Other fuels may contain additives which make your Ford™ engine seem imperfect. A few misguided people are tempted by the siren call of the independent fuel suppliers to use something other than the Ford™ fuel specially made for your needs. When things go wrong, they spread rumors that Ford™ vehicles suck, when it was simply their misguided fault.
And that's why, as the proud owner of a Ford™ vehicle, you must go to a Ford™ gasoline station to buy Ford™ fuel. That's Ford™ fuel, available from a Ford™ station somewhere in your state.
