What are the benefits of fully synthetic engine oil for cars?
1 Answers
Fully synthetic engine oil offers benefits such as low evaporation loss and strong high-temperature oxidation resistance. Below are detailed explanations of the advantages of using fully synthetic engine oil: Low evaporation loss: Synthetic oil is typically 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 engine oil exhibits superior chemical stability, excellent radiation resistance, high oil film strength, and minimal foaming compared to traditional mineral-based engine oils. As a result, high-end vehicles generally opt for synthetic oil. Strong high-temperature oxidation resistance: Synthetic oil demonstrates far better thermal-oxidative stability than mineral-based engine oils, meaning it produces less acid and sludge due to oxidation. Under various harsh operating conditions, it provides adequate lubrication and effective protection for the engine, thereby offering a longer service life and ensuring 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 factoring in fewer oil change requirements.
