I have a FoST with the 2.0L turbo and I have none of these problems. And I drive it like it's stolen. I do 5k OCIs with whatever is on sale: M1 EP 5w-30, M1 0w-40, PUP 5w-30, Castrol Edge 5w-30 LL, whatever is cheaper at the given moment. The only complaint I have is with the direct injectors diesel-like sound.My Ford 2.0L non turbo D.I. is doing this too. fuel mileage is down to 21mpg ave.
Engine sounds like it is going to throw a rod, and has constant TC "grinding" noise. I was going to change the oil yet again pull a sample and run a UOA. I don't know if I should go to the dealer first as last time I was there fo a safety and emissions inspection they blew me off. I have had to change the oil at 2k miles twice in the past year. First was Valvoline Advanced 5W20 now it has Edge 5W20.
I don't know why I'm using syn. Might was well run a 10W30 QS.
Just decided I'll call the service manager and skip the usual waste of time with service writers. Now my CARFUTZ service history will get a red flag and I can't unload the junker if I get no satisfaction - that is my número uno concern
