What type of Fuel does a 2007 f150 v6 4.2L take? Vehicle did not come with a manual. Need to refuel. You can down vote my question. I just need information. I contacted ford dealership they say they will get back to me. They have not yet. Contacted Ford company via Facebook and sent me to a generic place with generic information about f150s for the year of 2007. However Who know if it is for v6 4.2L engines. I'm afraid to put the wrong fuel in my vehicle which might destroy my engine. Any advice would be nice. Thank You.
