Jeep recommends having your 1990 Jeep Grand Wagoneer’s motor oil changed at regular intervals. Check out mileage and month info for your Grand Wagoneer in the above table. Outside of Jeep-recommended oil change intervals, your Grand Wagoneer may need an oil change if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by Jeep if you regularly haul heavy loads, drive in dusty terrain, adventure off-road, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your Jeep Grand Wagoneer. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
