EPA OKs 15% ethanol (SEMA) opposes the shift from E10 to E15 due to concerns that the additional content will harm automobiles of all ages, including special interest collector and historic vehicles.

Ethanol used as gasoline is not cost effective.

The Green lobbyists are against all oil producing corporations and are pushing ethanol.

Ethanol costs more per gallon to manufacture and has less BTU output than a gallon of oil when it burns.
Gasoline has 116,090 BTU's per gallon output. Ethanol has about 76,330 BTU's per gallon output and it takes about 25,000 BTU's with today's technology to make a gallon of ethanol.


Ethanol has 35% less energy (BTUs) than gasoline.

Simply said, you will burn 35% more fuel using ethanol to provide the same energy output.


Fuel ....................BTU/lb .................BTU/gallon
Gasoline ...............18676 ..................116090
#2 diesel ..............18394 ..................129050
Ethanol .................11585 ...................76330
Propane ................19900 ...................84500
Methane ................20263 ...................19800
Hydrogen ...............52217 .....................N/A

The move to E-15 is political to provide subsidies for the grain farmers.

Burning E-15 will:

(1) cost the United States a 3% loss in fuel mileage

(2) it will cost more money per gallon at the pump for the consumer and

(3) it will be more corrosive to plastic and rubber parts in pre 2003 automobiles with factory fuel systems.

What will happen if the government ends or reduces the farm subsidy being paid to corn growers to offset the production costs of ethanol? The price for ethanol may skyrocket and all the E-15 flex fuel programs required by the government will be an economic drain for consumers adding to the recession.

The consumer bears the cost of adding ethanol within the price at the pump of paying for ethanol blends without any discount over straight gasoline. The government has been discussing a mileage tax on all vehicles to make up for projected shortfalls in the taxes collected from the sale of gasoline. This helps offset drivers of electric cars who pay high rates for electricity.

Oil will be here for a while. If you don't like it buy a overpriced, modestly optioned, undersized, Chevrolet Volt for $43,000 and make a statement that you believe in global warming.

The BTU content of gasoline, propane, methane, hydrogen or ethanol as a fuel may be found at the Department of Energy website.
However there are other sources more user friendly such as
[You must be registered and logged in to see this link.]

The methodology for determining the BTU's to produce a gallon of Ethanol is the amount of energy to refine it. In order to heat the composted grain mash to boil to distill 95% ethanol as a by-product. They did not consider the farmer's tractor, fertilizer, transporting the grain, that is extra energy and cost.

It takes more energy to produce a gallon of 100% ethanol than that gallon of ethanol as a fuel can return as BTUs.

However what the oil companies put in gasoline in your car is 95% ethanol. The extra 5% is water which is an azeotrope. Yes, I said that there is 5% water in the ethanol.

For every gallon of E-15 you add to your tank, you are adding 1.0 oz of water or one shot glass.
For a 16 gallon tank, you are adding 16.0 oz of water to the tank, or two pints of water.

Now what do you think that two pints of water will eventually do to a 30 year old gas tank?

So in a gallon of E-15 gasoline that you put in your classic Firebird, this is what you are adding to the fuel tank.

gasoline..................108.7 oz
ethanol....................18.3 oz
water.......................1.0 oz

total........................128.0 oz
