Re: Grand cherokee
Both are sensitive to regular maintenance. One issue particularly on the 4.7 is that they are put together with tight clearance. When they wear from high milage you need to up the viscosity on the oil or they will fail. That thin oil is fine when new and gives a little better milage but is inadequate later
