Ok new the forum. Lots of info here i like and i hope you can help me. I have owned an 08 commander with 4.7 for the past 6 months with 26000 miles on it and love it. I have a problem with oil consumptiom. My oil light was comming on only after driving 2400 miles after an oil change. I was 4 quarts low. not good in my opinion. The dealer is telling me that it should use 1 quart per 1000 miles. still dosent add up why am i 4 quarts low. In the 6 months i have had it I have had the cat replaces EGR valve replaced radio/nav system flashed along with the trans flashed. good thing for warrenty. Its my first time owning a jeep and have not been happy. does anybody else have this problem. Do I have to start driving around with a couple qts extra oil around on a fairly new truck or what.
