Ethanol setting means a richer fuel mixture. I think that EPA mandates require sleds to run too lean, particularly, at the mid-range power/rpm settings. I use ethanol regardless of fuel type to be safe and if you have an aftermarket can, then ethanol with regular fuel would work best. If not, put 20-30 hours on engine before switching to non-ethanol with non-ethanol fuel to get maximum performance from engine.

Thanks, that makes sense. I thought it would be harmful in Ethanol setting using non eth gas.

 

[Drewd]

Nope, not harmful at all by running the engine slightly richer.

Not meaning to hijack this thread, but a thought crossed my mind. I can understand that the ethanol setting richens the fuel, but it doesnt richen the oil. SO everyone knows these polaris pro's drink very little oil, but by richening up the fuel say 2-5% we are actually diluting the oil mixture...???... Maybe my thought process is off today, just like yesterday, and the day before.... Anyone have an idea on this?

 

[trestlecreek]

After thinking about this, maybe the ethanol setting doesnt add more fuel, but retards the timing.... therefore not diluting the oil mixture rate......

If you have a Pro, you should have turned up your oil pump 2-3 turns from stock anyway!
