I have a 15k Generac generator and am wondering how will it

Customer Question

Hi, I have a 15k Generac generator and am wondering how long will it run until the low oil button comes on. It is 9:00 p.m. here in Michigan and it has been running for at least 4 hours.
JA: What's the make and model of the generator? And can you guesstimate how old it is?
Customer: It is a 04390-2 I believe and was installed in 2002. I just had it serviced in June of 2016. It is a Guardian.
JA: Do you plan on doing the work yourself?
Customer: It would just be adding oil. I know it will not run without oil.
JA: Anything else we should know to help you best?
Customer: I am not really sure what else to pass along.

How long it will run depends on many factors. There is no set time.

If the unit has been well maintained, and the engine is tight, it could run for weeks.

If the unit has not been well maintained, and the engine is worn out, it might need to be topped off with oil every day.

I recommend shutting it down and checking the oil at least every day, if not every 12 hours.
