So my 2018 Taurus 3.5L duratec made a funny screeching/tapping noise this mourning at startup. Never done that before. Car only has 18967.7 miles. Oil has always been synthetic RGT 0W20 OR 5W20. Oil has 5773.6 on it. The only thing I can think the noise was either the cam phaser or maybe the starter got hung in the flywheel? Should I change my oil early or see if it does it again? Call Ford?
