What are the reasons for oil burning in the 2015 Haval H9?

Here are the reasons for oil burning in the 2015 Haval H9: Poor fuel quality: The primary cause of oil burning in vehicles is poor fuel quality. When fuel does not burn completely, it generates 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 oil to enter the combustion chamber and burn, resulting in oil burning. Incomplete fuel combustion: Due to traffic congestion, especially for city-driving vehicles that frequently stop and start, fuel does not burn efficiently, leading to significant carbon deposits. These deposits block 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 oil burning.
