The frequency of engine oil changes depends on various factors, including the vehicle's make and model, the type of engine oil used, driving conditions, and the manufacturer's recommendations. In the past, the common practice was to change engine oil every 3,000 kilometers. However, modern vehicles and improved engine oil formulations have extended the recommended oil change intervals.

Most vehicles today, especially those using synthetic engine oils and adhering to API SP or API SN service categories, can go much longer between oil changes. Typical oil change intervals for modern vehicles range from 5,000 to 12,000 kilometers, or even longer, depending on the manufacturer's guidelines.

To determine the appropriate oil change interval for your specific vehicle, it's essential to consult your vehicle's owner's manual. The owner's manual provides the manufacturer's recommended maintenance schedule, including the ideal oil change interval based on the vehicle's design and engineering.

Some factors that can influence oil change frequency include:

Vehicle Age and Condition: Older vehicles or those with higher mileage may require more frequent oil changes to ensure optimal engine performance and protection.

Driving Conditions: Severe driving conditions, such as frequent stop-and-go traffic, towing, driving in extreme temperatures, or off-road driving, can place additional stress on the engine and warrant more frequent oil changes.

Synthetic vs. Mineral Oil: Synthetic oils generally have longer oil change intervals compared to mineral oils. If your vehicle uses synthetic oil, you may be able to go longer between oil changes.

Personal Driving Habits: Aggressive driving, short trips, and frequent engine start-stop cycles can impact oil life and may require more frequent oil changes.

Always follow the manufacturer's recommendations for oil change intervals to ensure the engine operates optimally and to maintain warranty compliance. Regularly changing the engine oil at the appropriate intervals is essential for engine health, longevity, and fuel efficiency.
