Why is ethanol bad for your car?
One of the issues with ethanol is that it attracts water and it does break down faster than gasoline. This is not much of an issue with transportation vehicles. But with small engines this can be a huge problem. With water absorbing into the fuel, there is the chance that rust will form on the interior of the engine.
Does ethanol help or hurt gasoline?
To some extent, however, ethanol does succeed at diluting our petroleum-based gasoline to help stretch our supply. When the United States first embarked on this strategy, only a small percentage of ethanol was added to the mix -- generally, most engines didn't even notice and kept running as usual.
Is ethanol an acceptable fuel?
With few exceptions, ethanol is not an acceptable fuel on its own merits. To some extent, however, ethanol does succeed at diluting our petroleum-based gasoline to help stretch our supply.
What is the problem with ethanol fuel?
Ethanol is corrosive. Ethanol reacts naturally with oxygen in the air to form acidic compounds which lead to corrosion of fuel system components and engine wear. With the presence of both water and ethanol, corrosion is accelerated in all metal types.

Why is the E15 banned?
This seasonal restriction was aimed at reducing smog but it had an unintentional benefit for owners of gas-powered outdoor power equipment. Because the summer months are when the use of outdoor equipment and tools are at their highest, the ban helped to prevent us from absent-mindedly filling our tanks with too high of a concentration of ethanol mix.
What was the impact of the Energy Policy Act of 1992 on the American economy?
The Rise Of Ethanol In American Fuels. The Energy Policy Act of 1992 radically changed the landscape of alternative fuels and America’s dependence on foreign oil. State and local governments were compelled to implement initiatives to reach alternative fuel levels set by the federal government.
What are the problems with ethanol?
Other known issues include phase separation, vapor lock, corrosion, oxidation, and altering of the combustion and compression ratios.
What is ethanol?
Ethanol is the same type of alcohol that is found in an alcoholic drink. It's often used in motor vehicle gasoline as an additive. Our gasoline today contains roughly 10% ethanol, E10. With this fuel composition, it has close to the same amount of energy potential that straight gasoline does, only 2-3% less. And if you want to use ethanol fuel (E100), it takes 1.5 gallons of E100 to equal the same amount of energy given by 1 gallon of gasoline. So you ask why this would be so bad besides the increased cost of running a higher ethanol rated fuel? Why are people starting to use this gas more? Let's take a look at some of the bad and good about ethanol gasoline. We will talk about some general good news, bad news, and how ethanol effects small engines a little more specifically. I always like hearing the bad news first.
How much ethanol was produced in 2011?
So in 2011, with the total acreage of land used for corn puts the United States at a total of 23,845,600,000 gallons of ethanol in one year of 100% of all corn is put towards ethanol. If we changed over to E85 we could produce 27,422,440,000 gallons of E85 if there was no waste.
How many miles per gallon is E10 gas?
The New York Times stated that E10 gasoline, which is the gas we use in America, actually gives you 2-3 miles per gallon less than gasoline. E85 is a flex-fuel with 85% ethanol loses 7-8 miles per gallon.
How long does it take for E10 gas to break down?
The ethanol in E10 gas breaks down quickly. An MTD area representative informed me that E10 begins to break down within 3 weeks. This break down creates clumps in the gasoline mixture at some point and this may clog the filter, carburetor, fuel line, etc. To help prevent this a person should purchase a product such as Sta-bil and add it as directed to their gas. This will help prolong the life of the gas and keep it from harming your small engine as much. Talking with an area small engine repair shop, the E10 breaking down is the major cause of equipment being sent in. And after inspection, diagnosis, repair and testing it generally cost between $50.00 and $60.00 even when the issue is simply bad gas. They drain the system and add new gas that has a stabilizer in it after diagnosing the issue.
Why is Flex Fuel important?
And this increases the cost of food products, which creates competition for the ethanol fuel. Notice that this is the second time that I have mentioned this - it is important. And 328 gallons of ethanol can be created from 1 acre of land.
Why do we use ethanol over gasoline?
One of the political reasons for using ethanol over gasoline is to prevent America from heading into a greater mercy hold of foreign oil producing countries. Which is a good reason for a purely political nation.
How is ethanol made?
In the United States, ethanol is created from corn. The largest crop produced in the United States, roughly 72,700,000 acres of land go towards growing corn. During the time of writing this hub that is about $15,100,000,000 per year. Approximately 7% of the national corn yield went into making ethanol in 2001 and that increased to about 39% in 2010. And some of you may be wondering way.

Why are We Using Ethanol?
Initially, ethanol was added to cars back in 1979 to help reduce carbon monoxide emissions and comply with the government’s air-quality regulations. That’s great news, right? Who doesn’t love saving the planet?
Why is ethanol used in agriculture?
So, a large part of why we’re now using ethanol is to lower the cost of gas, and subsidize farmers. Corn has become a major stream of revenue for farmers, who would probably rather be growing food, but can’t seem to make ends meet by doing so. Therefore, we have an abundance of ethanol, and it has got to go somewhere.
How much ethanol was produced in 2014?
For one, the United States produced 14 billion gallons of ethanol in 2014, which is up 4 billion gallons since 2009. Which, wouldn’t be much of an issue, if not for the fact that our modern engines no longer require the use of ethanol to reach the government’s air-quality regulations.
Why does ethanol separate from gas?
And finally, when an ethanol/gasoline mixture sits stagnant in a gas tank for a long time, it can separate due to a process called phase separation. Phase separation, in short, happens when water finds its way into your gas tank and mixes with the ethanol.
Can ethanol cause problems?
But on the flip side, if you’re driving an older vehicle, the ethanol may be causing problems. Alcohol is a highly corrosive substance that’s hard on plastic, rubber, and even some metals, and over time it will eat away at your vehicle’s most vulnerable components. Additionally, alcohol in an old engine can start to dislodge the build-up of carbon deposits from inside the engine. That may sound like a good thing, but that buildup can actually move into places where it chokes the engine’s fuel supply.
Is ethanol a renewable fuel?
Ethanol is a shortened name for ethyl alcohol, which is a renewable (as long as we can grow crops) fuel source made from plant material. Ethanol is a clear, colorless liquid that in the United States we make almost exclusively from corn. It’s estimated by 2030, ethanol could replace up to 30% of U.S. gasoline demand.
Is ethanol good for cars?
Ethanol is not for every engine, but for some engines it’s a perfectly fine. Older vehicles are more susceptible to the problems caused by the ethanol/gas mixture (water in the gas tank, stagnant gas, rubber hoses, etc), so if you’re driving a classic, we recommend checking out this website for a complete list of gas stations with ethanol-free gasoline. But if you’re driving a vehicle built in the last 10 years, we say you’re good to go. Fill up with your recommended fuel octane, and don’t sweat it from there.
What is Ethanol?
Ethanol (CH 3 CH 2 OH) is flammable alcohol distilled from plants, chiefly corn. According to the Alternative Fuels Data Center, about 98% of gasoline sold in the US contains some amount of ethanol.
Can Old Cars Use Ethanol?
Generally, old cars should avoid ethanol gasoline as much as possible. However, the dose makes the poison, and low levels of ethanol usually don’t do an appreciable amount of damage. However, years of frequent ethanol use can wear out an old motor under the right circumstances.
