How often should semi-synthetic engine oil be changed in a car?

[NaomiDella]

Semi-synthetic engine oil should be changed every six months, with a replacement cycle of approximately 7,500 kilometers. Proper oil changes ensure that the car operates within normal parameters while providing better performance. Semi-synthetic oil is produced using semi-synthetic base oil, which is purified from mineral oil through hydrocracking technology. It is a mixture of mineral oil and fully synthetic oil in a 4:6 ratio, serving as an ideal transitional product from mineral oil to synthetic oil. The exact timing for an oil change may vary depending on the city, environment, and driving habits. If the city has high levels of airborne dust, extremely low temperatures (below -20°C), or if the car is primarily used for short trips (each drive under 8 kilometers), it is recommended to change the oil more frequently—every 5,000 kilometers or every nine months. Keep track of the intervals between oil changes and observe the driving experience after each change. If the car feels smoother and quieter after an oil change, it indicates that the previous interval was too long, and the next change should be scheduled sooner. After a few adjustments, you can determine the most suitable and accurate oil change interval for your vehicle.
