Here in Utah, beginning this month (or so), most gas stations are now selling gas with 10% ethanol. I guess I am always the last to notice things, but apparently this is being mandated by the feds, basically saying some percentage of gas sold must contain ethanol.

I personally choose not to use this gas, if possible, so I have been looking around for stations without it. Disregarding the emotional, ecological considertions, etc., I am simply wondering if some prefer to buy ethanol fuel, or not. And do you make any effort to find a station which sells your preference?

There is no technical reason not to. All modern cars are designed to run on E10.

What I would like is a factory turbo that can take advantage of E85. Ethanol is a superior performance fuel to regular unleaded gas--it has a way higher effective octane rating (~105). You need a beefier fuel injection system (pump and injectors) to make up for the lower fuel density, but you can run a lot more boost, ignition advance and/or compression. Race gas at the Kroger on the corner!

 

i think mau has had some issues with ethanol mixed gasoline during winter. i play it safe and try as much as i can to fuel up with shell 91 vpower (0% ethanol here - keeping fingers crossed). sometimes i end up with sunoco 94 (10% ethanol) but only in "desperate" times when it's already below 1/4th tank LOL

 

where are you guys even seeing gas w/o ethanol. I have not filled my car up once, w/o ethanol additive in a few years. ???????

ethanol is a joke, btw. completely inefficient and a waste of our resources in the US, for what it takes to derive ethanol for commercial use, there should be investments made in other alternative fuels, if we stick on the fuel route...to reduce our consumption of overseas oil, our govt created the idea, rather bush, to pump up ethanol, a completely idiotic investment because the process could not be more dissimilar to countries like Brazil, that derive fuel from pure sugar cane in an efficient & sustaining process. Altho climate/ecology differences exist, ethanol is not and should not be the way for our country. Additionally, yes its combustion rate is greater, but its efficiency is almost 5-10% less (=less MPG). I, for one, do not support ethanol in this country. but its not like we have a choice at the pump, at least not where ive been filling up. not sure about the rest of the country. Corn based ethanol is not the answer.

 

Not saying I disagree with the policy part, but efficiency measured miles per gallon is irrelevant. What matters is
miles per dollar. (Which ties right into your policy comment: Ethanol is so heavily subsidized its actual cost to consumers is much higher than its pump costs.) If E85 was readily available, and I knew its price would be stable at 50% of premium gas, I would consider getting the RDX tuned for E85.

 

we still have it here in the great white north hopefully this doesnt change...

 

I'm still waiting for my Mr. Fusion to power my car for the last 20 years!!!
