hi,new member here ,im going to bring up a topic im sure has been asked before...so i have a 14 gt w the track pack..same motor as a regular coyote,ford says to use full synthetic 5w50..not sure why but what i gather is that using 5w20..or 5w30 or 15w50 or 10 w30 will all work ,for different driving styles?...thanks for reading this..just bought it a few days ago black 5.0 6m w track pack got it with 3200 miles on it..traded my 08 black bullitt for it..already waiting on the ups guy..
