Somehow I missed your Post 14 and didn't realize you had it going. Stay with the oil recommended by Onan...period. Viscosity shouldn't cause the problems you were having nor would changing viscosity affect ability to cool. While oil circulation is a factor in the heat reduction process, airflow is the biggie there. Mine is water cooled. If yours is also, check coolant level. If not, open cabinet plates and make sure nothing has built a nest anywhere, interfering with airflow.
