What type of oil does the Baojun 510 use?
1 Answers
The original factory oil specification for the Baojun 510 is SM/GF-4 5w-30. According to the official maintenance manual, the Baojun 510 requires SM-grade oil with a viscosity rating of 5w-30. The viscosity of engine oil changes with temperature, so it's important to pay special attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The second number represents the oil's kinematic viscosity at 100°C. A higher number means the oil can maintain its viscosity better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Baojun 510 is as follows: Wait for the engine temperature to cool down, allowing the oil to drain back into the oil pan; Use a wrench to loosen the drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine for about 30 seconds to allow the oil in the main oil passages to drain out; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the engine valve cover's oil filler port, typically filling about three-quarters of a standard oil container; Start the engine and let it run for 5 minutes, checking for leaks around the drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the dipstick to check that the oil level is within the standard range.
