Hello again I'm checking to see if anyone else has this problem. I have a 07 Jeep JK Unlimited 4X4 48,000 miles stock motor 4 inch lift running 35's. Then last 6,000 miles I've noticed that I've been using a quart every 1,000 miles. No leaks and not smoking nothing in the radiator. When I checked with the dealer they told me that was about right for it. Please Help?
