Should BYD Song Pro use 5W30 or 5W40?
2 Answers
BYD Song Pro uses 5W40 engine oil. Here are the relevant introductions: 1. Suitable range: This type of oil has a relatively high viscosity and is suitable for German or American cars. 2. Operation: New cars can use oil with relatively low viscosity, while older cars are better suited for oil with relatively high viscosity to ensure better engine performance. Below are the differences between 5W-40 and 10W-40 engine oils: 1. Grade: 5W-40 is synthetic oil and must be SN grade, which is the highest grade; 10W-40 is a four-grade oil, with a grade lower than SN and not reaching SN level. 2. Application temperature: The minimum application temperature of 5W-40 oil can reach minus 25 degrees Celsius; the minimum application temperature of 10W-40 oil can only reach minus 15 degrees Celsius. 3. Technology: 5W-40 adopts synthetic technology, producing oil through chemical synthesis. Depending on different application purposes, synthetic oil can adjust various components; 10W-40 is ordinary lubricating oil, composed of base oil and additives.
As a seasoned driver with years of experience in various car models, I'm often asked by friends about the best engine oil choice for the BYD Song Pro—whether to use 5W30 or 5W40. From my experience, it really depends on the specific driving conditions. The Song Pro's engine is designed for fuel efficiency, and most manuals recommend 5W30 due to its excellent low-temperature fluidity, smooth cold starts (especially suitable for northern regions or winter driving), and its ability to reduce fuel consumption by about 5%. However, if you frequently drive long distances in high-temperature southern areas or often push the engine at high speeds, 5W40's higher viscosity provides better high-temperature protection, preventing premature engine wear. Don’t overlook driving habits—if you drive smoothly, stick with 5W30; if you’re more aggressive, 5W40 might be the better choice. I recommend checking the oil level every 7,500 km and changing it promptly—don’t skimp on small expenses that could lead to major damage. This practice can extend your car's lifespan by tens of thousands of kilometers. In short, always refer to the owner’s manual for the most reliable advice—don’t just guess!
