What are the symptoms of a car burning oil?

The symptoms of a car burning oil include thick smoke when starting the car and blue smoke during acceleration. The specific symptoms are as follows: Thick smoke when starting the car: If the car is burning oil, thick smoke may appear when starting the car after it has been parked for a long time. This phenomenon is particularly noticeable in the morning, with dense blue smoke visible from the exhaust pipe. If this occurs, it is important to pay close attention and check whether the car's oil level is normal. Blue smoke during acceleration: Similarly, due to the intense burning of oil, the color of the exhaust gas may become abnormal. When the accelerator is pressed hard or during rapid acceleration, large amounts of blue smoke may be emitted from the tailpipe, even visible through the rearview mirror. If this happens, it indicates that the oil burning is already quite severe, and the car should be taken to a 4S shop for repairs as soon as possible to avoid accidents.
Last year while driving, I noticed my car was burning oil with obvious symptoms: thick blue smoke billowing from the exhaust pipe during acceleration, resembling burning plastic with a distinct burnt smell; the oil consumption became alarmingly fast - while I previously only needed to top up every 5,000 km, now the dipstick would drop to the minimum mark after just 1,000 km, forcing me to spend money on oil supplements monthly; upon inspecting the spark plugs, they were completely covered in black carbon deposits, which the mechanic identified as signs of oil mixing into and burning in the cylinders; the engine also lost power, struggling even on small inclines while fuel consumption increased significantly. An experienced mechanic suggested it might be worn piston rings or leaking valve guides, warning that the entire engine could be ruined if not repaired promptly. I eventually spent over 2,000 yuan fixing the piston rings to resolve the issue. Developing a regular habit of checking the dipstick can help detect such warning signs early.
