After reading probably a thousand posts, and dozens of threads, probably hundreds of pages, I'm now more confused than ever, and my head hurts.
I'm making a list of fluids, and in searching, the amount of 'use this, not that' followed by 'Make sure you use that, not this' is making my head hurt.
So far, what I've learned is....
1. Make sure your GO is yellow metal safe, but it doesn't matter because if it's not yellow safe it won't hurt it.
2. Use high zinc oil, except when you don't use high zinc oil because of added wear.
3. Don't use 30W in your transmission, unless you use 30W in your transmission. Also, ALWAYS use 80w90 in the transmission except when you don't use 80w90 because the manufacturer only spec'd 80w90 for the Army and not in other vehicles the transmission was used in.

Is there a general consensus on this now?
Oil isn't critical, so I plan on just getting the 5 gallon jugs of Travellers 15W40 or whatever is on sale.
The other question is GO for trans/TC/Diff.
Is there a reason why I shouldn't be using the travellers (Tractor Supply) 80/90 in everything?
Modern day oils, even the cheapest out there, are 10x better than some of the best oils these things saw in service 60 years ago, so... Is it really that big of a deal?
