What kind of oil filter are running? You should be using motorcraft they have a thread end bypass which Ford recommends. Using a universal oil filter will result in cold start noises which means premature engine wear. You don't have to use mobil 1 its not any better then any other synthetic oil. It just has good advertising. Id choose castrol edge over mobil 1 anyday. I run GTX 5w30 in the 04 gt with 3k changes. I have no noises
