I have a 2003 2.5 z4 with 70k. I was running low on fuel the other night so stopped and got some. It was running fine for a like 2 days then started to misfire but clear up and come back now it does it regularly. I bought the fuel system cleaner but was wondering how much I should put in there I have read the directions but also read about people using more than prescribed.
