Recomended oil for Onan 4KW generator
Hi We have an Onan model 4KYFA26100K 4 KW generator in our Class C and were wondering what is the recommended oil type for it? Thanks.

15W40 is probably the hot tip if you are going to be using the generator underway due to the increased temperatures under & around the RV.
While you can use a diesel 15W40, I'd suggest getting the real deal by Onan. Or an oil engineered for aircooled motors. Aircooled engines require a different additive package than diesels. Change the oil by the Onan schedule.
