Have never seen an oil quality related faiure in anything including drag bikes, race motors etc. Choice of viscosity and change interval dependent on application. The RV onan get annual change as it never sees 150 hours in a year. The champion is every 90 days when we race a lot. The RV has been sitting so likely will change in Nov because we have been on any big trips. With all the rain, we have only raced twice this summer.
Time vs hours/miles is used when oil sits inactive. In Florida swamp if you leave something with open vented crankcase, rust starts. I pulled sons old racecar out and put engine in my car for 1 year. Then pulled apart and replaced rings/bearings/gaskets. They only real downside I found was rust stains on crank journals and cylinder walls. I had periodically run my oil primer to keep engine free. Newer stuff has better control of crankcase venting but I trust new oil more than old.
