The Difference Between Mineral Oil and Semi-Synthetic Oil

[OHazel]

Mineral oil and semi-synthetic oil differ in the following aspects:1. Price difference: Mineral oil is based on petroleum-refined mineral oil with additives, making it relatively cheaper; synthetic oil is more expensive. 2. Performance difference: Mineral oil, being cheaper, provides basic protection and is the most fundamental type of oil; synthetic oil is entirely synthesized and differs from mineral oil, offering superior lubrication for the engine. Its high and low-temperature performance and high-speed lubrication are outstanding, typically used in high-end cars, racing cars, and vehicles in extreme climates. 3. Engine noise: In terms of engine noise, there isn't a significant decibel difference between using mineral oil and synthetic oil in the same car. The only difference lies in the sound quality—engines using full synthetic oil produce a more pleasant and powerful sound compared to those using mineral oil. 4. Power output: Initially, there isn't much difference between mineral oil and synthetic oil in terms of power output. However, over time, the power output with mineral oil tends to decrease linearly. After driving 3,000 kilometers, it becomes evident that synthetic oil maintains a much stronger power output.
