Ethanol vs. Non Ethanol fuel?

[aebsledder]

Simple question. Is the gas station required to inform the consumer if its fuel contains ethanol or not? My new sled has two fuel maps and if I run it in ethanol mode with non-ethanol fuel the owners manual claims engine damage could occur. Sounds like a lot of people are running theirs in ethanol mode, but I can't ever remember seeing fuel around here (bozeman) containing ethanol.
Thanks

Here in Missoula/hippyville the pumps have a label on them that tells you the dates when the regular pump fuel is oxygenated with ethonal/winter blend (November to March if I'm not mistaken but I probably am). Some of the stations around also have pumps with non-oxygenated/non ethanol "snowmobile gas" that's 91 ocatane and costs a little more. Do not run ethanol with your sled set for non-ethanol gas because it will advance the timing and detonate and you'll have a nice hole in your pistons after a while.

I always run 91 Octane here, I don't ever recall seeing an ethanol label on any of the grades of gas.

Yeah, I don't know about other places, but here we have 91 "winter blend" and 91 "snowmobile gas". Running 91 winter blend is like running 88 regular non-ethanol blended.

i think by law if its more than 8% ethanol it has to have a little sticker on the pump. in north and south dakota they all have little square stickers on them.

If you want to see how bad this fuel is find yourself a mercury outboard dealer. Ask them for the service bullitin on fuel and read about it.
