Im changing oil on my 2013 Durango R/T. All resources say filter should be Fram XG2 which i happen to have. Suprisingly this doesnt match what was put on my car by dealer. It has a longer filter only 3 inches in diameter versus the xg2 which is 3 5/8. Can anyone tell me why this is incorrect, other than welcome to Dodge? Also lower radiator hose hits the xg2 but main problem is threads are a different size and will NOT thread on. Please let me know what you are using specifically if you have the 2013 R/T ???
