Soarer AO2B Diff Oil

[MrBish]

Afternoon all.

Got a JZZ30 Soarer (1JZ+R154) and I want to change gearbox and diff oil. Read several places that Redline MT90 is good stuff for the R154 but can find very little about the diff, AO2B on the vehicle plate in engine bay.
I'm almost sure the diff's not standard as the inside wheel skips on tight turns, so not sure if that changes what I should use?

Any help appreciated

It does sound like it has a 2 way diff fitted. That or a very easy locking torsion dff.

Just use a gear oil for LSD vehicles with a weight the same as the gearbox. Something like 75w90. I use the MT90 stuff in both the diff and gearbox.
