Brands of Gasoline = Actual Difference

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.
