The only way I found to cure my stiction issues was to replace all the injectors with Ford remans and I tried all the additives. Night and day difference in running quality along with about 1 mpg improvement. I will run Motorcraft PM-22 in fuel when I am traveling just because I don't know the fuel I am buying.
