KodiakRV said:I've got that model and I changed mine a couple of weeks ago. It's easy as long as the RV manufacturer didn't install it with a brace blocking the drain hole. The manual instructions say it all... [my comments in brackets]
1. Run the engine until warm, stop it and remove the oil fill cap.
2. Remove the oil drain hole cover in the base [2 screws], place a pan underneath and unscrew the drain
plug [a hex-head bolt]. Let all oil drain from the engine and then secure the drain plug. Torque the
plug to 21 lbs-ft and secure the cover.
3. Refill with 1.6 quarts (1.5 liters) of oil. See ENGINE OIL RECOMMENDATIONS [table below].
Check the oil level and add or drain oil as necessary.
4. Screw the oil fill cap back on securely.
TABLE 1-1. OIL VISCOSITY VS. TEMPERATURE
EXPECTED AMBIENT
TEMPERATURES SAE VISCOSITY GRADE
32? F (0? C) and higher -- 30
10? F to 100? F (−12? C to 38? C) -- 15W-40
0? F to 80? F (−18? C to 27? C) -- 10W-30 or 10W-40
−20? F to 50? F (−28? C to 10? C) -- 5W-30
Any SJ rated oil or better will work I recommend Mobil 1 10-40 for year around use.Fcranger said:I think Onan recomends to change the oil in the generator after the first 20 hours of use.
I have not used it very much since I bought it, I have almost 20 hours on it. most of it half hour run times a month to exercise it. haven't had to use it steady since all the campgrounds had electric hookups.
How much of a job is it to change the oil myself? I take the motorhome to Oil Can Henry's for oil changes and they use Mobil 1 synthetic in the engine, is it okay to use the same thing in the generator? its a Onan Microquiet 4000 ???
blw2 said:sorry for derailing, but something that I've scratched my head about is the whole running with 50% load thing. About the only way I can put that kind of load on mine is to run the AC...... doesn't make much sense to me...... for a fixed 2 hours per month especially without short runs
what i can do is run it for a period of time, maybe 10-15 minutes, 20 minutes, maybe an hour or more on occasion. Sometimes I would have the AC on, but sometimes, like now the load would be a little battery charging and lights etc.... Sometimes I start the genny for just a minute, to check the hobbs meter or brew a cup of coffee
One our recent long trip, we ran a total of approx 15 hours on the genny. It was up and down. Sometimes only for a few minutes, sometimes for more than an hour. Just normal living. Is that really bad for it?
NOW, Back to this thread topic, I was actually planning on looking in the manual this weekend to confirm the service intervals to see if I'm due for anything. Currently just under 28 hours total on it, and had the dealer change the oil when I bought it since it had been sitting on the lot for a year....... so based on this thread, I guess I'm good for now!

Rene T said:I believe Gary answered your question on January 10th. Posting a reply like you just did will not make you many friends. All you would have needed to do was post the question again maybe in a different way. : Have a nice day.
WILDEBILL308 said:I am trying to get this straight soyjer. You didn't post till 27 post after this thread was started by Fcranger. You technically "HIJACKED" the thread and now you act like, well I am not permitted to say. As they say on Shark Tank "I am out" on any future post you make.
