"Vintage" oil is a marketing ploy, and not always less expensive, at least to the buyer, as you noted. Do a bit of research and I believe you will find the "modern" oils/fluids are backwards compatible to the "older/vintage" ones. Why would a manufacturer want to add more products to stock and deal with, other than in the cases where the product was going into new hardware that is not similar to existing. John Deere doesn't sell 303 Special Purpose Oil, J14A Hy Gard, J20A Hy Gard, the current J20C covers all of them. Same applies to the AGCO fluids I believe. Look at the manufacturer specs an oil/fluid covers and go with the newest. And if you cannot find the specs for a product on the container, or a Product Data Sheet for it, I suggest avoiding use of said product.

I bought 10 five gallon buckets of TSC Premium universal oil for $10.32 per gallon, including tax. It was on sale for $15 off per bucket plus $5 off for 10 or more buckets. I know I'll use it, unless I croak, and then someone will get a good deal on a bunch of oil! I've been using the T6 in my Cat powered Freightliner, seems to start easier and still has decent oil pressure after it's hot. I just use regular 15w40 in the other equipment as they aren't started when the temps are cold.

Backwards compatible, yes, exactly my point earlier as well! Agreed!!

Will Prime Guard 20w general purpose oil work as a 821 substitute in a 5015 ?

I think the 5015 came originally with 15W40 in the trans / hydraulic system.. That is engine oil, so the system must be pretty basic. Any hydraulic oil would be an improvement over engine oil, in my opinion.. Hyd oils have anti foam and anti wear addatives for pumps and valves. Engine oil is made as a bearing lubricant.
That being said, i think the PRIME GUARD "general purpose" does not list any SPECS. It is the cheapest type of hydraulic fluid you can buy.. Not saying it might not MEET any specs, but they didnt test it to verify and LIST ON THE CONTAINER.... I would go with a PREMIUM that lists a few specs like 821, TO2, etc

My AGCO dealer always sends me what the good Dr mentioned. AGCO 821XL Permatran. They told me it is to be used for hydraulic and transmission in the Allis-Chalmers D series. WD as well. The color is gold.
