What Type of Oil Should Be Used for BYD Song?
1 Answers
The original oil is the oil used for BYD Song, with the oil model being 5W-40. In terms of applicability, the original oil is more suitable for the engine. However, depending on different needs, oil can also have other benefits, such as noise reduction, fuel efficiency, and performance enhancement. Therefore, you can also choose oils from brands like Mobil, Shell, and Castrol. The viscosity of oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better the oil can maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in BYD Song is as follows: Wait for the engine temperature to drop and allow the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out. Use a special wrench to remove the oil filter. Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add new oil through the oil filler cap on the engine valve cover, usually filling up to three-quarters of the oil container. Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made. After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
