Does Haval consume a lot of engine oil?
2 Answers
Haval vehicles may initially experience some engine oil consumption, but it is not very noticeable. The oil burning phenomenon tends to become more severe only after reaching 100,000 kilometers. Inferior engine oil quality: Low-grade engine oil can accelerate wear and tear. Additionally, engine oil with viscosity that is either too low or too high can lead to poor lubrication, increasing wear on piston rings and cylinder walls, reducing sealing performance, and resulting in oil burning. Excessive clearance: Excessive clearance between piston rings and cylinder walls, improper installation of piston rings, or deteriorated sealing can allow oil from the cylinder walls to enter the combustion chamber, causing oil burning.
I've driven a Haval H6 for three years and indeed encountered oil burning issues. The 2.0T engine was particularly noticeable on long trips, requiring 1 liter of oil top-up every 3,000 km. Not all Havals have this problem, but it was a common issue with Great Wall's early Mitsubishi-technology engines. A mechanic friend said it was mainly due to defective piston ring design and easily aging valve stem seals. Later, I had a major engine overhaul at a professional shop and replaced them with improved piston rings to finally solve it. The new 1.5T models are much better now - I'd recommend checking maintenance records for oil consumption when buying used Havals. If the oil light stays on, don't delay as it can easily cause cylinder scoring.
