Can turbocharged cars use semi-synthetic oil?
1 Answers
Turbocharged cars can use semi-synthetic oil, but its service life, lubrication and cleaning effects, as well as its ability to resist high-temperature oxidation, are not as good as those of fully synthetic oil. Replacement cycle of semi-synthetic oil: In most Chinese cities, semi-synthetic oil can be replaced every 7,500 kilometers or 9 months. If there is too much dust in the air, the temperature is very low (-20 degrees Celsius), or the car is driven for short distances for a long time (each trip is less than 8 kilometers), it is recommended to increase the oil change frequency to 5,000 kilometers or half a year. Shelf life of semi-synthetic oil: The state clearly stipulates that the shelf life of sealed oil is basically within 5 years, and the shelf life of semi-synthetic oil is also within this range. However, semi-synthetic oil that has been opened will deteriorate faster, so it is best to use it within half a year. Of course, how long semi-synthetic oil takes to deteriorate also depends on the storage environment. The greater the temperature difference and humidity, the faster the oil deteriorates.
