There is more than the cost of gas to worry about if one intends to run their Onan 5500 24/7.
Here's some of the periodic maintenance Onan recommends for the Onan 5500:
Replace oil and oil filter every 150 hours (or every 6.25 days of 24/7 runtime).
Replace air filter every 150 hours (or every 6.25 days of 24/7 runtime).
Replace spark plugs and fuel filter every 450 hours (or every 18.75 days of 24/7 runtime)
Adjust valve lash every 450 hours (or every 18.75 days of 24/7 runtime).
Filter (oil, air, and fuel) and oil changes on the Onan 5500 aren't very difficult.
Anyone replace spark plugs on a 5500? Difficult?
What about adjusting the valves. Do you have to remove the generator to get access to the valves?
Not sure my original post was clear but My intent is not to run the gen set 24/7 endlessly. I was referring to running it all night to sleep. During the day won't be in the hauler so no reason to run genset. More like 8 to 10 hrs per day for 2 days. Race weekends. Longer summer trips are going to be to the mountains to escape the Az heat.
