Anyone used Nulon full synthetic 75w-90?

Am going to change my gear box oil in the next weekend or so (sti 6 speed) and wanting to put either Motul 75w-90 or Nulon 75w-90. Found that the Nulon is easier to source and just wanting to know if anyone has used it and any feedback on it before I go and spend $100ish on it, Thanks.

6 speed need and MUST run a special gear oil !

because there is an internal oil pump in the box the gear oil must also be rated for the pump aswell as the gear set

I thought the manual says 75w-90? What would you recommend using?

Not all 75w90 are made equal

Motul do a good oil for 6MT but its not cheap at $30+ odd per litre

I'm using their synthetic GL4 fluid in my Skyline's 6-speed box, definite improvement over whatever crap fluid was in the before. I had a hard shift from 1st to 2nd, not crunchy but had to use force, that is gone now.

Done about 3000kms on the street and about 60 laps of Pukekohe with no issues.
