What kind of engine oil does the Haval H2S use?

Haval H2S's original factory engine oil brand is Total. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, or Castrol. The recommended oil specification for the Haval H2S in the official manual is 5W-30. Any oil that meets this specification can be used. 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. The second number represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain its viscosity 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 a Haval H2S is as follows: Wait for the engine temperature to drop, which also allows 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 30 seconds to allow the oil in the main oil passage to drain out. Use a specialized wrench to remove the oil filter. Apply some oil to the gasket of the new oil filter and tighten it clockwise by hand. Add the new oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a standard oil container. Start the engine and let it run for 5 minutes, then check for leaks around the oil drain plug and oil filter. If there are any leaks, perform necessary repairs. After stopping the engine, pull out the dipstick to check that the oil level is within the standard range.
My family drives a Haval H2S, and I specifically checked the manual when changing the oil last year. The manufacturer recommends using 5W-30 full synthetic oil, especially paying attention to low-temperature fluidity in northern winters. During the last maintenance, I used Shell Helix Ultra, and the engine noise was noticeably reduced. Remember, never skimp by using mineral oil—this car's engine has high precision and requires full synthetic for proper protection. I usually change the oil around 8,000 kilometers, especially since I often drive on rough suburban roads. If I take more long trips in the summer, I’ll even change it at 7,000 kilometers because oil degrades faster in high temperatures. As a side tip, always ask the mechanic to check the oil filter during an oil change—once, I had a leaking filter and wasted fresh oil for nothing.
Just helped my cousin with maintenance on his Haval H2S a couple of days ago, and specifically researched engine oil issues. This car recommends using 5W-30 synthetic oil. I've tried Castrol Magnetec and Mobil 1, both worked well. The key is to look for API SN or higher certification, though SM grade is acceptable for older models. Once a repair shop recommended 0W-40, but it actually worsened cold start protection in winter. Pay special attention to viscosity for high-mileage cars - my neighbor's 100,000 km H2S experienced soaring fuel consumption after switching to 40 viscosity. Also, a reminder about oil change intervals: 7,000 km for city driving, can stretch to 9,000 km with more highway use. Never believe those who say wait until 15,000 km - our domestic car engines require more attentive maintenance.
