You got that right. The chain of Gas City gas stations in my area sell E85 for 10 cents less per gallon than regular gas. You would have to be crazy to buy it. You save 4% on the cost of the fuel but use 25% more fuel. Whose brilliant idea was that anyway.

Actually these is some talk of increasing the ethanol content of gasoline to 15%. Archer Daniels Midland is lobbying very heavily to get this passed. I guarantee you at 15% levels there are going to be major problems. Much more than at 10%.

Yes ;i saw a tachnical show here they tested and loked at flex-fuel vehciles and one of the tings they found as a unusaul amount of carbon buildup. That can be celaned but takes more mainteance. There is alos less product produced from a barel fo crude when using enthnol as a aditve instaed of others.Overall its all a politcal thing and can be much expanded becuase of the corrision problem an dhte exp[ense of trucking it which comsume more fuel.That is probaly why the producers are wanting more per centage because its heavily subsidesed and requires alot of energy to prodcue. Its not a winning situation except for the producers really.

"Straight" regular gasoline is usually refined as 86 octane, because when it is blended with 10% ethanol, the resulting blend is 87% octane. (Ethanol has a high octane rating.) The blending is done at the dealer, just before he ships it to the retailers. I guess in this case the dealer decided to ship the unblended 86 octane as well.

There is one station in my area where I can still get "the real thing." The air base used to have it too, but they recently turned coat and sell only the junk now.
I pay at least 30 cents a gallon extra for it, but it balances out in better MPG.

Ethanol does reduce the energy content of gasoline but has a high octane rating so you probably won't notice much difference except a slight decrease of mileage. Octane ratings will vary from state to state with 93 being closest to the old leaded 'premium' but 91 is usually adequate.

I feel my car runs best on straight gasoline but I can't buy it here.
Michigan seems to have God's Gas. I think Ohio does also.

Anybody know where I can get plain regular gas with no hooch within a reasonable drive from Central Washington? Anybody? Buehler?

I have a motorcycle and the manual says not to use over 5% ethanol. Does premium gas have less than regular? Also, I live near Tampa does anyone know where I can get non ethanol? Thanks , Tony A.

They didn't fail to design the fuel rail in any way, it's just that the rest of the world knows better than to mix Ethanol into all available fuel types.

First thing I noticed when filling up a car here in the states was that the gas smelled... well, bad.

I'm used to 95 Octane (though I'll se 93 every now and then, but god knows who buys that.) being the lowest rating with Shell making a 99 Octane blend, being the highest.

Is there anywhere in the Dallas area you can get at least 95, but pref 98 Octane from a pump? Or would I have to buy race fuel and mix it in?

I'm always intrigued by these ethanol debates. There is such a wide disparity of strongly held opinions.


Several years ago, when we still lived in Minnesota, several local gas stations sold E85. I don't know whether it was mandated, or just a local thing, but E85 was always exactly 50 cents per gallon cheaper than regular. At the time, regular gas was $1.50 per gallon, so E85 was $1.00. Any chance I got, I'd fill my '97 VW Golf with E85. My mileage would always drop from 31 mpg to 26 mpg when running E85 - a 17% reduction. I could not discern any change in performance, and I never had any problems running E85, so it was very much worth it. However, I do not now run E85 because it's only a couple cents per gallon cheaper, and not worth it.

I'm also puzzled by the claims of drastic drops in mileage, while running ethanol blend gas. I have a cousin who drives a late-90s Ford F250 4x4. He claims he gets 13 mpg running regular gas, but drops to 10 mpg when he runs ethanol blend. I have no reason to doubt his word, but I have never had that kind of mileage difference when running ethanol blend. Dodge Caravan, VW Golf, Ford Focus. No discernible difference for any of them.

I've also never had any ethanol-related performance or mechanical problems with any of my vehicles.


I know that this is all anecdotal and personal experience related. Even so, the whole debate just puzzles me.

It's worth noting that we calculate octane differently here. Most of the rest of the world just labels it with the research octane number (RON). Here in the U.S. we calculate octane by adding the research octane number plus the motor octane number, then divide the result by two [(RON+MON)/2]. A rough guide is to take the U.S. octane rating and add 4 to obtain the number used in the rest of the world. So what you call 95 octane, we actually call 91 octane. In the U.S. the highest octane usually on offer is anywhere from 91 (or 95 as you'd call it) to 93 octane (or 97 as you'd call it) depending on your geographic location. If you feel the highest available in your area is inadequate, a cheap and easy way to boost your octane is to add a bit of toluene.
