Is SAIC Volkswagen 0w20 engine oil fully synthetic or semi-synthetic?
1 Answers
It is fully synthetic engine oil. Below are the differences between fully synthetic and semi-synthetic engine oils: 1. Different quality: Fully synthetic oil is a high-grade oil product among engine oils, derived from ethylene and propylene dispersed from natural gas or gas in crude oil, which is then refined into lubricating fluid composed of large molecules through complex chemical reactions such as polymerization and catalysis; semi-synthetic engine oil contains a smaller percentage of high-performance fluids and includes conventional mineral oil, utilizing the poorer components of crude oil. 2. Characteristics: Fully synthetic engine oil has better high and low-temperature performance, a longer oil change interval, and is suitable for more severe vehicle conditions; semi-synthetic engine oil contains more mineral oil, has a higher pour point, and is more polluting to the environment.
