Does the 3rd Generation Haval H6 Burn Engine Oil?
3 Answers
Haval H6 3rd Generation burns engine oil. Burning engine oil refers to the phenomenon where engine oil enters the combustion chamber of the engine through certain pathways and participates in combustion along with the air-fuel mixture. Poor Fuel Quality: The primary cause of engine oil burning is poor fuel quality. When fuel cannot be fully combusted, it forms a large amount of carbon deposits. Over time, these deposits accumulate and thicken, with some entering the piston, causing piston ring sticking and clogging the oil return holes. This creates gaps in the engine, allowing air to enter the combustion chamber and participate in combustion, leading to the burning of engine oil. Traffic Congestion: Due to traffic congestion, fuel cannot be effectively combusted, generating a large amount of carbon deposits. These deposits clog the oil return holes, preventing the oil scraper ring from removing oil from the cylinder walls. As a result, the oil remains in the combustion chamber and burns, causing the engine oil to burn. Aging Valve Stem Seals: Aging valve stem seals can also lead to engine oil burning. Valve stem seals are made of heat-resistant and oil-resistant rubber. These seals are exposed to high temperatures and come into contact with gasoline and engine oil, along with temperature fluctuations from cold and hot operations. Over time, the plasticizers in the seals are depleted, causing the seals to shrink. This allows engine oil to enter the combustion chamber and burn, resulting in the burning of engine oil. Substandard Engine Oil Quality: Substandard engine oil quality is another reason for engine oil burning. If the oil quality is substandard, its lubricating effect weakens. Combined with the accumulation of carbon deposits, the oil loses its lubricating properties, making it easier to cause wear on the cylinder walls. This wear increases the engine temperature, quickly leading to cylinder scoring and engine failure.
I've been driving the Haval H6 3rd generation for over a year now, and overall it feels quite reliable. But when it comes to oil consumption, I need to be honest. I've heard from other owners that the GW4B15 engine in this model may have slight oil consumption under certain conditions, such as during long-distance high-speed driving or in hot weather, but this isn't a universal issue. My car hasn't experienced anything severe, just occasionally showing a slight drop on the dipstick. The reasons could be aging piston ring seals or impurities in the oil passages. I recommend making it a habit to check the oil level every two weeks. If you notice it decreasing quickly, try switching to full synthetic oil, which is more resistant to high-temperature wear. Make sure to change the oil and filter on time during maintenance, and don't delay it too long. Try to drive smoothly in daily use and avoid aggressive acceleration. Overall, this car offers great value for money, and the chance of oil burning is low, but it doesn't hurt to stay vigilant.
As someone who frequently repairs cars, I've encountered many Haval H6 third-generation owners. Oil burning does occur, but the proportion is not high, mostly concentrated in certain batches of the GW4B15 engine. Common causes include loose oil seals, piston ring wear, or PCV valve issues, leading to increased oil consumption during high-speed operation. I recommend owners first conduct a self-check: after warming up the engine, wait 10 minutes and check the dipstick; if the oil level drops significantly, it's time to visit the shop for inspection. Using high-quality 5W-30 oil can improve sealing, and performing maintenance every 5,000 kilometers helps avoid carbon buildup. Prevention is better than repair—reducing sudden acceleration habits protects the engine. Overall, this car has stable quality, and early detection of issues makes them easy to resolve, so there's no need to worry too much.
