How Many Kilometers to Change Synthetic Engine Oil?

[LeAdriel]

Full synthetic engine oil should be replaced every 12 months. Below is relevant information about full synthetic engine oil: 1. Introduction: (1) To achieve better lubrication effects, humans have chemically synthesized various engine oils based on base oils, which are known as chemically synthesized engine oils. (2) Synthetic engine oil manufacturers produce different types of engine oils according to user requirements, and the composition of synthetic engine oils can be adjusted based on their intended use. 2. Definition: The official explanation of synthesis is: achieving the desired molecular form through chemical reactions under controlled conditions, a process called synthesis. 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, Group I, II, and III base oils are referred to as mineral oils, while only Group IV and V base oils can be called synthetic oils. Group V base oils are polyol esters (POE), and Group IV base oils are polyalphaolefins (PAO). Therefore, the simplest understanding is that engine oils blended with Group IV and V base oils, along with mineral oils, can be referred to as full synthetic engine oils.
