unhappy with 80w-90 gear oil

[Abletobecain]

Mid-winter update: I drove around in some low-to-mid-30s (*F) temperatures in the Tercel over the last few weeks. The Redline MT-90 still feels great with no grinding in any gear and smooth operation despite the cooler temps.

That's great news! I put MT-90 in my DD and not 30 miles later the water pump siezed and ripped my HB in half then a headbolt moved funny on the retorque and sheared off when I was attempting to replace it. It felt great for those 30 miles though!

So what's the community's choice for oil in the rear diff?

I'm running Ravenol 90 gl5. I got it cause it's an actual liter. Good stuff and pretty reasonably priced on Amazon.
