What type of engine oil is suitable for the Volkswagen New Jetta?
1 Answers
It is recommended to use fully synthetic engine oil. Detailed information is as follows: 1. Fully synthetic engine oil is recommended due to its superior lubrication performance, which can extend the engine's service life. 2. Fully synthetic engine oil is a high-grade product in the engine oil category. It is derived from ethylene and propylene dispersed from natural gas or crude oil's associated gas, which then undergoes polymerization, catalysis, and other complex chemical reactions to form a lubricating fluid composed of large molecules. 3. Essentially, it utilizes the better components of crude oil, undergoes chemical reactions, and is artificially controlled to achieve the desired molecular structure. The molecules in fully synthetic oil are neatly arranged, naturally providing strong resistance to external variables. Therefore, it has superior qualities, such as excellent thermal stability, oxidation resistance, and viscosity change resistance, far surpassing those of mineral oil and semi-synthetic oil. Consequently, it is also the most expensive option.
