Does the Mercedes-Benz G350 burn oil?
2 Answers
Mercedes-Benz G350 does not burn oil. Valve oil seal: The valve is actually used to prevent oil from leaking into the combustion chamber, but over time, some wear or aging will inevitably occur. Severe cases can affect the sealing of the valve, making it easy for oil burning to occur. Therefore, if there is an issue with the valve oil seal, it should be replaced promptly. Excessive piston clearance: When a car is used for a long time, carbon deposits from incomplete combustion will adhere to the piston rings. If not cleaned for an extended period, it may cause the gap between the piston rings and the cylinder to expand, allowing oil to flow into the combustion chamber and resulting in oil burning. In severe cases, it can even lead to engine "seizure." Therefore, regular carbon cleaning is very important and an effective way to prevent oil burning. Driving habits: Frequent sudden acceleration and prolonged high-speed driving (high engine speed) can easily damage the lubricating oil film, leading to poor engine lubrication and wear on certain parts, with a certain probability of oil burning. Therefore, in daily driving, pay attention to your driving habits and avoid aggressive driving.
As an experienced mechanic, I've worked on many Mercedes-Benz G350 models, and indeed, some of them experience excessive oil consumption, especially the diesel versions with over 100,000 kilometers on the odometer. Burning oil means the engine consumes too much oil, which can be caused by worn piston rings, aging valve seals, or the use of inappropriate engine oil. It's less common in new vehicles, but as mileage accumulates, improper maintenance like delayed oil changes can lead to this issue. I've seen blue smoke from the exhaust pipe as a clear sign, and the acceleration may also feel sluggish. I recommend owners check the oil dipstick monthly. If they notice oil consumption exceeding the normal range, it's best not to delay and have the engine internals inspected by a professional shop promptly. Ignoring it could damage the catalytic converter or reduce engine lifespan, increasing repair costs. Overall, the G350 is quite reliable, but regular maintenance is key to preventing oil burning issues.
