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.
