Should Volkswagen Bora Use Semi-Synthetic or Fully Synthetic Engine Oil?
1 Answers
Whether Volkswagen Bora should use semi-synthetic or fully synthetic engine oil depends on the oil change interval. Fully Synthetic Engine Oil: Fully synthetic engine oil is a high-grade lubricant. It utilizes superior components from crude oil, undergoes chemical reactions, and achieves the desired molecular structure under controlled conditions. The molecular arrangement of fully synthetic oil is orderly, giving it strong resistance to external changes. For driving in most cities across China, fully synthetic oil can be changed every 10,000-12,000 kilometers or approximately once a year. Semi-Synthetic Engine Oil: Semi-synthetic engine oil is formulated using semi-synthetic base oil, specifically Group III base oil internationally. It is a refined product derived from mineral oil through hydro-cracking technology, consisting of a 4:6 ratio of mineral oil to fully synthetic oil. The purity of semi-synthetic oil is very close to that of fully synthetic oil, but its cost is slightly higher than mineral oil. It serves as an ideal transitional product from mineral oil to synthetic oil. For driving in most cities across China, semi-synthetic oil can be changed every 5,000-8,000 kilometers or approximately every six months.
