I have a 1997 Chrysler Cirrus LXi and i have to refill the oil like every 2-4 weeks. BIG oil consumption… well.. a few days ago I filled it and I didn't notice how much. Well it looks like its a quart over. I'm going to drain it tomorrow and refill but.. have I caused any damage with it in these few days? The light only comes on when its idling in drive. In park when the RPMS go up.. it goes off… or when I drive in general. I also noticed one time white smoke out of the exhaust too… someone please help me? This is my first car and I may have ruined it totally.
