Paul the trouble is if you use this cheaper 303 oil in a tractor that has clutch disks or brake disks that run in the oil it can ruin those disks. I know they are saying 1974 and newer but heck older JD tractors had wet disk brakes too. So I am not 100% sure what the issue is with the 303 rating. JDs oil was called 303 until the mid 1980s IRC.
All I do know is this cheaper stuff can cause trouble. Had a customer buy a 55 gallon barrel. HE changed the oil in his JD 7600 and within 10-15 hours the transmission started slipping. I tore into it. The shift pack disk looked good other then the facing was no long glued to the steel center. What ever is different in the oil caused the facing to come loose on all the disks. So we had to complete replace all of the ones in the transmission. Then we also replaced the brake disks too. PTO clutch and main clutch too. Total cost for parts and labor was over $8500. Tractor only had 1700 hours on it. So his saving $300 on a barrel turned out to not be too good of an investment.
I tell everyone to use a HyGuard or HYtran rated oil. It even works better in the older stuff as it has more anti- moisture additives.

The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
