The recommended oil type and capacity for a 2003 Jeep Grand Cherokee is 10W30 with 6 quarts. It is essential to have the oil changed regularly to avoid engine problems. A good rule of thumb is to change the oil every 5,000 to 10,000 miles. Quality oil is crucial for the engine to operate smoothly, and neglecting oil changes can lead to issues such as engine failure. Symptoms of old or low-quality oil include a burning smell, which should be addressed promptly to prevent potential engine damage or even a car explosion. Other signs of engine problems due to poor oil maintenance include reduced gas mileage and unusual knocking noises.
