If you have a late model RV I would at least run a semi synth. Chevy has been specing 5w30 Dexos for a few years now and only a semi or above will meet those specs. Ford has been recommending 5w20 Semi for at least 5 years now. I am sure that a dino oil will work but the oil reminders have been programmed with the factory fills in mind.
