Marc,
With a virtual antique as our Onans are, you will be hard pressed to get a lube oil that not effective. A problem with any small engine is that the cooling of the lubricating oil is problematic at best. So, all my small engines use a 10W30 synthetic. Recently, that has been Mobil 1 because of a wonderful casual evening dinner at an SAE conference years ago. Other may have caught up with Mobil, but I don't have freinds in the business anymore. (The luck of those I did have are retired.) One thing of value that I found out then was that while the oil may continue to lubricate a much longer time, the anti-corrosion additives do loose effectiveness due to oxidation. That can't be prevented. They las ta bit longer than a year. So, I don't bother tracking hours onmy small engines (the Onan I do for fuel use) I just date the engine cowl with a china marker.
