How is the quality of 0km motor oil?
2 Answers
0km motor oil is a first-tier domestic brand with excellent oil quality. Below is relevant information about motor oil: Composition: Motor oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties, while additives are an important part of lubricating oil. Types of motor oil: SAE viscosity grades for winter oils are 0W, 5W, 10W, 15W, etc. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the low-temperature viscosity and the lower the applicable minimum temperature. SAE viscosity grades for summer oils are 20, 30, 40, 50, with higher numbers indicating higher viscosity and higher applicable maximum temperatures. SAE viscosity grades for all-season oils are 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, etc.
As an enthusiast who frequently studies automotive lubrication systems, zero-kilometer oil refers to the factory-fill oil that comes with a new car, and its quality is typically quite high. This oil is carefully selected by the automaker, specifically designed for the break-in period of a new engine. It uses synthetic or semi-synthetic formulations with viscosities such as 5W-30, effectively reducing friction and wear. When I bought my first new car, I noticed the engine ran smoothly with minimal noise after just 1,000 kilometers. This is because the factory-fill oil contains high levels of detergency and anti-oxidant additives, preventing the accumulation of metal particles. However, after the first service (usually around 5,000 kilometers), it must be replaced; otherwise, the oil will degrade, leading to increased fuel consumption or engine damage. A reminder to everyone: always check the manual for the correct oil specifications—don’t compromise quality to save money. The break-in period is critical for the engine, and using high-quality oil can extend its lifespan. Also, pay attention to seasonal changes; in cold regions, the oil needs good flow properties. During routine maintenance, regularly check the oil level and quality to avoid minor issues turning into major problems.
