Answer
Hello and thanks for the question...I'll try to help.
Oil in your fuel system? Or oil clogging the PCV valve screen? Oil in your fuel won't cause a check engine light..........unless the mixture it about 1-2 gallons of oil to a tank of gas. As far as the screen goes...........it does get clogged. It is going to. That is where the oil is and it gets carboned up.
