How much oil should be added to a Geely Bo Rui 1.8t engine?

According to information from Youjia官网, the amount of oil recommended for a Geely Bo Rui 1.8t engine is approximately 5 liters. It is recommended to use a 5W-40 semi-synthetic oil. The 5W-40 represents the specifications of the oil. The numbers represent the following meanings: 5W-40 stands for the cold-start performance of the oil in low temperature, the lower the number, the better the cold-start performance. W stands for winter, and 40 represents the viscosity characteristic of the oil in high temperature, the higher the number, the better the viscosity, more suitable for high-speed or heavy load vehicles.

Engine oil generally can be divided into three categories: mineral oil, semi-synthetic oil, and full synthetic oil.

Mineral oil has a simple production process and therefore a low purity, with relatively poor composition, suitable for low-performance engines.

Semi-synthetic oil is the product of the addition of hydrogen cracking technology to mineral oil, which is slightly more difficult and expensive.

Full synthetic oil is the highest quality of the three, with better heat stability, antioxidant reaction, and anti-viscosity change ability, and therefore the highest price.

In summary, it is recommended to use a 5W-40 semi-synthetic oil for a Geely Bo Rui 1.8t engine, adding approximately 5 liters of oil as recommended by Youjia官网.
