If you know anything about ethanol, you know it sucks.
If you don't know, read this, and grow a brain.

Worries over ethanol
The American Motorcyclist Assn. is expressing concerns over ethanol's effect on motorcycle engines. Federal regulations currently cap the percentage of ethanol in gasoline at 10%, but Minnesota is asking the U.S. Environmental Protection Agency to allow double that amount in its fuel. The motorcyclist group fears that an EPA waiver would prompt other states to follow suit.
The problem with increased ethanol levels is that motorcycle engines are certified to run with only a 10% ethanol blend, the association stated in a July 3 news release. Ethanol burns hotter than conventional gasoline, so it runs the risk of damaging air-cooled motorcycle engines. It may also corrode fuel systems.
"The AMA supports the use of cleaner-burning fuels, but we are concerned about premature engine damage or failure while a bike is being ridden on a highway if the allowable level of ethanol is raised to 20%," said Imre Szauter, the group's legislative affairs specialist. "We are also concerned about any degradation in performance, fuel economy and rideability that may result from the long-term use of blended fuels with greater than 10% ethanol.
"Until studies show that a 20% ethanol blend won't damage motorcycle or ATV engines, and won't make motorcycles emit more nitrogen oxides than are allowed by the EPA, the AMA can't support the Minnesota proposal."
Among classes of additives, which include antiknocks, corrosion inhibitors and antioxidants, performance additives are expected to experience the greatest growth in the coming decade. Performance additives include detergents, dispersants, anti-icers, combustion enhancers/modifiers, fluidizer oils and flow improvers. All these additives improve either fuel or engine efficiency or durability
Some corrosion inhibitors are hexamine, phenylenediamine, dimethylethanolamine, sodium nitrite, cinnamaldehyde, condensation products of aldehydes and amines (imines), chromates, nitrites, phosphates, hydrazine, ascorbic acid, and others. The suitability of any given chemical for a task in hand depends on many factors, from the material of the system they have to act in, to the nature of the substances they are added into and their operating temperature.
An example of an anodic inhibitor is chromate which forms a passivation layer on aluminium and steel surfaces which prevents the oxidation of the metal. Sadly chromate is carcinogenic in humans; the toxicity of chromates was featured eg. in the film Erin Brockovich. Like hydrazine, the use of chromate to protect metal surfaces has been limited, for instance it is banned from some products.
Nitrite is another anodic inhibitor. If anodic inhibitors are used at too low concentration, they can actually aggravate pitting corrosion, as they form a nonuniform layer with local anodes.
An example of a cathodic inhibitor is zinc oxide, which retards the corrosion by inhibiting the reduction of water to hydrogen gas. As every oxidation requires a reduction to occur at the same time it slows the oxidation of the metal. As an alternative to the reduction of water to form hydrogen, oxygen or nitrate can be reduced. If oxidants such as oxygen are excluded, the rate of the corrosion can be controlled by the rate of water reduction; this is the case in a closed recirculating domestic central heating system, where the water in the radiators soon becomes anaerobic. This is a very different situation to the corrosion in a car door where the water is aerobic. For instance, cars suffer from the fact that water can enter the cavity inside the door and become trapped there. The fact that the oxygen concentration is not uniform within the layer of water in the door then creates a differental aeration cell leading to corrosion. A cathodic inhibitor would be of li

RE: Best gas stations
After much reading...
Chevron, Texaco, and in general the most expensive gas has less ethanol, and more actual oil based gasoline.
Racetrack is cheap to entice you to try it...not because it's cheaper to make, it's actually not, or better, it sucks.
So...
Most expensive per gallon...highest Octane with the lowest product letter...like Premium G is better than Premium Z.
Zinc Oxide...may be the simple anti-matter for ethanol. btw....
