Ethanol - Non ethanol question

[Bigrock33]

If I am using 91 ethanol and the ethanol plug, and I have non ethanol 92 in my spare gas can (for longer shelf life), can I use the non ethanol without changing the plug? Any down side? Potential problems?

The only problem is running ethanol fuel with the non-ethanol plug. Doesn't hurt to run non-ethanol fuel with ethanol plug

Having the plug on the "ethanol" side should only increase your fuel curve by 5% (if memory serves me correct).

The downside would be no performance gain. Using non-ethanol gas with the non-ethanol plug will lean out the fuel increasing performance. what would be bad would be to run the non-ethanol plug with ethanol fuel.

If you are riding high enough in Utah, you might find that you can ride with ethanol fuel and use your non-ethanol plug. Here in Colorado I have rode for two years with the non-ethanol plug using pump gas 91 ethanol fuel. We ride 9k-12k.

Thanks for the replies fellas. Figured the best way to keep the spare gas "fresh" for as long as possible would be to get the 92 non ethanol. The gas is actually quite a ways away from me but have a friend that drives by there for jobs about every 2 - 3 weeks, so bringing back enough for a couple spare gas cans would be easy for him. If there is still gas in the spare cans then use it about every three weeks and replace with fresh, should be better than keeping ethanol for 3 weeks. Don't really want to throw spare ethanol in the sled every time it is used and then have to fill up the spare cans all the time.
