Own 2 Jeep Compass no problem with oil. I keep checking to see if there is a problem. My wife goes to dealer for oil change and they use penzoil no problems. I use Valvoline 0-20 full syn that meets specs and it seems I have to add a little bit between oil changes. I went 10,000 between oil change because the oil was still clean. I use mopar filter from Walmart. So far we love our compass. Great ride, accelerates nice. We have the Asian 6 speed tranny. Wife has 2300 miles since dealer changed oil and still at full line. My opinion, some people exaggerate and I am sure there is a lemon or two that have a real case.
