What type of engine oil is suitable for BYD Song?
2 Answers
BYD Song Max is equipped with a 1.5L turbocharged engine, which requires either 5W30 or 0W30 full synthetic engine oil. Additional information: 1. Function of engine oil: Engine oil is an essential component that every car owner interacts with daily. It plays a crucial role in the engine's operation, often referred to as the "blood" of the engine. Without oil, the engine cannot function properly. Beyond lubrication, engine oil performs multiple functions including cleaning, sealing, buffering, rust prevention, and heat dissipation. 2. Winter recommendation: During winter, 0W oil is recommended due to its superior low-temperature protection properties, which help reduce engine wear. The number following "W" indicates the oil's high-temperature viscosity - higher numbers represent greater viscosity. When selecting engine oil, it's important to consider both your vehicle's engine technical specifications and your driving habits. Most turbocharged engines can use either 30 or 40 viscosity oil. Horizontally opposed engines typically require 20 or 30 viscosity oil, while most naturally aspirated engines can use 20 viscosity oil. It's crucial to choose oil with appropriate viscosity - neither too high nor too low.
As a BYD Song owner with tens of thousands of kilometers of driving experience, I recommend using 5W-30 full synthetic engine oil as specified in the user manual. This viscosity grade performs well in all seasons - it won't boil in summer heat and ensures quick cold starts in winter to prevent engine freeze damage. I've had stable results using Castrol or Mobil brands, changing oil approximately every 10,000 km. Never compromise with conventional oil - synthetic provides better protection, reduces wear, and improves fuel efficiency. Checking oil level is simple: park on level ground, wait five minutes after turning off the engine, then check that the dipstick reading falls between the markers. Using incorrect viscosity like 10W-40 will cause engine noise and potentially accelerate wear. Always replace the oil filter during changes for complete system cleaning - this maintains engine health, extends lifespan, and saves money long-term.
