This product works very well, Royal Purple Synthetic.

Posting mostly as a rant, so I will allow the business to remain nameless. I’m following this thread as I am putting my differential back in my ‘72 this week.
Earlier today, I went to the local auto parts store to buy the lube. I couldn’t find the additive so I asked someone. That someone had no idea what a positraction additive was. So I started to explain, only to learn he did not know what positraction is. When I started to explain that, I noticed his badge said he was the manager. I said “wait, you’re the manager of an auto parts store and you don’t know what positraction is?”. Nope. I put the rest of my stuff back on the shelf and went to a different store.
