The 2015 GMC Sierra requires 6 quarts of oil for optimal functioning. Using high-quality oil is crucial for engine performance. Over time, oil issues can arise, such as hearing a knocking noise from the engine or experiencing a burning smell. Poor quality oil can even cause the engine to fail. To prevent problems, it's important to regularly inspect and replace the oil every 5,000 to 10,000 miles. Neglecting oil changes can lead to engine problems or even a potential car explosion. Additionally, poor gas mileage may result from not maintaining proper oil levels.
