In this video, I show you how to change the oil in your Onan MicroQuiet 4000 RV Generator. I also discuss how often to change the oil, how much oil my generator takes and what special tools are needed.
MORE ABOUT THIS EPISODE
Full step-by-step instructions and parts list here:
rvwithtito.com/articles/onan-...
Performing regular oil changes on RV generator is important for keeping your generator functioning properly. You should change the oil at least once a year as recommended. Also, be sure to run your generator for at least an hour every month. While exercising your generator, turn on a few electrical components so that it has an electrical load on it.
I have an Onan MicroQuiet 4000 generator which does NOT have an oil filter. For other models, be sure to reference your owners manual for proper procedures and instructions.
This video is also addresses these topics:
Where is the drain plug on my onan generator?
Onan generator oil
Onan generator oil capacity

+RVwithTito In the video I did not see about changing the Oil filter and Air Filter. How often do you do that as well

@RVwithTito 8 лет назад

+2nd Home Tx My generator does not have an oil filter. As for the air filter, I switch it out every other time I change my oil. I just don't use my generator that much so the air filter stays pretty clean.

@2ndhometx21 8 лет назад

@vernsquash8883 4 месяца назад

Excellent video overall. I have wondered how those ENCLOSED generators get oil changes, and now I know. One thing to understand however, is that quality oil does not deteriorate by itself in 12-months. If only a few hours of use is put on an engine, it is not necessary to change it every 12-months. That is a direct quote from a long time friend who worked at the MIT Sloan Automotive Laboratory.

@tetranz 3 года назад

Thanks for this. I did it on my QG 4000 this morning. I think that's the same model as the MicroQuiet. They changed the name. A note for anyone with the QG 4000 is that the drain plug needs a 12 mm socket, not 9/16 in. I guess the newer models are metric. I also did the fuel filter, air filter and spark plug with a maintenance kit I bought on Amazon. The fuel filter needs a 9/16 in long reach socket.

@badactor3440 4 года назад

Although SAE-30 is good, 10W-40 or 50 is better for desert areas or hot climates in general. It is not necessary to warm up the generator before you drain the old oil, especially if it hasn't run for a while. Do not hold the stop button down. Simply push it and immediately release or you risk flooding the engine and leaving fuel in the carburetor. The electronic shutoff mechanism is designed to burn off any remaining fuel in order to empty the carburetor. Remember, the stop button is also the primer.

@BigBilly1958 11 лет назад

Nicely done sir. Very informative and easy to understand. Can't wait to change the oil in my Onan in my Weekend Warrior. What software do you use for your editing and graphics?

@mikelochmann2027 3 года назад

Tito post's a video on how to change generator oil then shows you how NOT TO CHECK OIL LEVEL. When checking oil level you don't screw dipstick in. Level is checked by inserting dipstick until it touches top of fill tube, then withdraw, check level on stick, TITO!

@kittykat999a 6 лет назад

@2ndhometx21 8 лет назад

This is a totally awesome video, hey do you know of any rule about the first oil change you do and when. I heard on my walk through it should be done at 20 hours. then every 100 after that, does that sound correct?

@RVwithTito 8 лет назад

A 10 to 20 hour break in period is usually standard on other generators. I'll have to double check to be sure. After that then every 100 hours or once a year, whichever comes first. I just do mine every spring.

@DebbieTomkoSUNSHINE 2 года назад

Thank you. When I bought my new RV, I didn't get any manuals or books on it. Your video was helpful. I was wondering if there's an oil filter that would need replacing, like on a car engine?

@RVwithTito 2 года назад

This one doesn't have an oil filter, but the larger ones do.

@bookMEinnet 7 лет назад

What kind of oil do you need to put in? That was perfect and do you also have a video for the changing of the fuel filter? The air fllter is a no brainer but can the air filter be cleaned? And if so with what?

@jeep146 3 года назад

Most smaller generators do not have oil filters. I think the reason is hours. Small generators that they sell with wheel kits are changed at 20 hours. Larger generators 100 hours. The big generators that power buildings can go weeks but they have filters. In short change your oil when it is time to prevent damage. The other problem is to be sure to turn on lights or whatever you run to make the engine speed up. It's like a car that just sits at idle all day. It needs to run on the highway now and then. The generator is the same it needs to work or you could have problems after time.

But got it done. running smooth but I have a problem and hope you might know the answer.... Got it running but no juice to Microwave/AC inside MH. Any ideas? did you have this issue when you replaced fuel filters?

@RVwithTito 4 года назад

I didn't have that issue. The generator AC output should feed your distribution panel (possibly via a transfer switch) and should not affect individual circuits separately.

@666NOT Год назад

Here's a little secret I found out. If you're only and runs for awhile and then shuts off and then cools off and starts up and runs for a while and then shuts itself off you've got a little bit too much oil in it. It's all gets hot and expands in the overfill shut off kicks in. Take a little oil out see if that doesn't fix it. Someone else probably commented this already but here you go

@RVwithTito Год назад

Yes I've heard that one too but didn't know that there was an overfill sensor in there. Thanks.

No oil filter on this generator. Check your manual, some Onan gensets have a filter.

@trustme7731 4 года назад

Lots of people are claiming that 1.6 qt.s and the full mark on the dipstick is over filling and causes a shut down after 20, 30 or more minutes of running time. I can't explain it, but thats the claim.

Both would work. Check manual. I prefer single weight oil as the single weight oil stays up in the engine longer after shut down. So when I restart I already have some residual oil on the rubbing components. If you have a lot of cold weather operation the multi weight oil might be a better choice.

@bobgil3464 6 лет назад

Onan manual says both SAE 30 (0-100 degrees) or 10W40 (10-100 degrees) will work in this model engine. The SAE 30 is the preferred summer grade and the 10W40 is recommended all year use.

have you ever heard of people filling the oil only slightly above the "add" line in situations where the generator will run and suddenly shut down after 30 minutes to 60 minutes.
