There are a few facts about gasoline that make whether you buy it at a name brand station or not almost irrelevant.

First, all gas is generic as it leaves the refinery. There may be differences due to local requirements due to season and pollution control requirements, but all of the refineries are dumping their output into the same pipeline distribution system. The output of a Mobil refinery gets mixed with the output of a Citgo refinery and etc. Here in the Chicago area we have 3 refineries that make the blend required for the local pollution control rules. A Citgo in Lockport, IL, BP in NW Indiana, and Exxon/Mobil in Joliet, IL. All three get the bilk of their crude in via pipelines primarily out of Canada. All three ship their output in the same pipeline distribution system. So up to the point where the big tanker truck picks up their load to deliver to your local fueling station, all gas is exactly the same.

Next, at the point where that tanker trailer is making its pickup, here is where the difference comes in. They put in the proprietary additives unique to each brand. The difference could be as little as a quart of additive in a 10,000 gallon tanker. So that tanker picking up a load for a Mobil station is likely carrying fuel that was refined at a combination of different companies, just that it contains the additives that are specific to Mobil. This is also the point where the ethanol is blended in. Ethanol cannot be transported via pipelines due to its propensity to pick up water. It is usually shipped by rail.

So the next time you think that one brand of fuel is better, just remember it is only the additives poured into that 10,000 gallon tanker that are different between brands. For me, if the Shell is 5 cents more than the Speedway or Sams Club, I'm buying the Speedway or Sams club and won't give it a second thought.

Damn, I've been using basic 87 octane. I had no idea that it recommended 89 octane! And 390HP? Damn, I wish I had 390HP out of my Hemi. I only have a bone stock 345HP. Oh well, at least it's a Hemi and not a Triton.

That sounds pretty harsh, it's an honest question and some people just don't know.

As far as the premium vs regular debate goes, all I can go on is on page 373 of the owners manual, "The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines."

That's enough to settle it for me in my unmodified truck. I have bought some 89, but could tell no difference, so I'll stick with whatever 87 that I find cheap that day.

And remember, that octane is a rating of a fuels resistance to preignition. The higher the number, the less likely it is to ignite before you want it to. It has nothing to do with how much power you get out of your engine.

Learn something new everyday....

But either way, I use the factory recommended 89. That's all I've ever put in it.

Its been stated many times throughout this thread, that if you have modifications such as a tuner, SC, or turbo, the use of premium would be sufficient...I you have a CAI, and exhaust, the manual calls for 87-89(as i put on the first page of this thread), 91+ will give you no advantage what so ever in mpg or hp on a stock low compression engine, thats just not how it works...If anything your making the engine run like garbage, and possibly causing abnormal or uncontrolled combustion inside the cylinders because of the higher octane rating...
