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...

"Sure seems like there ought to be more conclusive oil testing data somewhere."
There is. Unfortunately its proprietary and not given away to the general public freely. I have to agree much of the data (although very repetitive) in the referenced link by 540 RAT though. The ICP (Inductive Coupled Plasma) oil analysis tests thought so highly of at BITXXXG aren't worth much and there's no point in trying to explain that to BITXXXGers or anyone else without several years of chemistry under their belt.
Onan doesn't manufacture/blend oil. Onan manufactures generators. Any lubricants with the "Onan" name on the container are manufactured/blended by others, marked up and sold under the "Onan" label. If you meet/match/exceed the API specs on the Onan label, use the proper viscosity based on operating temperature, and change the oil regularly based on environmental conditions, you'll be fine. It's not rocket science but it sure gets a lot of press.
