I believe there is now No oil that meets SUDT. There was one claiming that it did, but Kubota took them to court and won because it fell so short. It was more like UDT than SUDT.

I threw in a few Kubota oil and hydraulic filter numbers for my B3030 and ZD323 but your site came up empty. I also tried an oil filter for my Generac and that too wasn't listed.
For many Kubota HST hydraulic charge filters there is no cross worth taking the chance on.
Have a Generac 20Kw aircooled that takes the long oil filter and the kit with air filter, oil filter and plugs is less than $15 on Amazon buy 2 or 3 and it will make free shipping. Otherwise Ziller electric had #070185F 5 pack for $40. Not sure what an automotive cross would be.
