What type of engine oil is suitable for BYD Surui?
2 Answers
BYD Surui uses 5W30 engine oil, and it is recommended to use SN-grade full synthetic oil, as this type of oil has a high grade and excellent lubrication performance. Functions of engine oil: The main functions of engine oil are lubrication, cleaning, and heat dissipation. In terms of types, engine oil can be roughly divided into three categories: conventional, semi-synthetic, and full synthetic. When changing oil, any oil without the word "synthetic" is considered "conventional". Engine oil degradation period: Engine oil degrades over time. "Conventional" oil typically begins to oxidize and lose its effectiveness after about 3 months of exposure to air. This means that if you change the oil and don't drive for 3 months, you should still change the oil again. Synthetic oil lasts about 6 to 9 months. If you drive regularly, engine oil in China generally starts to degrade after 5000 kilometers.
Our family has been driving a BYD Surui for several years, and changing the engine oil has always been a priority. The most suitable oil for the car is 5W-30 synthetic oil, as recommended in the owner's manual. The specific model depends on the year, for example, models after 2015 often use this type. Synthetic oil is better than mineral oil, providing faster cold starts and not thickening in summer, protecting the engine and reducing friction losses. When choosing a brand, Castrol or Shell are good options—don't be tempted to buy cheap, off-brand oil, as it may cause sluggish acceleration or higher fuel consumption. It's recommended to change the oil every six months or 5,000 kilometers. Doing it yourself is quite simple—just prepare a funnel and container, and take safety measures to prevent oil spills and environmental pollution. Regular maintenance can extend the car's lifespan by ten years without issues, saving both hassle and repair costs.
