We often run ours 24-36 hrs continuously. On occasion have run up to 72 hrs continuously. I do like to shut down & check oil level every 24 hrs if at all possible. Hard to not be possible as it can be done in 5 mins. or less! But, once in awhile I get lazy and think it's only going to be running another 6-12 hrs so it should be fine to skip 24 hr oil check. Especially since I've only added oil once in 6 yrs and that was getting near service point & oil change anyway.
