I do not find that true as my wifes Jeep Liberty has 140k grease miles of it 205k total miles and it runs great. Jeep CRD are not really that reliable either which makes it even more shocking.

Nobody here is going to buy my Mercedes, it runs funny now because I have been abusing it for so long. I did short flushes a lot and I let it run 10 hours a day and only go 150 miles. It spends a lot of time idling and under full throttle, But it is still a good car I am hoping that after I install the water injection system it will clean up the intake and run better. (But it turns out that is a pain to install, Maybe this weekend.)
