What happens if you do not change the oil in your car?

If you do not change the oil in your car, the oil can become contaminated with dirt, debris, and metal particles, leading to reduced lubrication and increased friction. This can cause engine components to wear out more quickly and may result in overheating or serious damage. Over time, the oil can break down, losing its effectiveness, which could ultimately lead to engine failure and costly repairs. Regular oil changes are essential for maintaining engine health and longevity.
