Should the New Santana use 5w30 or 5w40?
2 Answers
The New Santana uses 5w40 engine oil. Introduction: Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil. Composition: It mainly contains anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines. Functions: The primary functions of engine oil are to reduce friction and wear on moving parts, and to remove sludge (one of the functions of dispersants) and varnish (detergents) from the engine. It also neutralizes acids produced from fuel and lubricant oxidation (detergents), improves piston ring sealing, and cools the engine by carrying away heat from moving parts.
When choosing engine oil for the new Santana, should I go with 5w30 or 5w40? Having driven Volkswagen cars for many years, based on experience, 5w40 is generally recommended. Volkswagen engines are designed with a focus on high-temperature performance, and 5w40 offers better protection in summer, reducing engine wear. While 5w30 has better low-temperature fluidity and is suitable for northern regions, it may not be as stable. Check the manual to confirm VW standards such as 502 00, which typically specify 5w40. Choosing the wrong oil can lead to slightly increased fuel consumption or louder engine noise. For regular maintenance, use fully synthetic oil and change it every 7,500 kilometers to extend engine life. Remember to adjust slightly based on climate—using 40 year-round in the south is more convenient.
