Is Fully Synthetic or Semi-Synthetic Motor Oil Better for Cars?
1 Answers
Fully synthetic motor oil is better for car maintenance. Fully synthetic motor oil has the following advantages over semi-synthetic motor oil: 1. Fully synthetic oil has better high and low-temperature performance: Fully synthetic oil can be used over a wider temperature range and has a longer service life. It can achieve the required performance with lower viscosity, whereas semi-synthetic oil requires a relatively higher viscosity to meet the same requirements. 2. Longer oil change intervals: Motor oil blended with synthetic oil has stronger oxidation resistance, significantly extending the oil change interval. Although the initial cost of the oil may be higher, it reduces the frequency of oil and filter changes. 3. Suitable for harsher driving conditions: Synthetic oil is better suited for higher-load engines, offering superior resistance to high temperatures and shear forces. Even at high engine speeds, the oil maintains its viscosity, providing more comprehensive engine protection. Additionally, synthetic oil is of higher quality and can improve fuel efficiency.
