The recommended oil for the 2012 Mercedes GL450 is 5W-40. Using high-quality oil is crucial to ensure the engine operates smoothly, as using subpar oil can lead to engine failure. An indication of bad oil is a foul burning odor, which should be promptly investigated to avoid potential hazards like the engine catching fire. Additionally, unusual knocking sounds from the engine and decreased gas mileage may occur. It's important to change the oil every 5,000 to 10,000 miles to maintain optimal performance and prevent engine problems. Failure to do so can result in significant issues down the road.
