It depends on what generator that you have. You can do a google search and find the manuals online and they will tell you almost everything about them, and you can print it out for future reference.

Follow manufacturer spec. If you dont put the stated miles on in a year then do oil and filter annually.

I just did the maintenance on my genny in April.

Oil and filter, new air filter, new plugs, removed the slip-ring brushes, inspected them and cleaned the slip ring. Total cost about $15

I'm good to go for another 50 hours.

It won't do MACH 2, but I can get a sandwich and take a pee.

Also you should clean the spark arrestor .

Ok, driving to many hours driving that day.

should read

how many hours do you change the oil, fuel & air filters?

I have an 8,000 Watt with 350 hours.

I don't have any history on maintenance from prior owner.

Just did the oil, looked like mud, oil filter looked original and hard as heck to get off think it was original.

found oil @ 150 hours along with spark arrest
Fuel & Air @ 500


So at 500 I'll do all

Gee almost exactly my findings too. 300 hours, and I'm sure it was never changed either. Did my change and will do another at 500 hours.

350 to 500 hrs for service....??? YIKES!!!! I do mine every 100 hrs. I have only a 4000 but I clean the air fins with compressed air, change the air filter and change the oil. It has no filter.

I have an Onan 4000 Micro.

Generally 150 hours for oil. You go by the Hobbs meter on the dash. Not really necessary to do it annually like you would a car. Why? Because cars run at varying RPMs over the course of a OCI whereas a generator runs at a fixed RPM ~2000-2400RPM which is a lot easier on the oil.

I usually pull the spark arrestor and run the generator for 10-15mins every 150hrs.

500 hours for spark plug and air filter.

I generally don't put that many hours annually so I change once per year. Got 330 hours on a Marquis Gold 5500 in 11 years of use.
