The recommended oil for the Hyundai Genesis coupe 3.8 is 5w-30. It's crucial to use high-quality oil to keep the engine running smoothly. Over time, issues can arise with the oil, such as hearing knocking noises from the engine or experiencing a burning smell. Using poor-quality oil can even cause the engine to fail, potentially leading to a dangerous situation like a car explosion. Another consequence of bad oil is reduced gas mileage. It's important to get the oil checked regularly and replaced every 5,000 to 10,000 miles to prevent engine problems. Ignoring oil changes can result in serious engine issues.
