In car maintenance, selecting the right oil is crucial to maintaining engine performance and extending vehicle life. For Ruiyi models, choosing the right oil type not only ensures the best operating condition of the engine, but also effectively reduces maintenance costs.

The type of oil recommended for use in Ruiyi models depends mainly on the design of the engine and the manufacturer's recommendations. In general, Ruiyi models are suitable for using SN grade or higher oils that meet API (American Petroleum Institute) standards. These oils usually have good cleaning properties, high temperature resistance and oxidation resistance, which can effectively protect the engine and reduce wear.

In addition, depending on the specific engine model and operating environment of Ruiyi, the viscosity grade of the oil may also need to be considered. For example, if the vehicle is mainly used in cold areas, it may be necessary to choose a low-viscosity oil, such as 0W-20 or 5W-30, to ensure that the engine can start quickly and reduce wear at low temperatures. In hot areas, higher viscosity oils such as 10W-40 or 15W-50 may be needed to provide better high temperature protection.

When selecting engine oil, the brand and quality of the engine oil should also be considered. Oil from well-known brands is generally more reliable because they undergo strict quality control and testing. At the same time, regular replacement of oil and oil filters is also a key step in maintaining engine health. It is recommended that maintenance be carried out at the vehicle manufacturer's recommended cycles to ensure optimal vehicle performance and extend engine life.

In short, selecting the right oil for Ruiyi requires comprehensive consideration of engine type, operating environment, viscosity requirements, as well as engine oil brand and quality. By correctly selecting and regularly changing oil, the engine can be effectively protected and the long-term stable operation of Ruiyi can be ensured.
