I have an 07 Taurus (Vulcan engine) I have been using the Motorcraft, FL-400s or whatever it is. I have seen people say the design helps the start up noise, etc. because the way FORD recommends the set up(something with the bypass, in the front?) Question is, I can get the Napa Gold for the price, what would you all recommend? Should I stay with the Motorcraft or does the Napa GOld have the same up front design ( or wix ) etc? Oil is Motorcraft Syn Blend or Mobil1 (5w20) and will be anywhere from 4-5k for miles.
