Jeep recommends having your 1991 Jeep Grand Wagoneer’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Your Grand Wagoneer may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, smell oil inside the car, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Jeep if you regularly haul heavy loads, frequent dusty roads, adventure off-road, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your Jeep Grand Wagoneer. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
