SUDT2 hydraulic oil is a Kubota branded product. It is usually only available at a dealership. It is quite expensive.

I ordered 4 gallons of Kubota super UDT2 from Coleman's tonight. I found a spec sheet for the oil and the numbers look a lot better than the conventional UDT oil. Especially during the first minutes on cold start up. Coleman's had a 10 % price cut on the case price plus their shipping to North Central Texas was about 1/2 that of Messicks. Coleman's shows to be in Kansas and I think Messicks is in PA. Its about 6 quarts more than I need right now but its a good idea to have some extra on hand in case a hose breaks and I need to top the system back off..
One other interesting thing about the super UDT2, the spec sheet showed there was a reduced amount of foaming compared to the conventional UTD oil.
Again thanks for all the input!!

I had the same problem with a B20. Water in the oil and air in the oil at start up. I did as advised above and changed the oil out with cheap hyd oil and then in a few months changed it out with Super Kubota.
The thing is I still had problems with air in the oil at start up. It happened only when the air temp was below 50. I kept the machine for several years and would just start it up and if the machine was not operating properly I would shut it off and let the oil settle. I think it had something to do with pump cavitation.
