What is the Difference Between Full Synthetic and Semi-Synthetic Engine Oil?
1 Answers
Full synthetic oil and semi-synthetic oil differ in the following aspects: 1. Full synthetic oil has a wider operating temperature range and longer service life; in terms of oil film requirements, synthetic oil can achieve the same effect as semi-synthetic oil with higher viscosity but at a lower viscosity. 2. Semi-synthetic oil is inferior to full synthetic oil in terms of high-temperature fluidity and viscosity. However, semi-synthetic oil performs slightly better in terms of cleaning properties. Therefore, it is not recommended for performance cars or turbocharged vehicles to use semi-synthetic oil. 3. Using semi-synthetic oil may result in insufficient engine cooling, accelerated component wear, and rapid carbon deposit formation.
