Why does the new Mondeo use 5W20 engine oil?
1 Answers
The reason the new Mondeo uses 5W20 engine oil is that W20 oil has a relatively low viscosity grade, which is more suitable for some small-displacement naturally aspirated engines with lower maximum RPM requirements. Below is relevant information about engine oil: 1. Viscosity value: The number after W represents the viscosity value at 100°C. The larger the number, the higher the viscosity of the oil, and the better it protects the engine. For 5W20 oil, the number after W is 20, indicating a viscosity grade that is not particularly high. 2. Oil composition: Engine oil mainly consists of base oil and additives, with various types of additives such as dispersants, detergents, oiliness agents, rust inhibitors, pour point depressants, emulsifiers, and anti-oxidation and anti-corrosion agents.
