What is the recommended engine oil specification for the BYD F3 maintenance manual?
2 Answers
BYD F3 maintenance manual recommends using 10W-30SG engine oil. Introduction to BYD F3 engine oil selection is as follows: 1. Engine oil is an important factor affecting engine performance and service life. The BYD F3 is factory-filled with high-quality multi-viscosity oil, specifically 10W-30SG, which can be used year-round except in extremely cold climates. 2. The principle for purchasing engine oil is "there is no best, only the most suitable oil." It is first recommended to use the model recommended by the vehicle manufacturer. When purchasing engine oil, be sure to select the corresponding specification. As for the oil viscosity grade, simply follow the manufacturer's recommendations. 3. If the manufacturer does not specify otherwise, you can refer to the driving environment to choose engine oil. Generally speaking, commonly available oils such as 0W-40, 5W-30, and 5W-40 have strong applicability and can suit most climate conditions in China and the usage requirements of most vehicles.
I've driven several BYD F3s, and the maintenance manual recommends 5W-30 oil, which is the most common choice suitable for all-season driving. If you live in a cold region, it ensures smoother starts in winter; it also maintains good lubrication under high summer temperatures. However, I must remind you that the oil type isn’t fixed—it depends on the vehicle’s year and engine type. With years of repair experience, I’ve seen many car owners face issues from using the wrong oil—like thicker 10W-40, which increases fuel consumption and accelerates engine wear. So, sticking to the manual’s recommended SL or SM grade is key. Oil change frequency matters too: the BYD F3 manual suggests checking every 7,500 km. Avoid cheap aftermarket products to prevent clogged oil passages or reduced engine lifespan. Regular oil changes save hassle and ensure safety, especially on long trips—you’ll appreciate it then.
