What type of engine oil is suitable for Volkswagen 1.4T?
1 Answers
Volkswagen 1.4T uses 0W40 engine oil. The 1.4T is a direct-injection turbocharged engine with a complex working environment inside the cylinders, requiring the oil to maintain good stability under high temperature and pressure. 0W40 oil exhibits strong fluidity under high temperatures and has high viscosity, allowing the oil film to effectively coat the cylinder surfaces for superior lubrication. Classification of engine oil: Automotive engine oils are divided into three types - mineral oil, semi-synthetic oil, and full synthetic oil. Mineral oil is only suitable for low-end vehicles or some new cars. Semi-synthetic oil is a blend of conventional oil and synthetic base oil, generally suitable for non-turbocharged mid-range models. Full synthetic oil has excellent high-temperature volatility resistance and deposition capability, making it suitable for high-temperature, high-speed, high-compression ratio engines like turbocharged engines. Functions of engine oil: Lubrication to reduce wear - There is rapid relative sliding between the engine's pistons and cylinders, as well as between the main shaft and bearing shells, which can easily cause wear. High-quality oil forms a sufficiently thick oil film between these sliding surfaces to separate them and reduce wear. Cooling - The oil carries heat back to the oil pan and dissipates it into the air, assisting the radiator in cooling the engine. Cleaning - Good engine oil can circulate carbon deposits, sludge, and worn metal particles from engine components back to the oil pan, flushing away contaminants generated on the parts' working surfaces through the flow of the lubricating oil.
