19.3 seems about the best I can get, even after traveling down 75 miles of interstate.
Will Seafoam, Marvel Mystery Oil, or Lucas added to gas help? What the best/safest to use, and can it be used often?
I suspect the oil was not changed as often as I would do it, as it was a Hertz vehicle.
Already did the fuel system treatment at a Ford dealer but that did nothing to help.
