Well, since 2005 Ford MotorCompany recomends BP fuel, and even install factory gas caps with the BP logo.

...Ford recommends BP fuel for all of its 2006 Ford-branded vehicles. BP is among the companies who routinely test their base gasoline, making sure that their gasoline has the same detergency performance as originally certified.
Since industry standards don't guarantee it, "Look for brands that promote good detergency," says Misangyi. "The ones who state it, are probably doing it right."
You probably don't need to be spending on any aftermarket cleaning products either. Ford's Owner Guide notes it should not be necessary to add any aftermarket cleaning products to your fuel tank as long as you continue to use the fuel and octane rating recommended by the manufacturer.
"If customers need an additive due to engine deposits, or bring the vehicle in for service due to a performance deficiency, they should probably switch the brand of gasoline they're using," says Misangyi. "A clean engine provides better fuel economy"...
