Where the $0.01 gap actually comes from
None of it is tax. This is the case people assume never happens: New York is dearer at the pump while taxing a gallon $0.10 less than Pennsylvania. The whole gap is the cost of the fuel itself — refinery proximity, pipeline access and state blend rules — and the tax difference is quietly shrinking it.
