000 mile drain intervals,
suitable for extremely high load applications, and does not corrode copper.

I think that Castrol Syntec 75W-90 Gear Oil will work for our Corvairs, eh?
