Let's compare the "quality" of diesel at four stations:

First, Top Tier diesel at a "mom and pop" station that's been in the tank since July (they don't sell much diesel)

Second, ULS diesel (not bio fuel) that's at the station across the street. It's been in the tank since September (they sell more than mom and pop, but not by a lot)

Third, Top Tier diesel at another station that does sell more diesel, but there's a diesel delivery truck filling the tank as you drive up. (adding fuel to the existing fuel stirs up the sediment in the station's storage tanks)

Fourth, 10% bio-diesel at a reputable truck stop that's been in the tank since 2 days ago, all the tank sediment has settled to the bottom of the tank, the fuel is fresh and there's no question of water content in their fuel.

Which would you choose? Why ??

The point I'm making is that there's no "constant" in where to select fuel and just because "labeling" is present, that doesn't mean fuel at that station is "better/best" of the available selections.... YMMV
