Onan BFA Oil - Why not 20W-50?
Note: Our typical camping climate range runs from 10F to 115F (if we go to Redding, CA in the summer... otherwise up to about 105 in Southern Oregon.) Clearly Onan/Cummins have updated their recom...

I'd use the same 20w-50 you use in your 454.
But since I am spending your money, perhaps mobil1 5w-50.
Oil is a lot more than just its viscosity. ZDDP levels, Boron, Moly, HTHS viscosity, resistance to shearing, fuel dilution, oxidation, are all factors avidly discussed on Bitog.
Also the range of viscosity to meet a -30 or -40 specification is quite wide.
I don't require synthetic or a 0winter in southern california, oil but use Mobil1 0w-40. It requires more group4 PAO and group5 ester oils to meet the 0w rating, also meaning less viscosity index improvers and pour point depressants.
Unless of course, oil is oil in one's mind. Then just go seek out some citystar.
