Because when the crop grows, it removes CO2 from the air, and is stored in the crop, released again when it is processed. Oil or coal in the ground is contains CO2 that was removed from the atmosphere and stored millions of years ago, and is now being released to the atmosphere.

Note my previous post said "excluding the oil used to do so."

 

We have no choice in our area,all fuels are 10% ethanol,no problems so far.My preference is Fitch Fuel Catalyst's in everything we own.

 

search www ethanol free gas for locations of stores in usa & canada
for pure gas. Everyone in my area thought "all" had ethanol but this site listed 6 locations in my city, 1 about 3 miles from me & my davidson, car & truck run & sound much better. Search ethanol for information. Good & bad.

 

We're way past the hijacking point on the OP's thread, but most carbon in crop plants comes from stored sources in the ground (technically humus)- nearly 100%. Most plants can get all carbon from co2 only but it takes then years if not decades to grow. Even scrub in the sahara uses humus as a primary source of carbon.

Burning eth is just like burning coal in that respect. Now if you could somehow pull co2 out of the air and root-feed it hydroponically then it would be closer to neutral. Provided of course you used no co2 releasing energy to do so.

Now probably time we stopped because this thread is about whether or not e10 will hurt a bike.

 

This would be fine for bar hopp'n, or a point A to point B ride with a non-ethanol stop in between. A cross country type trip with no internet would not work. So far I have had no problems with 10%, but 15%, who knows.

 

Not trying to be a pain in the a**, but here in the US we have the world's most advanced technology in 650 HP alcohol-burning auto engines. When optimized for ethanol, 40% of the BTUs in a gallon of ethanol can be used to turn a wheel. When optimized for gasoline, 25% of the BTUs in a gallon of gasoline can be used to turn a wheel. Your bi-combustible cars get better mileage with gas because of the compression limitations of any engine that burns gasoline. It is a "compromise engine", designed to run both fuels. It is NOT optimized to run alcohol, because it would be unable to run gasoline. The knocking of the gas fuel in the alcohol-optimized engine would damage the engine permanently, and quickly. Cars with engines optimized for gasoline will NEVER have better mileage than engines optimized for alcohol, the reason is that alcohol will burn more efficiently, period. The only way this would be the opposite is if you could change the laws of physics, which of course you cannot - at least not on this planet.

 

With all due respect to what you think you know, you are in error, and I can't leave this thread without a final reply.

Google Carbon Cycle. Humus, by the way, is plant and animal material decaying in the soil, releasing its stored carbon which was obtained from the air in the growing cycle, or, in the case of animals, from eating the plants.

I work for one of the largest ethanol producers in the world. That doesn't make me a fanatic about it, I'm just informed as to fact vs fiction concerning something that affects me on a daily basis, whether it's fueling my Harley or earning a paycheck.

I think I was probably in third grade or so when we were taught this:

"Photosynthesis. Carbon exists in the atmosphere as the compound carbon dioxide. It first enters the ecological food web (the connected network of producers and consumers) when photosynthetic organisms, such as plants and certain algae, absorb carbon dioxide through tiny pores in their leaves. The plants then "fix" or capture the carbon dioxide and are able to convert it into simple sugars like glucose through the biochemical process known as photosynthesis. Plants store and use this sugar to grow and to reproduce. Thus, by their very nature as makers of their own food, plants remove carbon dioxide from the atmosphere."

My apologies to the OP for the distraction in this thread.

 

This, I think explains it all , LOL!

I too, apologize to the OP!
