What oil is best?

Gad, I'll never forget the first time I changed diff oil. That is the nastiest stuff on the planet.

The extreme-pressure additives are what gives it that distinctive sulphur smell

That’s what I’ll say to my wife the next time she complains about my farts.

Same thing applies for the 2.0?

Any and all differentials. Period. 60,000 miles is usually the factory interval, whereas 30,000 miles is the 'nerd' interval. If you see heavy towing or track use, change it even more often.

Toyota replaced mine at 7500 while putting new gaskets on my diff due to the diff leak. Been fine since but it will be something I replace prob every 15-20k miles going forward. Seems like a lot but doing lots of pulls on it I’d rather spend a little here and there vs replacing parts.

Wouldn’t hurt to change it

Super easy to change the diff oil. Faster than an engine oil change. I replace mine every 5 events or so. I have used OEM, LiquiMoly, and now Motul.

@razorlab posted the official procedure for it, it's super easy to do.

I have an unopened bottle of this stuff in the northern side of the Twin Cities, MN. I don't want to sell it, nor do I want to ship it. But if you live in town nearby and want it (for free), let me know.
