Definitely get it! Like said Ethanol is basically corn/vegetable oil extract that is a filler in gas now-a-days.

Not extract, it's a distilate.

You get better mileage, for one. It also doesn't gunk up your injectors and trash your engine as fast as ethanol will. Think of sticky corn syrup residue in your engine... At least that's how I personally look at it. I go out of my way for No-E fuel.

Being a distilate, just like gasoline, it has none of the solids from it's source. Not even all ethanol is made from corn, it is distilled from many sources that contain sugars or cellulose.

According to "howstuff works.com", Shells ad campaign for this coincided with their suspending research into alternative fuels. Feel free to do your own research and see if you agree.

Nitrogen is an inert gas. Not even a nobel gas. I think it is more of a play on words in advertising for the uninformed general puplic to buy into. I'm sure all gasoline has a trace of nitrogen from being processed. Shell decided it sounded like a good story. If i'm wrong, show me.http://auto.howstuffworks.com/fuel-e...d-gasoline.htm

The best? According to Shell maybe. All gasoline is made to strict federal standards and then regional standards which explains the higher cost in California, it needs to burn cleaner by their states EPA standards therefore requiring additional refining steps.
Go to a refinery sometime, follow a few of the trucks that come out with a hazmat placard on it that has #"1203" on it. That's the DOT hazmat code for gasoline. See where that truck dumps his gas. It might not be at a station that is painted on the truck, or better yet follow a truck that doesn't have a name brand on the tank or door. It may just go to your favorite Shell station. When stations buy gas to put in their tank and pump to you, they don't need to be brand loyal. Especially if it is a long distance to the nearest refinery with their name on it. Over the years, I've seen Chevron trucks loading at Texaco refineries before they ever thought to merge. Shell trucks filling at BP refineries. Any combination you can think of, it happens. They add the name brand additives when they fill their truck at the refinery or terminal.
I am sitting in one of the largest refineries in the US as I type this. I spent most of last year in the largest refinery in the US.

Ethanol actually burns slower than gasoline therefore boosting the octane from it's starting point resulting in whatever octane is advertised at the pump. Higher octane burns slower allowing more advanced engine timing, reducing knock and increasing power by virtue of advanced timing. It's not just Calli gas, many states have 91 for premium rather than 93. I think it has to do with the regional climates and how the EPA standards are set up in theat region.
BTW, Chevrolet recommends minimum 91 octane, not 93 in the SS. It won't affect your ECM negatively.
