What Type of Engine Oil is Suitable for the Audi Q3?

[OAlaina]

Audi Q3 should use fully synthetic engine oil. Below is an introduction to fully synthetic engine oil: Introduction: To achieve better lubrication, humans have chemically synthesized various types of engine oil based on base oils, which is known as chemically synthesized engine oil. Synthetic engine oil manufacturers produce different types of engine oil according to user requirements, and the composition of synthetic engine oil can be adjusted based on its intended use. Definition: According to the official explanation, synthesis refers to the process of achieving the desired molecular form through chemical reactions under human control. The largest component of engine oil is the base oil, which can be classified into five categories based on specification grades. Among these five categories, base oils of categories I, II, and III are referred to as mineral oils, while only categories IV and V can be called synthetic oils. Among these, category V base oil is polyol ester (POE), and category IV base oil is polyalphaolefin (PAO). Therefore, the simplest understanding is that engine oils blended with category IV and V base oils without the addition of mineral oils can be referred to as fully synthetic engine oils.
