Most dedicated 75W90 MTF's have a 100C viscosity of about 14.5 cSt.

This stuff has a 100C viscosity of 19 cSt. Good luck shifting in the winter.
I’ll just cut it with a quart of synchromesh :)

Owners manual specs 75w-90 multipurpose gear oil. What’s the viscosity of the typical gear oil in this range?
