I know UDT (20w) is single weight and Super UDT is (10w20) multi-viscosity. By accident I put UDT in my tranny instead of super. Is this a big problem? :confused3:
Super UDT and Super UDT2 are not synthetic. Check Kubota's website. I would think they might mention it at least once if they were. The local Kubota parts guys laugh because the literature says it has synthetic LIKE properties.
I would never have either of them as I said the $35 for 5 gallons of Travlers UDT has always been perfect & they have always had it in stock @ that reasonable price... KennyV
I wouldn't worry about it. The newer additions are lighter weight to allow the oil to get through the system better when cold weather hits. This is not a problem in warmer areas!
We have had excellent results with all or the Kubota oils and with installing it in other makes of tractors have had excellent reports from the owners of the hydro's that they are quiter and seem to be more reponsive.
IH part of the CaseIH line-up was actually one of the first companies to mass produce hydrostatic drive tractors and their oil labeled hytan was my favorite for years but we find he Kubota oil works well in the CNH hydro tractors very well actually better! I do like the Hytran because of the condensation we have here in the North east from winter as it can absorb a lot of moisture so we don't waste hydraulic pumps like with lessor oils.
