But note that Redline makes different oils for gearbox and differential.
Good stuff, no doubt, but I follow their recommendation NOT to use MT-90 (or
MTL) in differentials.

(Actually, I use Valvoline Synpower in my diffs. GL5 for better protection,
and none of the additive that can damage yellow metal.  And it's half the
price of Redline.  And I can buy it at some Autozone, O'Reillys, Pep Boys
etc.)
