My rig is 3 years old and my Onan 8k diesel has just short of 600 hours and runs like a champ.
According to the Onan techs lack of use is the killer of the generators
I just fired up the two in the shop, small one is 7500k, and twice per year they run and generate just fine. One is 20 years old and the other about 10. Both are gas however but that shouldn't really make any difference.
Given the difference in the apparent construction, the Onan will get run more often for sure. Has to be something in the rotor/stator design that requires the longer run times.
Neighbor here has a 2012, 12k with about 300 hours, treated similarly to mine. Mentioned my issues and he says he will take the chance so we will see. He has made it 10 plus years anyway.
Apparently, the Onan's are the most temperamental piece of equipment on board. And require the added run/load time.
