What kind of engine oil does the Haval H6 use?
5 Answers
The Haval H6 uses 10w40 viscosity semi-synthetic engine oil. The functions of engine oil are: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning; 4. Shock absorption; 5. Rust and corrosion prevention. The Haval H6 is a compact 5-door, 5-seat SUV with body dimensions of: length 4653mm, width 1886mm, height 1730mm, and a wheelbase of 2738mm. The Haval H6 is equipped with a 2.0T turbocharged engine and a 7-speed dual-clutch transmission, delivering a maximum power of 155 kW and a maximum torque of 325 Nm. It features front-wheel drive, with a front suspension using MacPherson independent suspension and a rear suspension using multi-link independent suspension.
My Haval H6 has run over 50,000 kilometers in three years, always using 5W-30 full synthetic oil. The 4S technician told me this viscosity is perfect for the 1.5T engine - quick cold starts in winter and sufficient high-temperature protection in summer. For stop-and-go city driving conditions like ours, full synthetic holds up better than mineral oil, allowing maintenance intervals of 8,000 to 10,000 km. Last year I switched to Shell and noticeably felt quicker throttle response with about half a liter lower fuel consumption. But for owners of older naturally aspirated engines, semi-synthetic is cost-effective enough. The key to choosing oil is following the manual's requirements - never mix different brands randomly.
With over a decade of experience in auto repair, I've handled at least a hundred Haval H6s. The factory maintenance manual clearly specifies using API SN or higher-grade 5W-30 engine oil, especially for turbocharged third-generation models. What worries me most is when owners use high-viscosity oil improperly. While 40-viscosity oil can work in a pinch, it increases fuel consumption and its poor low-temperature fluidity can lead to engine wear. In practice, I've found Great Wall Lubricant's J700 series fully synthetic oil offers great value for money, costing just over 200 yuan. For owners who frequently drive long distances, I recommend changing the oil every 8,000 kilometers. Those who mainly drive short distances should shorten the interval to every six months.
When I first got my hands on the new H6 hybrid, I specifically researched engine oil. The factory now recommends 0W-20 low-viscosity oil, specifically designed for the hybrid system's frequent start-stop characteristics. I compared the factory oil with the commonly available Shell Helix Ultra, and the latter indeed offers better quietness when the electric motor kicks in. Owners of regular fuel-powered versions, take note: the 1.5GDIT engine must use SP-grade full synthetic oil—mineral oil simply can't withstand the high-pressure environment of direct injection. Last week, while helping a friend service an older H6, the 2017 model actually ran more smoothly with 5W-40. In short, always check the engine model before buying engine oil.
Over the years of running an auto parts store, the most frequent question from Haval owners is about engine oil. For the third-generation H6, 5W-30 is the most commonly used. It's recommended to choose a full synthetic oil with ACEA A5B5 standards, such as Mobil ESP, which comes with environmental certifications and is particularly suitable for China VI vehicles. There's a common misconception to clarify: more expensive doesn't always mean better—the key is to look for certification labels. I've personally seen customers opt for cheap, counterfeit oil, leading to sludge buildup in just 5,000 kilometers. Turbocharged engines are most vulnerable to oil film failure, and full synthetic oils offer three times the shear resistance of mineral oils. If you're changing the oil yourself, remember to replace the oil filter simultaneously—the Mann W7012 model is especially compatible with the H6's filter housing.
