i will have to dispute that. The manual and Dodge itself, along with SEVERAL auto publications say, wait for the computer to tell you. Mine has not, now not saying there isn't something wrong with mine but don't discredit the suggested oil changing patterns. Specifically you are not to change the Journey until 6k miles. Just bc in your 1979 Dodge Truck you change it every 2k, doesn't mean times have not changed. Oil break downs have been highly refined over the years.
