I ran my first couple of bottles of Redline DFC through the 300D and four of my injectors have started leaking. The one that is not leaking was replaced right after I purchased the car because it was already leaking. The milage on the first full tank was down to 20 mpg - city/hwy combined. I will be replacing leaking injectors this week. I guess that stuff really does clean that baby out. Otherwise the car ran great.
