What to Do If the Car is Burning Engine Oil?

Automobile burning engine oil solution is to repair the engine, clean the carbon deposits inside the engine, replace damaged parts, replace the valve oil seals, etc.; if the situation is more serious, the engine needs to be overhauled. When encountering the phenomenon of burning engine oil, it should be dealt with in time. Below is an introduction to the causes of automobile burning engine oil: 1. Poor valve sealing: The valve is to prevent engine oil from leaking into the combustion chamber, but with the increase of service life, wear and aging will occur, making the valve sealing poor, allowing engine oil to easily enter the combustion chamber. 2. Increased piston clearance: After long-term operation, carbon deposits will be generated at the piston part, and there will also be a certain degree of wear. As time goes by, the piston clearance continues to increase, and engine oil is more likely to enter the combustion chamber. 3. The viscosity of the engine oil is too small: If the viscosity of the engine oil used is too small, the phenomenon of burning engine oil will also occur. When the viscosity of the engine oil is too small, it has good fluidity and is easy to enter the cylinder, thereby participating in combustion; 4. Excessive engine oil: Excessive engine oil pressure will press part of the engine oil into the cylinder, resulting in the phenomenon of burning engine oil.

I've driven quite a few cars, and oil burning can be a minor or major issue. First, regularly check the dipstick to monitor consumption rate. Generally, consuming less than half a liter per 1,000 km is normal; anything beyond that warrants attention. If you see blue smoke from the exhaust, that's definitely oil burning. The most common causes are aging valve stem seals leaking oil or worn piston rings allowing oil into the combustion chamber. Older cars are more prone to this issue, so it's recommended to inspect engine seals around 80,000 km. Don't skimp on oil changes—use reputable full-synthetic brands, and regular carbon deposit cleaning helps too. If you notice severe consumption, immediately visit a repair shop for cylinder pressure tests—never wait until engine seizure occurs.

Don't panic if you find your car burning engine oil. I've dealt with similar situations myself. First, use an oil pressure tester to check the readings and see if they're within the normal range. Focus on inspecting three key areas: whether the valve seals have cracks, the elasticity of the piston rings, and the condition of the turbocharger's sealing rings. Also, pay attention to the PCV valve (Positive Crankcase Ventilation valve), as a blockage can cause oil to be sucked back into the intake pipe. For daily maintenance, it's recommended to shorten the oil change interval, such as changing the oil and oil filter every 5,000 kilometers. As a temporary solution, you can add some oil additives, but for severe cases, it's best to replace the engine's internal seals. Remember, long-term oil burning can clog the catalytic converter, leading to more expensive repairs.

My car also used to burn oil, and I've summarized some practical tips. First, record the oil consumption after driving 1,000 kilometers following an oil change. If it exceeds 300 milliliters, it's time to pay attention. The check is simple: when the engine is cold, pull out the dipstick, wipe it clean, reinsert it, and confirm the oil level. Then, check the inner wall of the exhaust pipe for black sludge. Minor oil burning can be managed by switching to a higher viscosity oil temporarily or adding a specialized repair additive. If the engine runs smoothly without unusual noises, the issue is likely with the valve stem seals, which can be replaced without disassembly. However, if the piston rings are the problem, a major engine overhaul is required, and you'll need to consider whether the car's age justifies the repair. Regular oil changes are crucial—never exceed the recommended mileage.
