The Difference Between Full Synthetic and Synthetic Engine Oil
1 Answers
Synthetic engine oil and full synthetic engine oil differ in the following aspects: 1. Different base oils: Semi-synthetic oil uses Group III base oil; full synthetic oil is a blend of Group III, IV, and V base oils. 2. Different replacement cycles: Semi-synthetic oil should be replaced every six months or 7,500 kilometers during use; full synthetic oil should be replaced every year or 10,000 kilometers during use. 3. Different operating temperatures: Full synthetic oil has a wider operating temperature range. Under the same working conditions, full synthetic oil can protect the engine with lower viscosity, while semi-synthetic oil has relatively higher requirements. 4. Different vehicle suitability: Semi-synthetic oil is more suitable for economical small-displacement vehicles with smooth driving; full synthetic oil can be used under various harsh conditions or for those seeking optimal engine maintenance. Additional information: Synthetic oil is a man-made lubricant. During production, various natural substances are chemically decomposed and synthesized with other materials to ultimately produce synthetic oil.
