I have been online all night and I am really starting to freak out about what I did. My engine light came on. I was over due for my oil change by a month and the last time the guy said my oil was a quart low. I checked the oil stick and it really looked like it was WAY low. So I went to the store (I borrowed a friends car) and bought the 5 quart bottle of the appropriate oil and put it in...very slowly so I would not over fill it. Well, it took the whole 5 quarts! Thank goodness I did not drive the car. I thought I should let the engine 'absorb' all that oil. Well, I couldn't sleep because I was nervous about what I did, and here I am. I have read about different reasons the engine light came on. I also read that too much oil is bad and how could I have gotten that much oil in the car! Yes, I am blonde, but I think this is one of the dumbest things I have ever done. Can I undo this in some way? Thank you for any help.
