Ethanol in gasoline...how does it affect?
 

I'm seing more and more gas stations around here switching to at least a 10% blend, it is hard to find a gas station that sells it without ethanol. Will this affect anything since it burns hotter? I'm suprized I havent seen a thread about this yet, I was just wondering if your AFR's are any different with ethanol in the gas?

Everyone has 10 % here. I hope it doesnt affect anything? :-X

All I've heard (from a different site) is that it lowers your MPG substantially.

That can't be right. What environmental benefit would there be to put an oxygenate in gas that causes you to burn more gas from point A to point B?

it is right. ethonol has less energy per volume than gasoline.

1 Gallon of Gasoline = 125,000 Btu
1 Gallon of Ethanol = 77,000 btu

10% ethanol 90% gasoline blend sits around 100,000 btu's

Biodiesel is more benificial than ethanol as it sits in the 120,000-140,000 btu range. Ethanol is just for farmers trying to make money on their crops.

Eww that explains the mileage hit I took recently. BAck to getting my gas from jersey I guess. :S

I read on a Mustang forum (turbomustangs.com?) that Ethanol has a much higher octane rating than regular fuel, but contains less energy as previously stated. There was also something to the effect of it eats away at steel or aluminum so in order to use the pure Ethanol fuel you have to have your car converted for it.

From the sounds of what they were saying they mostly just change fittings and hoses and ---- to materials that are Ethanol friendly.

As long as the prices are lower for the pure Ethanol fuel I could see it becoming very popular, especially since they said the octane rating on it was like 100+ IIRC. Correct me if I'm wrong here.

Re: Ethanol in gasoline...how does it affect?
 

thats true. but more octane doesn't nessicairly equate to more power potential. More resistant to pre-ignition yes. But its also sitting around half the power of normal gasoline. So its going to take alot more fuel to get to the same power level as gasoline. I dont really see a benifit in it. Other than it being the oil comapnys soltion to the coke dealers creatine.

thats why cars love alcohol injection.. helps detonation... :P just dont use it daily..
