Below are the benefits of full synthetic engine oil: 1. Low evaporation loss: Synthetic oil is generally a pure compound with a narrow boiling point range, resulting in significantly lower evaporation loss compared to mineral oil. This helps reduce fuel consumption, decrease exhaust emissions, and extend the lifespan of catalytic converters. Additionally, synthetic oil offers superior chemical stability, excellent radiation resistance, high oil film strength, and minimal foaming compared to traditional mineral-based oils. As a result, high-end vehicles typically opt for synthetic oil. 2. Strong high-temperature oxidation resistance: Synthetic oil exhibits far better thermal oxidation stability than mineral-based oils, meaning it is less prone to forming acidic substances and sludge due to oxidation. It provides adequate lubrication and effective protection for the engine under various harsh operating conditions, ensuring prolonged service life and stable performance over extended periods. In the same working environment, synthetic oil lasts much longer than mineral oil, so despite its higher initial cost, the overall expense is not significantly higher when considering fewer oil changes. 3. Excellent viscosity-temperature characteristics and low-temperature fluidity: Synthetic oil has a higher viscosity index than mineral oil, with less viscosity variation across temperatures. At the same high-temperature viscosity, most synthetic oils have lower pour points (or freezing points) and lower low-temperature viscosity compared to mineral oils. For the same oil film requirements, synthetic oil can achieve engine protection with lower viscosity.
