Hey everyone i have a 2012 rmk 800 for the first time. It has the plug for the 2 different octane fuels. Any major drawbacks to running 87 with 10% ethanol or should that just be used when you are in a jam and cant get premium. There are so many places i go that i cant get anything but 87 with ethanol.
What fuel are you using

I personally will not run ethanol fuel but to each their own. Just be aware that plug has nothing to do with premium or regular it is ethanol and non ethanol. Not all premium is non ethanol and not all regular is ethanol.
^ I disagree to a point. Eth setting adds fuel, because eth gas has less energy per unit.
By the same token, an engine designed to run on premium wants the slower/longer burn of premium gas and low octane can be combatted by the eth setting, giving the engine more fuel which will help offset the quick burn of low octane and help prevent detonation (which isn't as much of an issue now with det sensors that pull spark timing accordingly).
To the original question, in my stock 2012 Pro, at lower alt, never had it over 5kft, I've run non e premium, non e 90 octane (Alaska gas) and ethanol premium all with zero issue or det on the non eth fuel setting.
If I filled it with 87 I'd pull the ethanol plug.

If in doubt run ethanol setting. Safest alternative. And if it is ethanol try to run it all do not let sit over 30 days without using a stabilizer such as Startron. Or another Enzyme type stabilizer.

I had an 04 kitty cat with a switch which im guessing was the same. My understanding of it was that for lower octane and ethenol it put 3% more fuel. The first year i always put preium in but after that i used 87 with 10% ethanol and honestly i didnt notice a difference how it ran. I did always store it with no ethanol in it. I think i will try the 87 and see how it goes, its such a pain to find premium once you leave the city

Where do you live that you can't find premium?
I've never had that issue....anywhere. Except AK which is 90 octane state wide only option.
