my sis in law has a 01 dakota with a 4.7 she bought new,changed oil on time every time,its now somewhere north of 200000 without a problem,she drove it back and forth to work about 50 miles one way 5 days a week
i changed out one in a durango and wasnt to impressed with all the plumbing ,chains,etc,and it was kinda a dog in the durango,and piggy on fuel
