What is the difference between semi-synthetic oil and mineral oil?
2 Answers
The main differences between mineral oil and semi-synthetic oil are as follows: 1. Different components. Mineral oil: Mineral oil is based on mineral oil refined from petroleum, with additives added to it. It is relatively inexpensive but can only provide certain protection. Semi-synthetic oil: Synthetic oil is artificially synthesized, distinguishing it from mineral oil. It provides excellent lubrication for the engine, with outstanding performance in both high and low temperatures and high-speed lubrication. It is used in higher-end cars in the market. 2. Different effects. In terms of power, if the car travels a relatively long distance, mineral oil may lead to a feeling of insufficient power, while semi-synthetic oil still feels very powerful.
Mineral engine oil is a base oil directly refined from petroleum, which is more traditional and inexpensive, suitable for older vehicles or situations with limited budgets. However, its performance is average, with poor high-temperature protection and weak low-temperature fluidity, making it difficult to start in extremely cold weather. Semi-synthetic engine oil, on the other hand, blends mineral oil with synthetic components, providing better lubrication, cleaning, and high-temperature stability. It allows the engine to run more smoothly, with less noise, and extends the oil change interval. After switching to semi-synthetic oil, I noticed significantly less carbon buildup in the engine, and driving on highways feels more reassuring. Although the price is slightly higher, the longer maintenance intervals make it more cost-effective in the long run, making it a good choice for family cars.
