Neglecting the oil can lead to various issues, such as engine failure and a strong burning odor. It is important to address these problems promptly to prevent a potential explosion. Additionally, you may notice a knocking noise coming from the engine and experience reduced gas mileage. Regular oil changes are necessary, typically recommended every 5,000 to 10,000 miles. Failing to change the oil can result in serious engine problems.
