Well I have searched all over the forums and it seems people say 5-6 quarts depending on the year model..I have5 quarts now of mobil one and a motocraft filter and am going to change the oil today..I saw hayens reccomends 5 quarts..yet I heard there was a TSB changing the reccomended oil capacity for the older 4.6's ...can someone clear this up so I dont overfil or underfil? Thanks guys..
