Is SAE 0W-20 Fully Synthetic Oil?
1 Answers
SAE 0W-20 grade is mostly fully synthetic engine oil, but this grade also includes semi-synthetic and mineral oils. Here are the specific introductions of engine oils: 1. Mineral oil: Refined from crude oil, usually with very low cost. However, as mineral oil oxidizes more easily, various imported additives are added. Its service life is about six months. 2. Semi-synthetic oil: Higher refining cost but with good oxidation resistance, making it a quite good long-lasting engine oil with a service life of about twelve months. Considering the balance between price and quality, semi-synthetic oil has the widest range of applications. 3. Fully synthetic oil: Chemically synthesized engine oil that can maintain lubrication even under conditions where the base oil fails.
