What type of engine oil is used for the Changan Oshan X7?

[DiCooper]

The engine oil specification for the Changan Oshan X7 is 5W-30. The Changan Oshan X7 uses original brand engine oil. If you wish to change the oil during later maintenance, you can choose oil brands such as Shell, Mobil, Castrol, or Total. The viscosity of engine oil changes with temperature, so special attention should be paid 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, ensuring smoother cold starts for the car in low temperatures. The latter number represents the kinematic viscosity of the oil at 100°C. The higher this number, the better the oil can maintain its viscosity index at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Changan Oshan X7 is as follows: Wait for the engine temperature to drop, allowing 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 specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover filler port. Generally, fill about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the dipstick to check that the engine oil level is within the standard range.
