I have found that you get the best mileage when you use the grade ( reg, mid, prem.) recommended by the mfg, and consistently buy your gas from the same station....

I work at a Fuel Wholesaler in Michigan. It really doesn't matter where you get your fuel from. I know that in the Michigan Detoit Metro area all of the gas at any gas station has 10% ethanol in it. This makes it cheaper for the consumer but it does cause the MPG to go down a little. However, you cannot get straight gas anymore, so I guess we just have to deal with it. Also if you get your gas from a Branded station like Shell or Marathon or Sunoco, etc., you will probably pay a little more. Any gas station that isn't a brand name can get the same fuel as the Sunoco's or Marathon's but it doesn't cost them as much since it isn't branded fuel. The only way to get straight gasoline anymore is from a supplier like my work that can deliver it to your home or business in small quantities like 150-4000 gallons.
Hope this helps!

IIRC, federal law mandates that all unleaded fuel have some amount of detergents and the like intended to keep the fuel system clean. That doesn't stop me from throwing a can of SeaFoam in every 5,000 - 10,000 miles just to be sure.
Suggest to run the octane that your car was intended to burn. For most, this is 87. Running a higher octane fuel can sometimes work against you, leading to unnecessary carbon buildups.
One good thing about the ethanol-blended fuels - shouldn't need to worry about fuel line icing
~ Even though it will decrease mileage by about 3% - ahh, the things we do for clean air.
IMO, the best thing you can do for mileage is to adjust your driving habits. Easy off the line, anticipate stops to minimize brake use, and keep your speeds within reason. A car in good tune also helps - chase after those 'check engine' light flags, do regular maintenance, etc.
