Can you use non-sytn straight 90wt gear oil in land rover disco 1 diffs? or could there be adverse affects?

I use 90W in both diffs and the t case.

Yes you can and if you want to use a great oil try this GL6 rated oil for Superior Axle.

I use 90wt as well no problems and with a locker.

Disco I diffs are in essence no different than Series Rover diffs. They've been using dino based gear oil since '48.

90wt is the stuff. Use it and prosper.
