Good or Bad ?, Running Generator on Eco Throttle

I don't think the fuel quality has anything to do with ECO setting. Most fuel here from reputable companies is = to other countries. Although Shell fuel isn't as good as BP or Caltex or Mobil. Motorcycles don't like Shell and often dealers will tell you not to use Shell petrol.

After the generator is run in, it should be able to use the specified oil or better without glazing. I use Mobil 1 synthetic after it is run in.

Eco throttle matches the engine energy output setting to the electrical energy required to run the appliance. Therefore, the actual Eco speed setting depends on the load applied. It is not just one low speed necessarily. If you fully load it on the Eco setting it will run full output as if the Eco was OFF.
Eco on no load will make it idle. Some load will increase the revs and also the energy output.
It is probably best to run the generator with various items connected at the same time and take advantage of the economy the Eco setting provides without it hammering away at unnecessary high revs.

By running with it Eco OFF, it is running at full governed revs and the full load will be making it work the hardest. Also, higher revs will obviously lessen the life.
The glazing is caused by prolonged light load at lower revs. Unless you continually put it in that situation glazing shouldn't occur. Probably some people unwittingly do create the situation for glazing. Can happen to any engine.
Occasionally give it near full load with Eco OFF to keep an operating balance of use.

Make sure loads and therefore speeds are varied with different appliances/load and Eco will manage the speed/energy required.
If the appliance is something which is starting and stopping all the time then Eco OFF is more suitable as the energy is there available and it doesn't have to catch up everytime the load switches on,eg electric drill driving in screws.

Sounds like a lot of waffle to me.
I have a Yamaha EF2400is – it has no economy idle off switch – it is always on.

As for different fuels - in WA the fuel comes from the local BP refinery - whether it be Ampol, Shell or what ever. Some of the independant operators used to import from Singapore but I don't think that goes on anymore as they weren't up to Australian standards

I think one point also should be mentioned.

In eco throttle the noise level, depending on what you are running off the generator, is generally lower. That is better for fellow campers!

We have 4 EU20I generators in our service vehicles and they run 5-6 days a week on and off on eco throttle and has never missed a beat....... and they don't get serviced as often as the should..... we have never had a problem with them and they have never let us down.

Our newest one is now 3 years old.

Think your original question should go down as a urban myth like so many other misconceptions out there..... did you ask they ones who told you if they have ever had this problem and if the use a Honda or Yamaha generator..... maybe they sell another brand?

If they did have an issue don't you think Honda and Yamaha would of addressed it by now or remove the eco function.

Hello Peter
Here is my five bob's worth. Cylinder glazing leading to poor oil control used to be quite common in engines and I'm sure it still happens when engines are run at light loads for long periods. My experience is with large engines, but I'm sure it can happen to smaller engines too. I saw it many times with engines fitted to cranes, where they were sized for very heavy loads, but only lifted heavy loads once in a blue moon. The rest of the time they idled doing nothing at all. The other interesting point is that only the very occasional engine glazed. I also saw it with generator sets with similar load requirements. The problem is that once an engine glazes, often the only thing that will fix it is to strip it down and lightly hone the cylinders. Very expensive!
The trick is to give the engine some moderate exercise from time to time before the problem develops. I am very gentle with my diesel ute and consciously drive it hard up a long hill from time to time to loosen up the piston rings. Then I go back to trundling around!
So my suggestion, if you are concerned about glazing, is to connect your generator to a decent load from time to time. I dont know how big your generator is, but perhaps a couple of electric irons might do the trick, and the thermostats in the irons will vary the load a bit which will do your generator the world of good. Just make sure you dont overload it.
And if you use the time to do the household ironing, you will no doubt be a very popular guy around the house at the same time!

Peter.
I am pretty sure that the cylinder bore glazing is caused a lot more by running the generators or any engine petrol or diesel on light or no load for extended periods of time. Turning the eco throttle setting off only speeds up the engine and does not increase the load.
The piston ring design is such that the combustion pressure forces the rings against the bore to assist with sealing. When the engine is not under load this pressure is very much reduced and so the rings polish the cylinder surface.
Hope this helps a bit.

The most common sense approach and one I use is to mix both on and off. Certainly from a maintenance standpoint when I start a gennie I haven't used for a while I turn Eco off after it has warmed up. The only issue I have ever had is stale fuel after inactivity and this is more me being slack.
