I just picked up a 2002 with the 2.0 ltr engine and can't find any info on how much oil it requires. I just changed it and put in 4 qts. The dipstick seems screwy :? like there is oil runing vertical instead of horizontal. I think it should take more but 4 qts looks about right. I don't have a manual so thats why the question. More than 4 qts? Bueller, Bueller???
