What is the best engine oil for Volkswagen Santana?
1 Answers
Volkswagen Santana uses 5W40 engine oil. Below is an introduction about engine oil:1. Concept: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks in the engine. It is often referred to as the 'blood' of a car. Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics. These additives are an essential part of the lubricant.2. Performance: Lubricity: The ability of engine oil to reduce friction, minimize wear, and prevent metal sintering under various conditions is known as its lubricity. The viscosity of engine oil is a key indicator of its lubricity. Low-temperature operability: The performance of engine oil that ensures easy starting and reliable oil supply in low-temperature conditions is referred to as its low-temperature operability. Viscosity-temperature characteristics: The property of lubricating oil to change viscosity with temperature fluctuations is called viscosity-temperature characteristics. Good viscosity-temperature characteristics mean that the oil's viscosity changes minimally with temperature.
