75W85 viscosity gear oil

[DTNS]

what is the correct ratio to get this viscosity of gear oil?

I've read some forums and resources say that its 25% 70W80 + 75% 75W90, while others say its 50:50 of 70W80 and 75W90.

which is it really?

Follow manufacturer recommendation. If it is for the Evo, IIRC, the Gear300 75w90 of MOTUL is recommended as it has the special additive for protection of the gears.

if it requires that viscosity just get the 75w90. the extra thickness won't really hurt performance naman since the difference is so minimal.
