05 teana 350jm engine oil,

The reasons for burning engine oil can be understood as follows:

1. Domestic oil products (including gasoline and engine oil) 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. The valve oil seal and crankshaft oil seal are corroded and aged, resulting in oil leakage.
