What kind of engine oil is suitable for Haval H6?
3 Answers
The original factory engine oil brand for Haval H6 is SL-grade 10W-40 oil from French company Total. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, or Total. The oil models recommended in the official Haval H6 manual are 10W-40 and 15W-40. Any oil model that meets these two specifications 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, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, 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 oil in Haval H6 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 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; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover filler port, generally filling up to three-quarters of the oil container; 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 leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
I drive a third-generation Haval H6 1.5T, and the 4S shop has always used 5W-30 full synthetic oil for me. The manual also clearly recommends this specification. Using full synthetic oil in turbocharged cars is indeed more stable, provides better high-temperature protection, and reduces turbocharger carbon buildup. I've tried Mobil, Shell, and Great Wall's original gold series, and they all run very smoothly, with noticeably less engine noise. Especially when climbing hills with the AC on in summer, the power doesn't falter even when the RPM reaches 4000. I recommend not skimping on mineral oil; full synthetic oil can last 8000-10000 kilometers between changes, which actually works out to be more cost-effective and provides better engine protection.
Frequent long-distance 2.0T drivers should check this out. For the GW4N20 engine in Haval H6, low-viscosity full synthetic oils like 5W-30 or 0W-30 are more suitable, especially for stop-and-go city driving conditions. I've tested 0W-30 and found it provides faster cold starts, making ignition much smoother in winter temperatures below -10°C. Look for ACEA C2/C3 or SP-grade certifications to ensure sufficient high-temperature shear resistance for turbo protection. A quick reminder: If you drive aggressively, check the oil condition every 6,000 km as turbocharged engines are prone to sludge buildup. Last service I switched to ester-based full synthetic oil, and throttle response improved noticeably.
