What type of engine oil is used in the Great Wall Pao diesel version?
2 Answers
The Great Wall Pao diesel version uses engine oil with the specification 5W-40. Engine oil, also known as motor lubricant, serves multiple functions such as lubrication to reduce friction, assisting in cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. Usage scenarios for different engine oil specifications: High-temperature types for summer use: 20, 30, 40, 50. The larger the number, the higher the viscosity, and the higher the maximum applicable temperature. Low-temperature types for winter use: 0W, 5W, 10W, 15W, 20W, 25W. The 'W' stands for Winter, and the smaller the number before 'W,' the lower the low-temperature viscosity and the better the low-temperature fluidity, making it suitable for lower minimum temperatures. All-season types for both winter and summer use: 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, etc. The smaller the number before 'W,' the lower the minimum applicable temperature, and the larger the number after the hyphen, the higher the maximum applicable temperature.
I've been driving diesel vehicles for many years, including the Great Wall Pao diesel version. This vehicle works best with 5W-30 full synthetic oil. Diesel engines run at higher temperatures and require greater oil pressure. 5W-30 flows quickly during cold starts, protecting the engine from wear, and remains stable without thinning at high temperatures. I change it approximately every 8,000 kilometers. Combined with cleaning formulas from reputable brands like Shell, it can reduce carbon buildup and improve fuel efficiency. Remember to regularly check the oil dipstick, especially before long trips. Long-term neglect can lead to increased engine noise, higher fuel consumption, and even cylinder damage. In winter, use thinner oil to prevent freezing, and avoid overly thick oil in summer. The manual specifies 5W-30 as the standard—following it is the safest approach. When changing the oil, also check the filter to ensure everything runs smoothly.
