I pretty much followed this:Alright everyone what do you think,
at 30 hours you need to change the oil. I think they ship them with slightly different spec oil, and it has the smaller OEM Mitsubishi oil filter on it vs the larger Generac one
Break in portable generator
No idea how you'd adjust for a built in generator.
But it makes sense to me that you'd let it run a while with no load, then change the oil before running it under load.
Obviously more work, but hopefully its worth it down the road.
