I have UDT2 hydrologic oil on hand. Can this be used for a Case 580c backhoe?
Hydronic and hydrologic oil??? What is the oil originally for? It sounds like it's a special oil for hydrostat drives like Kubota possibly. If you're looking for hydraulic oil, I think all you need is a good 10w or AW32 hydraulic oil, nothing special. Still best to check the manual but I think a 580C is just a gear pump and doesn't need any kind of special oil.
