Burning engine oil means that the engine oil rushes to the combustion chamber to burn. The reason can be understood as follows:

1. Oil problems are prone to carbon deposition.

2. Carbon deposition causes the piston ring to jam and lose its oil scraping performance; The oil return hole is blocked and the oil cannot flow back to the crankcase normally.

3. Wear between the cylinder wall and the piston, and the gap is too large.

4. Corrosion and aging of valve oil seal and crankshaft oil seal lead to oil leakage.

This is the main reason for burning engine oil, and most car owners have it.

The secondary consequences of burning engine oil are increased fuel consumption, insufficient power, blue smoke and substandard tail gas. The serious consequence is that the engine is scrapped.
