How to Determine if a Car is Burning Engine Oil?

[LeCharles]

Methods to determine if a car is burning engine oil are as follows: 1. The oil dipstick is significantly below the minimum level; 2. The exhaust pipe has noticeable carbon particles that feel sticky to the touch, and the exhaust emits blue smoke; 3. Opening the oil filler cap or checking the oil dipstick reveals significant exhaust gas or even blue smoke; 4. Removing the spark plugs shows obvious carbon buildup and traces of engine oil; 5. An endoscope inspection reveals significant carbon deposits in the valve guides and combustion chambers; 6. The catalytic converter has noticeable carbon buildup. The reasons for a car burning engine oil are: 1. A fault in the design of the crankcase forced ventilation system; 2. The presence of crosshatch patterns on the cylinder walls. The hazards of burning engine oil include: generating large amounts of carbon deposits and gum, leading to increased fuel consumption and reduced engine power, and potentially causing difficulty in starting the engine, resulting in severe engine wear.
