WHEN TO CHANGE OIL FOR MOST GENERATORS - OIL CHANGE SCHEDULE 

I recommend the following 10W 30 oil for your Generator: YAMAHA LUB-10W30-GG-12 Yamalube Golf Car and Generator Oil 10W-30 - Quart 👉 👉 ✅ ✅ amzn.to/3kHZDLH

I have a Champion 2500 Dual Fuel Inverter. I used a magnetic dipstick, I used their break in oil for 5 hrs, got a fair amount of metal shavings, ran it for another hr, changed it.....very little metal showing. Took it to ten hrs and changed again.....no metal showing.......I'm good for 50 hrs at least. I'm using AMSOIL Small Engine 5/30.......love it!

I wanted to know when to change oil for my generator. Thanks for this video

Perfect! just the information I was looking for

If we do a little math and compare to your daily driver. Also take into consideration that oil not only loses viscosity but it also gets dirty from combustion blow by. Same way your car gets black oil from combustion soot. Most generators are carburetor so not as clean a burn as a car that is fuel injected. carb engines makes for dirty oil and generators are running at a high RPM with most units being single cylinders air cooled and with no air flowing over engine like a air cooled motorcycle, They run pretty hot and they are working hard 24/7 with very little cool down periods especially during a power failure in the south. If you start a road trip in a car with fresh oil and run it at a high RPM , Say 3000 RPM Lets just say 80MPH non stop for 24 hours straight. You will cover 1920 miles. Now double that = 3840 Miles. In two days its time for a oil change. Remember , Your car is liquid cooled and multi cylinders and fuel injected so cleaner burn means less blow by soot = cleaner oil. Most generators only use 1 qt or 1 1/2 qts per fill. So running 12 days straight changing every 24 hrs is not a bad price to pay. We are just talking about your basic stand by people have in there garage. These little engines are being punished. Now if you have a larger generator that runs at a lower RPM, You can go longer between changes. If you have a nice little three cylinder diesel , Liquid cooled like I do , It can sit there and purr for a week before a drain and fill.

nice and simple information. some manuals say hours of run time OR each year, i think each year is pointless if you only do a 30 minute run-test every other month.

20 hour oil change service intervals after break in of 40 hours? Something seems wrong here. Those engines must be using tin foil for steel or have an oil reservoir grossly undersized. I've owned two B&S powered 5550w generators for nearly 40 years first one lasted over 20 years. I power my whole house when the power routinely goes out, running up to 48 hours at a time. I change the oil once a year or the 100-200 hour range. From my experience, the generator portion will fail before the engine does.

I let mine go 55 hours on Castrol Synthetic oil 5w-50 in warm weather. It came out a silver soup. 10w30 in cold weather is fine. In hot weather? That dog won't hunt. I use 40w and in 100+ degrees 50w VR1.

Every 20 hours for an oil generator change seems wrong. 1 tank of gas for break in oil. Every 50-100 hours oil change time. Heavy load 50 hours, 50% load 100 hours.

Damn that's crazy you would go broke changing all the Dango oil all the time I'd be a lot of money change the oil almost every other day if you live camping

Changing oil every 20 hours??? Here in florida we lose power for 7 to 14 days during hurricane season so each day running 20 hours I need to change oil makes no sense!!

The manual for this duromax states after 20 hrs, THEN next change at 50 hrs, then 100 hrs, so something messed up doing 50 then 20hrs. Debris from new engine dictates more frequent initial change on any motor!!

What if I never changed it ever since I bought it ? It dosent turn on now

I change it with 10/30 every 50 hours of operation and it looks pretty black. Wouldn’t advise going past that.

How many hours would these engines last with good maintenance?

Should I use 10W40 for hot Asian country

My 20,000 Watt Kohler Generator says about 100 hours then change. The dealer said 50-100 hours.

I the users manual it says every 50 hours

That is a completely ridiculous recommendation for most generators. Folks please do more information searches before following this recommendation.
