Changing oil regularly is essential for maintaining the health and performance of an engine, as it directly affects the lubrication and overall functioning of the vehicle. The recommendation to change the oil every 5,000 kilometers is a well-established guideline for many vehicles. This interval allows sufficient time for the oil to accumulate contaminants, including dirt, metal particles, and combustion byproducts, which can impede the engine's performance if not addressed.

Routine oil changes help to ensure that the oil retains its viscosity and protects engine components effectively. Over time, oil degrades and becomes less effective, which can lead to increased engine wear, overheating, and ultimately, more severe mechanical failures. By adhering to the 5,000-kilometer interval, you're supporting the long-term health of your vehicle’s engine and contributing to better fuel efficiency and lower emissions.

While some vehicles and modern synthetic oils may permit longer intervals, sticking to the 5,000-kilometer frequency is a conservative and effective approach, especially for novice drivers who may be less familiar with their vehicle’s specific oil requirements.
