does anybody know if any of the gas stations in alaska sell gas with no ethanol? below is an excerpt of an article from amsnow explaining what the ethanol does to us 2 stroke snowmobilers... so if anybody knows which, if any in alaska, sells pure gas, be it premium or whatever... i live in wasilla, i'm going to do some asking around when i stop at gas stations see if they know anything, but if anybody else might have an idea of somewhere to get some good ol school gas that won't run as high of a risk of burning down, please lemme know, thanks in advance
"Unless youíre a serious horsepower junky with an engine built specifically to run on alcohol, this kind of fuel is very bad for your fuel system and engine. Ethanol, the form of alcohol widely blended into many grades of gasoline today, has qualities that can cause major headaches when used in your snowmobile engine.
First, itís an oxygenate, which means that it contains or draws in oxygen. This has the same effect on your engine as an air leak in your intake tract or seals, causing your engine to run considerably leaner.
Another bad quality, ethanol is hygroscopic, which means that it ingests water. The ethanol in your fuel will, by nature, draw moisture from the atmosphere. The longer it is exposed to air, the more it will ingest. Finally it will reach the point that the alcohol/water mixture becomes heavier than the gasoline that suspends it. This is where phase separation occurs. The mixture of alcohol and water drops out of suspension in the gas and becomes a blob of nasty crud in the bottom of your fuel tank, float bowl, or gas can.
Phase separation causes two problems. One is that blob that will find its way into your engine where it will wreak havoc, but the underlying problem can cause just as much trouble, or more. When phase separation occurs, the gasoline that is left behind loses its octane rating.
Ethanol has a higher resistance to self-ignition than gasoline. This resistance to self-ignition is the basis for your octane rating. The higher the number, the more a fuel will resist self-ignition. For example, if your blended fuel had a rating of 87 and you take away the octane benefits of the ethanol, your rating will drop considerably. If youíre already playing tight to the fence of your octane requirements, this could mean death for your engine.
Another negative, ethanol does not facilitate an oil mixture as well as gasoline, at least not for long. Ethanol, because it is vegetable based, does not blend well with petroleum. Over time your 2-stroke oil will separate from the alcohol just as the alcohol will separate from the gasoline. While it may not be quite as big of a deal for oil-injected engines, it can be vital in a premix situation. "
