I agree that oil consumption "appears" to have improved. I'll continue to monitor and keep measurements and data as correct as possible. When working with only a 400 ml. fill, it doesn't take much to effect the measurements. If the generator is even on the slightest angle, the correct fill can be thrown off. The good news is that Yamaha provided a three year warranty (5 years now if bought before Oct. 31st). I've got plenty of time to see how things develop. The down side is that with a possible oil issue, the longer I wait to make a warranty claim, the more resistance I may receive from Yamaha account more time on the machine. I'll probably contact Yamaha soon to advise that the machine is using excessive oil but I'm willing to wait to see if consumption improves. That way I'll have a complaint record on file.
I intend to continue the use of conventional oil. At least until the machine gets to normal oil consumption levels - which to me should be none.
Regarding less oil consumption at higher loads. On a new/fresh engine, you're probably right. However, from my experience, most engines with oil consumption issues, when pressed hard, tend to use more oil.
Other than the oil issue, it's an excellent little generator. Certainly more refined and well built than most I've seen. However, the Hyundai looked very well built too until it went south.
The EF2000 is super quiet and fuel efficient in eco mode and lightly loaded. I see regular returns of 3+ hours per litre with loads under 500 watts.
Really, the oil per se' isn't the issue for me. It's the additional requirements to monitor oil level and top it off as required. My introduction to the oil consumption problem was when the oil level alert switch started to actuate at around 70 hours after the last fill.
Maybe I'll just lower the oil change interval to 69 hours from 100? NOT!
