What Type of Engine Oil Should Be Used for the Great Wall Pao?
2 Answers
The original engine oil used for the Great Wall Pao is of the type 5W-30. In terms of suitability, the original oil is more compatible with the engine. However, depending on different needs, engine oils can offer additional benefits such as noise reduction, fuel efficiency, and enhanced performance. Therefore, you can also choose engine oils from brands like Mobil, Shell, and Castrol. 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, making cold starts smoother for the vehicle. 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 under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Great Wall Pao 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 underneath to catch the old oil until it stops flowing. Start the engine and let it run for about 30 seconds to allow the oil in the main oil passages to drain out. Use a special wrench to remove the oil filter. Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new engine oil through the oil filler cap 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 leaks around the oil drain plug and oil filter. If there are leaks, they should be repaired. 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 Great Wall Pao pickup for several years and found that 5W-30 oil, especially the fully synthetic type, suits it best. Most Great Wall Pao models are equipped with 2.0T engines, and the manual recommends this grade because it flows well during cold starts, quickly lubricating engine components even in sub-zero winter temperatures to prevent wear. I use Shell or Mobil brands for regular city and suburban driving, changing the oil every 5,000 kilometers. The oil doesn't clump in summer heat, and the engine runs smoothly at high speeds. Avoid cheap mineral oils as they tend to cause carbon buildup and reduced power. Regularly check the dipstick to ensure oil levels are neither overfilled nor insufficient. Choosing the right oil can significantly extend your vehicle's lifespan.
