Does the Haval H6 consume engine oil?
4 Answers
Haval H6 consumes engine oil, but it is not very serious. Main reasons for oil consumption: Excessive wear of engine piston rings, poor sealing of valve oil seals, and faults in the exhaust gas recirculation system. Solutions for Haval H6 oil consumption: Replace the exhaust valve, which is the key component causing oil consumption in the H6. Engine introduction: The car's engine has a crankcase forced ventilation system. When the engine is running, some gases enter the crankcase through the piston rings. An increase in gases inside the crankcase leads to higher pressure, making it difficult for the piston to move downward and affecting engine performance.
As a long-time Haval H6 owner, I've been driving the third-generation model for over two years without any oil burning issues. However, some owners of older 1.5T models, especially those with pre-2017 engines, have reported this problem. The current GW4B15 engine has improved piston rings, keeping oil consumption within normal range - the manual states consumption up to 0.3L per 1,000km is normal. Watch for three warning signs: blue smoke from exhaust during cold starts, oil dipstick reaching minimum level within two weeks, or noticeable oil shortage at 5,000km maintenance. If observed, immediately check valve stem seals and cylinder wall wear. My neighbor's second-gen H6 with 150,000km had stuck piston rings causing oil burning, costing over 5,000 yuan for major repairs. Always use low-ash 5W-30 full synthetic oil - this car is quite particular about engine oil.
From a repair shop perspective, the oil burning issue with the Haval H6 is primarily concentrated in the second-generation 1.5T engines. Last week, we serviced a 2015 model that was burning 0.8 liters per 1,000 kilometers. Upon disassembling the engine, we found the oil-gas separator had failed, allowing oil vapor from the mixture to enter the combustion chamber directly. The third-generation models show significant improvement, but high-mileage vehicles can still experience problems. It's crucial to check if the PCV valve is clogged, as a blocked valve increases crankcase pressure, forcing oil into the cylinders. During maintenance, remember to inspect the intake pipe behind the throttle body—oil stains there indicate an issue. We recommend cleaning the intake system every 30,000 kilometers and avoiding cheap mineral oils, as inferior oil is more prone to sludge buildup, which can seize piston rings.
As an automotive reviewer, I conducted real-world testing on the Haval H6's oil consumption across three generations. Over a continuous 5,000 km test, the oil level dropped from the maximum mark to the midpoint, consuming approximately 0.25 liters - significantly below China's national standard of 0.3 liters per 1,000 km. However, driving habits matter: frequent redline gear shifts or prolonged short-distance driving may prevent the engine from reaching optimal temperature, potentially causing oil residue in the combustion chamber. The new model's oil level sensor is particularly practical, with the dashboard actively issuing warnings. If you notice black oil sludge inside the exhaust pipe or oil film on the spark plug electrodes, these are typical signs of oil burning. I recommend opting for the new version with the manufacturer's lifetime engine warranty for long-term peace of mind.
