I would say I used Royal Purple because it was on the shelf, and I tend to buy locally as much as possible. I have not had good luck shipping small quantities of fluids up here, especially in the winter.

I have heard good things about RP, but not specifically from Toyota owners. So far, so good. I imagine it is comparable to the Redline. It advertises that its components are kinder to soft metals (brass synchros) than garden variety 75/90, which is the selling point of Redline as I understand.

You're fine with 75/90 in the differentials.
