I buy all my Shell gas in North Attleboro, MA. 93 Octane was $4.09/gal last Saturday before the Stop & Shop discount they now accept. It's about 4 miles from where I live in RI and is about 16 cents a gallon cheaper than the Shell station close to me in RI.

I ALWAYS use 93 octane SHELL.....it's GREAT!!! In my Yukon I use 93 (top shelf) from Walmart.....it contains 10% Ethanol......that's reason I do NOT use it in my Z06. I used it once, and she did NOT like it. I could tell the power loss as well. I cannot tell difference in Yukon.Tim

No, and I googled it and couldn't find it. The station that ran the story was the ABC affiliate in Sarasota, Fla. so I was gonna go through their website. It was on at 11 p.m. last night.
What I took away from the report was that I will not feel uncomfortable putting Exxon in my car. I mean the two were very close. And they were, by far, head and shoulders above everyone else.
So I wouldn't hesitate to put Exxon in my 06.
I am a Shell user but that happens to be the closest station to my house and it's the most expensive around because of the neighborhood - a lot of fancy lawyer-doctor types, of which I am not one, unfortunately.

Growing a food crop for fuel - that's real smart - NOT!
Some studies show that ethanol takes 30% more energy to produce than the ethanol contains. For instance, a study at Berkeley (Natural Resources Research, Vol. 14:1, 65-76), on the energy input-yield ratios of producing ethanol from corn, switch grass, and wood biomass, as well as for producing biodiesel from soybean and sunflower plants, concluded that corn ethanol requires 29% more fossil energy than the fuel produced; switch grass requires 45 percent more fossil energy than the fuel produced; and wood biomass requires 57 percent more fossil energy than the fuel produced.
In 1997, the U.S. GAO found that the ethanol production process produces more nitrous oxide and other powerful greenhouse gases than does gasoline production. A decade later, Colorado scientists Jan Kreider and Peter Curtiss concluded that carbon dioxide emissions in the production cycle are about 50 percent higher for ethanol than for traditional fossil fuels.” [Source, Ethanol: Unintended Consequences]
It takes 1,700 gallons of water to produce one gallon of ethanol according to a Wall Street Journal report of a Cornell study. A study from Virginia Polytechnic Institute found that “the most water-efficient energy sources are natural gas and synthetic fuels produced by coal gasification. The least water-efficient energy sources are fuel ethanol and biodiesel.” Corn ethanol, produced in any quantity to make a difference in oil imports, will take massive amounts of land, destroy habitat and forests, and threaten our food supply
Finally, consider the rank stupidity of turning needed food production into fuel. Acres and acres of corn devoted to ethanol - driving up food prices - especially hard on the poor of this country. Unconscionable!
But to employ a process that actually requires more fuel to produce than it saves and that emits more toxins than the original process seems crazy.

(3) Stop loaning vast amounts of money to large banks at 0%, who are ( through spronsering hedge funds ), dumping that money into commodity futures.
But (1) is the big problem. Back in the 90s, there were limits on energy commodity futures for everyone not in the refining, energy or transportation business. And all positions were public knowledge. Bush #1 changed the rules under heavy pressure from Wall Street, and you can guess what has happened to energy futures since then.
Obama could, with the sweep of his hand, drive gas back to 2$ a gallon by re-instituting those rules. Its in his authority.

If this is true - and those sound like pretty reliable sources to me (Berkeley, Va. Tech and the GAO) - why on earth are we doing this? Is to help out farmers? If that's it, then OK, I can buy it.

We currently pay corn farmers not to grow corn so the price does not drop through the floor. The idea is, why not just pay them to grow corn for ethanol instead.
Almost every anti-ethanol person knows this, they just would rather make themselves appear smart by bashing an idea that *might* work. Im not saying it will, but we need to start getting off oil at some point. Im sure you work with people like that, no ideas of their own but love to criticize others for theirs.

As for the price of fuel, ITS CHEAP! People spend a dollar for a pint of bottled water and $4.00 for a gallon of milk!

Shell premium although I am not above going with what is available when I desperately need a fill up. Run Shell in my Goldwing as well and notice a clear difference in gas choices when I change from Shell to others. If the 1800cc bike senses the difference, I'm sure the C6 does too.

From: The Great Pacific Northwest...........I carry a gun cause a cops too heavy.
I avoid ethanol when possible for the following reasons.
Ethanol yields 75-85k BTU's per gallon
conventional gasoline yields 108-117k BTU's per gallon
Its terrible s"@*.

Take this little test: Pick a circuit (coupla hundred miles) that you can repeat identically, Fill with your "BJ" gas, drive the circuit, then go directly back to the station and fill up. See how much fuel you used.
Run the tank down to "nothing." and fill up w/V-power. Drive your circuit again, then head back to the Shell to fill up.
Here's what you'll find: You'll use 16.99% less gasoline on the Shell trip. Go ahead, ask me how I know...
Now, to run the numbers:
Let's say the price for the Shell fuel is $4.20.
Let's say you get 16.99% better fuel mileage. (That's worth $.71358)
$4.20
-.71358
$3.48642 energy equivalent to "BJ'S" gas. Are you paying $3.49 for BJ's gas? Your gettin' took, my friend...
