What kind of engine oil should be used for the maintenance of the Yuexiang V3?
1 Answers
The recommended engine oil for the Yuexiang V3 maintenance is 5W-30, with Mobil being the brand of choice. Alternatively, you can also opt for engine oils from brands like Shell or Castrol for maintenance. 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. A higher value means the oil can maintain its viscosity index better 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 Yuexiang V3 is as follows: Wait for the engine temperature to drop, and also allow the engine oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath 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 some engine oil to the oil seal of the new oil filter and tighten it clockwise by hand; Pour the new engine oil into the engine through the oil filler cap on the valve cover. Generally, about three-quarters of a bottle of oil is sufficient; 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 there are any leaks, they should be repaired; After stopping the engine, pull out the oil dipstick to check if the engine oil level is within the standard range.
