What's the Difference Between Full Synthetic and Semi-Synthetic Oil?
1 Answers
Different base oils, applicable temperature ranges, additives used, replacement intervals, suitable vehicle conditions, and prices. Here are the details: Different base oils: Generally, the base oil of full synthetic oil is of a higher grade than that of semi-synthetic oil. Applicable temperature ranges: Full synthetic oil can be used in a wider temperature range. Under the same working conditions, semi-synthetic oil has higher usage requirements, while full synthetic oil can protect the engine with lower viscosity. Additives used: Semi-synthetic oil contains lower TBN (Total Base Number) additives, which shortens the oil maintenance cycle. Full synthetic oil contains higher TBN additives, which help extend engine life and provide some cleaning effects. Replacement intervals: Compared to semi-synthetic oil, full synthetic oil has a longer replacement interval, typically once a year or every 10,000 kilometers. Suitable vehicle conditions: Full synthetic oil can adapt to various harsh driving environments due to its excellent high and low-temperature resistance. Therefore, it is commonly used in vehicles with turbocharged engines or luxury models. Semi-synthetic oil is more suitable for economical models. Price differences: Full synthetic oil has higher production costs and is more expensive, while semi-synthetic oil offers better cost performance. Additional information: Synthetic oil: Engine oil manufactured using chemical synthesis methods. Depending on the intended use, the composition of synthetic oil can be adjusted. Engine oil: Also known as engine lubricant.
