Why is it illegal to run a car on 100% ethanol?

Question

Is it dangerous or just because the oil tycoons are running the country?

Answer 1

we used to

we will again

it doesn't matter how much it costs to produce the cars or the ethenol, the point is that it is renewable.  I don't care that ethenol is 30% less efficient than petroleum, yknow why?  Cause I can grow more ethenol  !  If we stopped growing poppies over in the middle east and started growing CORN, then they wouldn't starve.  I have no symp[athy for someone who complains their hand is bleeding when they continue to stab it with an ice pick.  They answer is in front of us but we don't like change.  If you don't want to change quit complaining!  The argument that poeple are starving because we want to use crops for fuel is STUPID... GROW MORE FOOD NOW!  How can we complain ethenol MIGHT take food from the hungry when we don't grow food to feed the hungry now?

Answer 2

I think it is quite dangerous.Why use ethanol?Water can now be used & even much safer than ever! Refer to the URL & scientific videos in it & it'll get u converted in no time!

It even does not void the warranty coz it's reversible!Take a look!One day all the cars will use these.CNG,eat your heart out.

Answer 3

There is not a law against running a car on 100% ethanol. The cars just do not like it.  Ethanol has a very high octane of about 121 compared to regular grade gasoline's 87. That means that ethanol does not burn as fast as gasoline, which is good for high performance but bad for cold starting.

The cold start problem is cured by adding 15% gasoline to the ethanol hence the E85 blend. It is not a state or federal law but a law of physics that prevents running 100% ethonal in cars.

Answer 4

There is no law against it.  In fact it makes things easier.  Vehicles that run on pure ethanol don't have to have the ethanol as pure.  You can distill it to only 70% to run it.  Meaning it can contain 30% water.  When you mix it with Gasoline it must be 100% pure because gas and water don't mix.  But I believe when you add gas to it, the water falls to the bottom so you should be able to drain it out 1st to get rid of the water.

Answer 5

i don't think it illegal, you just simply can not run it!

Answer 6

There is no law against using E100.  It is perfectly legal to burn 100% ethanol in your car, if your car can use it (and even if it can't).  If you are producing your own motor fuel, there will be tax issues.  Motor fuel doesn't just have sales tax, but also a motor fuels tax, which pays for the road ways.  Anyone using motor fuel is required to pay it.

You'll only find engines designed for 100% ethanol in some racing leagues.  There are no passenger cars that can use E100.  

Some research has suggested that normal cars gain optimum benefit from using somewhere between E20 and E30.  It also suggests that most cars can use up to E65 without problems (but why, if the optimum is E25?).  FlexFuel vehicles can use anywhere from straight gasoline to E85.

Answer 7

1 TANK OF ETHANOL WASTES ENOUGH FOOD TO FEED A STARVING PERSON FOR A YEAR!! ONE TANK!!!

2 IT ALSO PRODUCES MORE WASTE THAN REGULAR GAS!

American grocery stores are starting to introduce food rationing. Wal Mart is restricting the amount of rice customers can buy. In Mexico and Yemen, in Egypt and Indonesia, the poor are taking to the streets to protest massive rise in food prices as well as shortages. A short distance from our shores, the troubled nation of Haiti is in crisis again; Haitians, dependent on U.S. grain imports, have seen those dry up and have been reduced to eating cakes of dirt.

How did this come about? Because on top of rises in energy prices and some changes in the diets of developing world countries, we are burning a large portion of the world's food crop in our cars’ fuel tanks, in the name of reducing greenhouse gas emissions and curing our "addiction to oil."

Answer 8

It's not illegal. It is just inefficient and dangerous to whino's!

Answer 9

There are no cars made to run on 100%.

But if there were, and we sold 100% ethanol at the pump, would people just take it for beverage alcohol?  That is what happened when we had 100% ethanol being used as antifreeze. ( That was the case when I was a baby.)
