I am very frustrated so hopefully somebody knows the answer. I have a 2007 3500 duallie. . truck was serviced at 7800 miles by dealer. I bought the truck and changed the oil again at 9400 and again at 12,400. . I now have 14,300 and get a change oil on the over head. I never knew about resetting this since it has never come on. Reading my latest mag just received, it says not to ignore this warning as it is not based on mileage. I have a Jucie Edge and almost always drive through a Regen and use the truck mainly on the highway when I use it... any comments are most welcomed. . I have not had any codes or issues with the truck but don't want to have to change oil every few thousand miles... . thank you... . Steve
