- Kubota L4310 GST;Case 580 CK (1968)
I have a recently acquired 1968 Case 580 CK with a 188 cu. in. Diesel. All the old manuals suggest using a single weight oil, but I would rather not have to engage in seasonal oil changes. Does anyone use 15w-40 in their 188? It is what I use in the other two diesels I own and would like to keep them all consistent if I can. What is your experience out there?
