Brands of Gasoline = Actual Difference

As far as I can tell, there's little difference between brands of gas. The condition of the tanks at the station can make a big difference. YMMV

Length of gas stagnation/quality of tanks simply never even crossed my mind...before my 370 I was a devoted Jeep guy and the last worry on my mind was quality of fuel in the engine given that I Seafoam and change the synth ever 3,000 miles (just how I do, don't care about cost issues and the 3,000 mile myth.) I was simply astounded by my Z's engine acting as though it had caught the schoolyard sickness after one sip of the Kroger fuel...I'm definitely grateful to everyone's comments regarding fuel and I think that in a seeming land of zero consensus there is one grand consensus: we'll all stick with what works for us - for me, that's Shell V-Power and will be until my car itself tells me otherwise.

I worked at a BP in college and before (6 years) and know that we were getting the same gas delivery as the stations around us, including an off brand gas station down the road. Also, the gas station having a newer underground tank is huge. Gas stations are allowed to have a certain amount of water in there tanks (it happens) and the older the tank, more water. The owner is supposed to clean the tanks often but that is expensive and I know some owners will not. How full the actual underground tank is with gasoline is a big thing as well. If you are the unlucky person who gets the gas when the gas stations tank is low and needs to be filled, you may get some water as well. There are too many factors. Each pump also has a fuel filter that needs to be changed often and can damage cars if they are not changed. You can tell the fuel filter is old in the pump if that pump is going very slow. If all of the pumps are pumping slow then the station is low on gas. I would suggest looking at stations that are just well kept.
