There is so many negative articles about the Dodge 2.7 V6. From timing chain to bad bearings to sludge build up. I have changed my oil every 3000 miles but am switching to Mobil 1 to try to avoid any of the above problems. Hope to go 8 - 10 thousand between changes. Reasonable or not? Have a 2000 Intrepid with 70,000 on it now and would like to get many more. Thanks for your time and comments.
