Is Audi Genuine Engine Oil Semi-Synthetic?
1 Answers
Audi genuine engine oil comes in two types: synthetic and semi-synthetic. Below are the differences between full synthetic and semi-synthetic engine oils: Different base oils: Semi-synthetic oil uses Group III base oils, while full synthetic oil is a blend of Group III, IV, and V base oils. Full synthetic oil uses higher-grade base oils compared to semi-synthetic oil. Full synthetic oil provides the best cooling capability and fluidity for engines. Turbocharged engines with more complex structures require higher-quality oil for maintenance. Different replacement intervals: Semi-synthetic oil should be replaced every six months or 7,500 kilometers, while full synthetic oil should be replaced annually or every 10,000 kilometers. Of course, the specific replacement interval may vary depending on the actual condition. Additionally, full synthetic oil has better cleaning performance and oxidation resistance than semi-synthetic oil, so its replacement interval is longer—typically once a year or around 10,000 kilometers.
