What I've heard is that EP additives used in gear oils don't get along well
with with older-style overdrives. Kinda makes sense to me, as EP additives
do some chemical hocus-pocus that effectively sacrifices a miniscule layer
of metal on the gears for the greater good of extreme pressure reliability.
Must be something in the OD's that doesn't take this slight loss well.
