I have just purchased two Yamaha EF2000is generators to use with my 5th wheel. I plan on using both of them in parallel to run my AC.

The recommended engine oil from the owner’s manual is:
YAMALUBE 4 (10w-40), SAE 10W-30 or 10W-40
Recommended engine oil grade of API Service SE or higher.

I understand that with splash oil systems that shearing the oil is a big problem. I also understand that multi grade oil, especially 10W-40 is highly sensitive shear factors.
I can change both generators with one quart of oil, so the cost per quart is not a big factor. What is a big factor to me is: I would like these generators to last me as long, if not longer, than my last generator. I had it for 35 years. It’s terrible noisy and the power that it put out is not very clean, but it still starts and runs well. I hope to use these new generators a lot more than the old one. I always used Stabil in the fuel and changed the oil as soon as it started to look off color. I always used Pennzoil or NAPA and 30 or 10-30 depending on the temperature.

I purchased enough Yamalube 4 for two oil changes. I am 200 miles from a Yamaha dealer. What would be a good substitute for the Yamalube 4. Should I be using a 10W-40 at all do to the shear factor? I would also consider a synthetic if it was readily available.

I think GC 0W-30 makes a GREAT OPE oil - that's what I'd use.

You don't need that over priced and hard to get yamalube,go to wal-mart and stock up on some 5w40 HDEO, a HDEO will protect better,them gens will out last you!

Heavy duty engine oils made for diesel and gasoline engines used for industrial applications or hard use are excellent lubricants for small engines. Rotella T, Delo, Delvac are a few brand names that sell HDEO in various weights. I use 15W40 Rotella in a lot of applications from motorcycles to lawn mowers. Great stuff at a great price.

The Rotella T5 10W-30 would be an excellent oil for your application. Believe it is available at most Walmart stores.

I remember using Yamalube 2-stroke oil years ago when I had a new Yami Waverunner (back when I could actually have fun things). It was outstanding stuff.

I'm glad to see Yamaha recommends a 40wt for these little buggers given they only hold a half-quart.

My only concern with a 15w40 or 10w40 would be for the extreme cold Montana can get. My company has some plants in Butte. It gets like -45degF there in the winter. It's not fun. If that's the case for you, I'd go with Shell Rotella-T 5w40 synthetic. It's perfect for both worlds (Hot/Cold).

My dad and I both have an EF2400is. It gets Chevron Supreme 10w-30 just like every other Yamaha 4 stroke I own.

good stuff.


This is a good list. I use Esso XD-3 0w-40 HDEO in my Yamaha ef2400i generator, and have had no problems. I would also use any of the above, but the XD-3 is the best value around here for an full PAO synthetic HDEO. I would also

Given your climate, as I see you have a similar one to me, I would say that a 0w-40 or a 0w-30 would be perfect. GC, M1 0w-40 or a 0W-40 HDEO are your premium choices in my books. For availability, you'll probably have the easiest time finding a 5w-40 or 0w-40 HDEO in any town. Billings would likely have just about anything on the list.

Some kind of synthetic sounds like a very good idea. I just need to look around to find what is available. The generators were delivered last evening. They look really nice. I am really looking forward to trying them out camping.

I love my 2400. It will run the rooftop air conditioning on our 25' travel trailer. It's really quiet and starts easily. I thought of daisy chaining 2 smaller ones, and thought I didn't want the complexity since we only use the generator for running 120v things where we have no hook ups. After lifting the 2400 in and out of a 3/4 truck bed whenever needed, I wish I had the two smaller ones. Would be far easier to lug around.

We don't use it for battery charging (which makes sense for a smaller generator) since we are pretty conservative on lights etc., never use a TV and typically go for 2-3 day outings at most.
