That is not many hours on the engine and your problem might go away with longer operation at operating temperature. You should check to see if it is as it will cause cylinder glazing the same as your other diesels if the thermostat goes bad.. The oil change from deere to rotella will not gain anything as they are both close in spec's and additives and I don't believe that is a problem. A change to 30 fixed weight might slow the use of oil for you.
