Check out the Top Tier Gas site. I had my Cadillac towed in and the dealership gave me a copy of their GM Advisory that they recommended Top Tier. I have not had a problem since in any of my GM products.

You will, as 100% gasoline has greater BTU then gasoline diluted with ethanol. And if the ethanol in the gasoline has absorbed any water(very likely) then it will have even less BTU. On the highway, I see about 1.5 MPG better gas mileage when I run 100% gasoline vs E10.

Enough about history. I use Hess premium in my Mercedes with no problems but I only use Shell premium in my vette.

Well I guess that you have never been to the Northeast. Leon Hess founded the company back in the 30's. At one point Hess owned the NY Jets football team. They are not a small company by any stretch.

Truth is, most gas is tranfered on the same pipeline to the region, but name brands put in their own additive packages, before delivery to the pumps. Name brands usually have better quality control and inspections for moisture content. If the owners manual says 91 or better octane, what you're wanting. While getting off topic, my sister was buying gas at the corner coffee stop, and not running good in the winter. Told her water, and buy gas elsewhere. She did, and all's well now.

I will only run Chevron 91 (CA has nothing higher) in my Z06 unless I can't find one then I'll use the 76 Gas Station. From my understanding the difference in gas is the additives of course, how "fresh" it is, and condition of the storage containers. I also won't use a pump that is all 3 grades in one, has to have a separate pump for each grade dont want ANY 87 getting in my car
91 octane

I only run top tier gasoline as GM recommends. The different oil companies use different additives, some being better then others, but all must meet the minimum Government standards. Top Tier additives is a cut above the minimum required. GM used to recommend not using any gas additives, just to use a top tier gas, but they have now changed that. Chevron Techron is recommended(repackaged under the GM label) since all the gas tank sensor problems they had with the C5's. Those of us with that had C5's know that using Techron worked.
In addition to running nothing but top tier gas in my Z06, I also run a 20oz bottle of Techron through the tank once a year(and also my supercharged Mercedes).
