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...
I have run over 10 Onan 4000 KY over 2500 each with no problem. Check the oil every 8-10 hours. To check the oil, turn off the AC, let the Generator run for 4-5 minutes to cool down, turn it off, check the oil, add if needed, start it up and continue to run. I have run them for up to 110 hours straight this way several times, no problem. I do use synthetic oil, no regular dyno. Temperatures are too high so you can really use synthetic oil for this application.
