Generator use
I have used my generator intermittently a lot in the past couple of years, but next week, I will need to use it for about 65 -70 hours, non-stop. I know generators are made to be used, but I just want...

Which weight? I ask because your rig is newer than ours. Manufacturers change their specs based on old experience and new developments such as better oils. But the print in the Manuals doesn't morph into the latest recommendations. I've seen that with Ford, both engine oil and rear axle lube. THANKS!!!
I just went outside and checked. As of my last oil change, right now my Onan may have regular Mobil 1 synthetic in it instead of Mobil 1 Extended Performance synthetic in it. I can't always find the Extended Performance version of Mobil 1 in the proper weight at auto stores or in bulk at Walmart (much cheaper there).
Whether I have regular Mobil 1 or the EP version of it in my Onan, I always try to use 15W-50 weight in the Onan. I figure that hot weather is the most likely situation I would find myself in for long Onan run-times (for the A/C), so I use my Onan's hot weather recommended multi-viscosity weight of oil in it at all times so as to be ready for the worst-case situations.
FWIW, I've just started seeing adds for what may be a new version of Mobil 1 synthetic. This new formulation is supposedly capable of being safe for engines for up to 20,000 miles. What this means is it's probably pretty good engine oil in general ... so maybe a good candidate for use in our precious built-in Onan RV generators: https://mobiloil.com/en/motor-oils/mobil-1/mobil-1-annual-protection
