The OP asked for Brand. Octane varies from area to area. For example 94 octane is not available at 10,000 feet in Colorado. Highest octane is a given.

Higher Octane in Cal
Hi Larry,
Google race gas or non ethanol and you may find a dealer near you. If you mix race gas you can dial it in to hit around 93/94 octane for those rally drives. Expensive, but worth it. Or, buy some Amsoil octane boost. Will raise you 2 to 2.5 octane points...so 93.5.

But and this is where some stations try to earn your business - is in their additives they put in their allotment - whatever part per billion of what the heck ever "drive your engine clean" *stuff* that they consider proprietary that may be. And no, you don't have a right to know what that is is - bc you Porsche is eating it - not you.
I buy the highest octane whenever is the cheapest - in my case Sam's.
If you want to add *Twinkies* in the form of octane booster or line cleaner I'd say get that at the WalMart or the parts store that has to tell you whats in the bottle.

Well keep in mind that that the *only* difference in your gas is the additives. My inlaws owned several gas/diesel stations here in the midwest. The Sam's pumper is getting the very same gas as that BP pumper. It goes on the basis of what you "put in" in theory - so Conoco puts in 4 million barrels at the Terminal in in gulf - they are allotted or granted those 4 million barrels wherever terminal they take out - from Maine to Calif.

There are allowable differences in the content of gasoline, differences in the make up of gasoline (there are limits/tolerances of what gasoline can contain prior to any additives being added, what gas can weight, its BTU content, and so on) that there can be noticeable differences between the gasoline produced by different refineries.
A few years back, a gasoline test done by Evo magazine -- a UK car mag -- found that supermarket gasoline while it could be very good, as good as name brand gasolines, varied too much and this was due to the mix of refineries/supplies the supermarket gasoline purchasers used.
OTOH, the name brand gasoline outlets used fewer refineries and the same one or ones, and as a result their product was more consistent.
The recommendation was to buy from a name brand station to get consistently the best gasoline and to buy from a busy station to get the freshest gasoline.
Generally a busy station offers the lowest or low prices so one gets a good quality, a consistently good quality of gasoline, fresh and at a good price.
As for additives in gasoline, my belief is if one is buying a gasoline that he feels he needs to improve with additives he's buying the wrong gasoline.
Sincerely,
Macster.

Sorry, that's not true.

Ok, let's slow down
The intent of my post/question was mearly to see what "brands" people were using. I'm personally torn between Shell (which I've used for years,) Mobil or Chevron. Here's why; I read an article about detergent gas and it concluded that for regular 87 octane Mobil had the most detergent and for super 93 octane Shell had the most, they concluded that the high detergent would keep the engine cleaner therefore better for the car.
Note: I have no experience in this area and these were not my conclusions.

. Totally agree on Shell's additives. I used to like Amaco's better - but that's when I had a Big Block that was over cammed and it wouldn't run very well w/o high octane gas in replacement of the Ethyl
