Here are the reasons for oil burning in the 2015 Haval H9: 1. Poor fuel quality: The primary cause of oil burning in vehicles is poor fuel quality. When fuel cannot be fully combusted, 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. 2. Incomplete fuel combustion: Due to traffic congestion, especially for vehicles driving in urban areas, frequent stops and starts prevent effective fuel combustion, leading to the formation of excessive 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.
