What brand is the original Audi engine oil?
1 Answers
Audi's original factory-specific engine oil comes in two types: domestic and imported. The domestic engine oil is Audi's matching specialized oil, produced in Changchun City, Jilin Province, specifically designed for domestically produced vehicles. There is also a Castrol Edge Professional oil, primarily used for Audi imported vehicles. Below is relevant information about engine oil: 1. Mineral Oil: Mineral oil's base is derived from crude oil refining. After extracting gases, gasoline, diesel, kerosene, and heavy oil from crude oil, the mineral oil base is refined, leaving asphalt as the residue. The mineral oil base is transparent with a slight amber hue, similar to the color of salad oil. Typically, mineral oil is very low-cost, but because the mineral oil base oxidizes more easily, even though modern mineral oils contain various imported additives, their service life remains around six months. 2. Full Synthetic Oil: This oil contains only PAO or ester-based synthetic compounds, entirely manufactured chemically. Initially used in the aviation industry, it was later adopted in racing and is now widely used in passenger cars. The advantages of full synthetic oil include high cleanliness, excellent fluidity, superior cooling capability, and outstanding oxidation resistance. 3. Semi-Synthetic Oil: Semi-synthetic oil is a blend of synthetic oil and a portion of mineral oil, typically in a 4:6 ratio. It combines the benefits of full synthetic oil at a lower cost. While its performance is inferior to full synthetic oil, it is more affordable and has a slightly shorter replacement cycle compared to full synthetic oil.
