Bought a FiST a few days ago. Got about 300 miles on it now and noticed today a slight knocking sound after parking in the garage. Sounds similar to a sticking or not completely pumped up hydraulic lifter. Definitley not the injector tapping sound.
Other than that the car runs great. Was a hot 90F day and the 5W20 factory fill was probably like water
. I'll change the oil after a few more break in miles on her and see what happens.
