What type of engine oil is suitable for Jinbei Haishi?
2 Answers
Jinbei Haishi uses 5W-30 semi-synthetic engine oil. For later maintenance and oil changes, you can choose fully synthetic oils from Shell or Mobil. The official manual recommends using 5W-30 engine oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperature conditions. 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, resulting in smoother cold starts for the vehicle. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value indicates better ability to maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in Jinbei Haishi is as follows: Wait for the engine temperature to drop, allowing the oil to flow back to the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. 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 engine oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new engine oil through the filler port on the engine valve cover, typically 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 to ensure the engine oil level is within the standard range.
I've been driving the Jinbei Haise for many years, and SAE 10W-30 engine oil works quite well. The Jinbei's engine is quite durable and doesn't require expensive oil. Semi-synthetic oil is sufficient, with regular changes every 5,000 kilometers or six months—don't exceed this interval, or the engine will wear out faster, leading to costly repairs. Choose reputable brands like Shell or Castrol for oil; avoid cheap, unknown brands to extend engine life. In cold weather, the 10W-30 viscosity is just right, providing good lubrication and fuel efficiency. Keep maintenance simple, develop a habit of regular oil changes, and the car will run longer and safer, especially giving peace of mind on long trips.
