What is the oil specification for Haval H4?
2 Answers
Haval H4 uses fully synthetic oil with the specification 5W30. The oil should be filled up to just below the maximum mark on the dipstick (AB represents the maximum and minimum marks on the dipstick). Below is an introduction to the Haval H4 oil specifications: 1. 5W30 refers to the SAE standard viscosity value, which indicates that this oil is a multi-grade oil. 2. W stands for WINTER, and the number before W represents the oil's flow performance at low temperatures. The smaller the number, the better the starting performance at low temperatures. The number after W represents the oil's stability at high temperatures. The larger the number, the better the oil's stability at high temperatures. 3. The smaller the number before W, the lower the oil's viscosity at low temperatures, the better its low-temperature fluidity, and the lower the minimum applicable temperature.
I've been driving my Haval H4 for over three years, always using 5W-30 full synthetic oil. The manual clearly recommends this viscosity, especially for the turbocharged version. Last time during maintenance at the 4S shop, the technician explained that the number 5 before W represents low-temperature fluidity (no problem at -30°C), and 30 refers to high-temperature viscosity protecting the engine. Choosing the right oil is particularly important. Even in northern winters at -20°C, cold starts remain smooth, and there's no oil overheating during summer long-distance drives. Remember to select oils with ACEA A5/B5 or API SP certification, like Shell Helix Ultra from major brands, for greater peace of mind.
