As far as ECO mode not providing better runtime, some others have noted that above 1300W, it doesn't help. Why it hurts though - don't know, not my data.
The reason is because an inverter generator saves fuel by throttling back at lower loads. If it doesn't throttle back because the load is high enough to keep it at high rpm - then it saves no fuel. It burns the same amount of fuel as any other 100cc engine would with the same load.
Economy mode is the mode that throttles back. Turn it off, and the engine runs at full speed regardless of load. Even with it on, at some point the load will be enough that the engine runs at full speed anyway.
So it would appear, that 1300w is the breakpoint where the engine is running at full speed and that is why economy mode saves no fuel at that load level.
