I've got a 1997 Cherokee with the 4.0L and just reached 197,000 miles. This is my daily driver and I've taken great care of this vehicle over the years. I keep on top of fluids and filters and have signed my vehicle up online at MeMaintain.com > Home
to remind me about various maintenance items. I think this engine is good to at least 300K miles. Anyone else got some high miles on their original 4.0L?
