The 2014 Jeep Grand Cherokee requires 5.9 quarts of oil for optimal performance. It is important to change the oil regularly, ideally every 5,000 to 10,000 miles. Neglecting oil changes can lead to engine issues, so using high-quality oil is crucial for smooth engine operation. Be mindful of potential signs of oil problems like a strong burning smell, as this could indicate a serious issue that needs immediate attention to prevent any accidents. Using old or low-quality oil can result in engine failure, characterized by knocking noises and reduced gas mileage.
In the USA, Jeep suggests using 87 octane fuel for the 3.6L engine and 89 octane fuel for the 2014 5.7L Cherokee engine. Even though the 5.7L engine can work with 87 octane gas, Jeep advises using 89 octane for the best engine performance.
