It's the same to-4 spec, I highly doubt it's cheaper

I just checked, the Irish 50 wt is $125. I checked around locally in January and the closest was $175, you will be shocked at the price.

I have found several times in life that name brand parts are less expensive.
In 1987 I had a catastrofic engine failure in an old International Harvestor farm tractor. At the time Central Tractor was the big other parts place. A used crankshaft was $1300. 1987 dollars, and almost fit. It would require machining to match the transmission shaft size.
A new shaft, head, combustion chambers, gaskets, cam bearings, cylinder sleeves, pistons, wrist pins, crank bearings & a long list of other incidental parts were $2500. from IH.

Eaton calls for either conventional motor oil 50wt or you can buy 50wt synthetic.
But straight 50wt motor oil will work just fine.

I've researched at length on the internet. I'm not clear what oil I should put in my axle. The nameplate is battered to the point of not being legible. It is Eaton, on a 1989 GMC chassis I believe rated at 20,000 LBS about 5:1 ratio. What does it need? I doubt the oil has ever been changed. It has about 15,000 miles on it.
