Hello, I just bought the Champion model #200973 3650-Watt Dual Fuel Generator and I'm wondering about the oil. Initially I had thought about going with a synthetic oil due to a slightly wider temperature operation range and I posed a question to Champion support with that in mind, which by the way they have fantastic support I'll post their response below. I since have changed my mind (I think) and will probably just stick to a standard 10W-30. I haven't put the oil that came with it in yet and I'm wondering if I shouldn't buy a different oil, a "better" oil? Maybe something from Castrol that I could leave in instead of flushing after the break in period just to go synthetic. I'm new to this and unsure what would be the best. Any suggestions?

Font Material property Rectangle Parallel Number

During the initial five-hour break-in period, we recommend using standard 10W-30. This type of oil makes it easier to seat the rings of the piston. Once the break-in period has been completed, be sure to flush the oil. You can then use the 5W-30 synthetic oil thereafter.

During the break in period stay at or below 50% of the running watt rating and vary the load occasionally to allow stator windings to heat and cool. As with all new engines, the piston rings and cylinder need to be broken in. This is important for the newly manufactured cylinder wall and rings to seat themselves.

It is not necessary to run the generator for five hours straight to do the break-in period. The generator can run for five hours over any period up until they reach those five hours.

I live in Georgia. I settled on the Amsoil Synthetic Small Engine Oil 5w30 and ordered 2 quarts online. The generator only holds .6 quarts so that will be enough for 1 fill and 2 changes. The manual states a change is needed after 50 hours under a heavy load or after 100 hours/annually.

I don't get lengthy power outakes very often here but I bought it just to have a backup (mainly for the refrigerator), just in case.

I assume since there is no oil filter, swapping from standard to synthetic oil is just a matter of draining the oil and then refilling it with synthetic.

We’ll you paid less than the silly Amazon price, but now that you know what you have….keep an eye for some retailers that might sell it. Here in Canada some TSC stores carry it. My preference would’ve been the 10w30, but not a big deal. Seems Champion likes the 5w…
Yeah I'm sticking the the manufacturer recommendations of 5W-30 Synthetic. In addition to the graph above the manual states:

"Synthetic oil may be used after the 5 hour initial break-in period. Using synthetic oil does not decrease the recommended oil change interval. Full synthetic 5W-30 oil will aid in starting in cold ambient < 41º F (5º C) temperatures."

I'll have some extra oil and a backup recommended NGK (7133) BPR6ES-11 Spark Plug set away just in case.

I do plan to due my first oil change sooner than recommended to be sure everything is clean internally. I'll probably stick with standard oil until that 2nd change before going to 5W-30 synthetic. Maybe after 15-20 hours usage and then go to the recommended schedule.

Well seeing as I'm surrounded by like minded people that think having a backup generator just makes good sense, I'll show you the complete package I bought. I think some of you will appreciate it.


As I mentioned, I bought the Champion model #200973 3650-Watt Dual Fuel Generator


The Champion Medium Weather Proof Cover (This will be on when it's stored away)



The Champion Storm Shield Severe Weather Cover



... and a Champion 25 ft. 30 Amp 125-Volt Fan-Style Flat Generator Extension Cord (great for going under doors)

Always happy to see someone join the Champion team. I've got two of them, both dual fuel. I've got a 100296 bigger one and a 2000W dual fuel. The plan being to run the little one at night, just to run a small window A/C and the fridge, saving a bunch of propane overnight. I've only run mine on propane and would prefer to keep it that way. As they are just for back up emergency power, it saves the whole gummed up carb problem. There is a lot of good advice here so as not to have the gas problems. So, if your primary fuel is going to be gas then I would do some research here.
I plan on doing the same but will be prepared to run on gas if needed. I know that you do get a bit longer runtime and a bit more power using gasoline but I don't mind. I have my generator actually stored, for now, inside the house. I dont have a garage or outdoor storage shed and running it on propane will keep it from smelling like a gas pump.
