What are the hazards of long-term engine oil burning?

Hazards of long-term engine oil burning: 1. It will lead to increased carbon deposits inside the engine and damage the three-way catalytic converter of the car engine. 2. It affects the fuel consumption and power output of the engine. 3. If carbon deposits are in the combustion chamber, they will also increase the compression ratio of the combustion chamber, causing engine knocking. The following are solutions for engine oil burning: 1. For old vehicles, the piston seals may have aged, leading to reduced cylinder sealing. Using higher viscosity oil can improve sealing. 2. Oil burning caused by carbon deposits, piston ring blockage, or seal aging can only be resolved by disassembly, replacement, or major repairs. 3. Overfilling oil can also cause oil burning; excess oil can be extracted using tools like a syringe.
Long-term oil burning poses significant hazards. Insufficient lubrication due to reduced oil levels increases friction between piston rings and cylinder walls, accelerating wear and tear. Over time, this leads to louder engine noise and decreased power output. Carbon deposits accumulate in the combustion chamber, clogging fuel injectors and spark plugs, resulting in higher fuel consumption and increased pollutant emissions. The catalytic converter often gets clogged and damaged by oil components, and its replacement is extremely expensive. From my experience, neglecting this issue can quickly lead to engine failure, with repair costs running into tens of thousands. Therefore, it's essential to regularly check the oil dipstick and top up when needed to avoid major breakdowns and prevent being stranded on the road.
My car has been burning oil for several years, and it's really been a hassle. At first, the oil consumption was fast, and I had to add a bottle every one or two thousand kilometers, which was both costly and troublesome. Later, the engine struggled to accelerate, wheezed when going uphill, and the blue smoke annoyed the neighbors. The emissions were so high that it failed the annual inspection. When I took it for repairs, I found severe piston ring wear, and the fix cost me over ten thousand yuan. Long-term issues like this hurt the wallet and also affect the driving experience. Now, whenever I drive, I pay close attention to the oil level. The lesson of burning oil is profound, and I remind everyone not to underestimate this issue—get maintenance done early to prevent problems.
