Alcohol burns hotter than gas and due to the sugars in alcohol the more you burn the more likely it is to burn a hole in the piston, but that takes a pretty neat alcohol.. also alcohol is hydroscopic, it holds water.. but the other thing about ethanol is that if left in the carbs over winter it can form a varnish like residue which can harden on the rubber parts and also block the jets..

The idea being the alcohol added will soak up any moisture in the gas and prevent it from freezing - eventually burning and removing the moisture from the fuel system. So assuming gas pump alcohol is water free (and that's probably a wrong assumption) then it might help removing water from your gas.
I know that one problem with alcohol's water absorbing ability is at some point it can absorb too much water (super saturated) after which some sort of a shock (including mechanical shock or maybe a temperate change) can cause phase separation and the water will precipitate back out of the alcohol (at least back to some saturation level).

- February 19, 2015, 22:31:44 PMAs I understand it, much of the concern regarding corrosion is the fact that alcohol attracts moisture. As we all know moisture in gas is a problem. Adding even 15% corn-ohol will attract as much as 30% more moisture to the mix. That combined with the fact that some rubber and plastic compounds do not fair well with alcohol to begin with adds up to bad news for a system not designed to deal with the mixture.

My bad... I got in a hurry and typed without thinking - I was reading "E15" but thinking "E85" in my head.....
My take is that even 15% ethanol isn't great for older cars not designed for alcohol - but I don't think it's as bad as it is for bikes and other smaller engines. Besides the corrosion issues, alcohol burns leaner (and hotter) than gasoline, which is more of a problem with bikes and other smaller engines which don't have the elaborate feedback system to automatically adjust the fuel mixture. Cars have a lot better system to adjust the fuel mixture to compensate for the alcohol. A carbed bike does not.

But, it's OK for a car or truck to get a "hose full" because it would be diluted with the rest of the fuel, say 10-20 gallons.

- February 19, 2015, 16:42:43 PMQuote from: Bucko on February 18, 2015, 00:02:15 AMAccording to the article, the exemption for motorcycles appears to be based on the notion that since a motorcycle's tank is typically small, a preloaded hose full of E15 could 'pollute' a fill up of regular gas. But the articles doesn't adequately explain why a small amount (a hose full) of E15 is bad for a motorcycle (apparently bad enough for an exemption) but 'OK' for a car filling up with a full tank of E15?

- February 18, 2015, 08:39:15 AMIt is possible that E15 will not catch on because the price of oil has been reduced significantly. The cost to produce ethanol, even with govt. subsidies is prohibitive in the current marketplace.

- February 17, 2015, 22:37:17 PMHere's an article about EN15 waivers for motorcycles. The article is a couple years old but it talks to the issues and the problems with non flex-fuel vehicles. According to this motorcycle are exempt. (for now) Of course that's OK providing you still have the choice not to buy EN15 gas. Those day may be numbered.

- February 17, 2015, 21:45:58 PMNothing confusing in that, it seems that it has already started, the governments have drawn a line in the sand, from 2015 all vehicles will be made to run on E15, anything older than that will take years to suffer real damage, most will no longer have carbs, they will run on FI and their manufacturers guarantees will have expired, and insurance companies will start charging extra for non ethanol vehicles, and I think it's just smoke and mirrors about the big oil companies fighting against this because (a) the big oil companies will still supply 85% of each gallon and (b) they will already have invested heavily in ethanol production facilities.

- February 17, 2015, 18:06:05 PMI live in the Southeaster Wisconsin Emission Control Area. Basically my county requires emission checks on all cars. (so far not bikes) We have up to 10% ethanol in our gas (special formulated gas). The county line is three blocks west of my house. The next county is outside the emission zone. (Funny, the air does not smell any better) Fortunately I can head west when I need gas and fill up outside the ethanol zone otherwise I would have to put "corn-ahol" gas in my bike. No sure how it would run. Not sure I want to find out.

- February 17, 2015, 11:01:01 AMThis is probably a sign of things to come..
First the government will start a positive campaign to promote the environmental issues and say how good it is for global warming, and then after a few years you will not be able to find non ethanol fuel at all, give the manufacturers a few years to discover grants available for promoting E5,10 and 15 and in about 10 years time they will stop publishing the amount of ethanol in the fuel at the pumps, the next step will be only E15 is available..
In Britain we have a take it or leave it policy and most pumps no longer say if there is ethanol in the fuel.. We can either take what they sell or not ride/drive.
When the government wanted us to use diesel in cars they sold it at the pumps for just under half the price of petrol, three years further on, after most of the cars on British roads had converted to diesel and the price had more than doubled so it now costs more than petrol.

The state of Georgia has become the 16th state to offer E15 fuel for use in all flex-fuel vehicles. The other U.S. states where the higher-level E15 blend is available are Kansas, Nebraska, South Dakota, North Dakota, Minnesota, Wisconsin, Iowa, Tennessee, Alabama, North Carolina, Michigan, Florida, Ohio, Illinois, and Arkansas.
BE VERY CAREFUL not to put this into your bike. Also, be aware you can get a bunch of it if you use a pump with a single hose and multiple grades of fuel. This stuff is very bad for bike motors.
