What are the consequences of engine oil burning in cars?
3 Answers
Engine oil burning in cars can lead to: 1. Rapid damage to the vehicle's oxygen sensor; 2. Increased fuel consumption, excessive exhaust emissions, unstable idling, heightened vehicle hazards, and increased economic burden; 3. Increased carbon deposits in the engine combustion chamber, reduced acceleration, sluggish speed, and insufficient power; 4. Insufficient engine lubrication, causing irreparable damage to the engine until it is scrapped, significantly increasing repair costs and accident risks. The causes of engine oil burning are: 1. Use of poor-quality oil or oil with an inappropriate viscosity grade; 2. Excessive clearance between the piston rings and cylinder wall, improper installation of piston rings, or poor sealing, allowing oil on the cylinder wall to enter the combustion chamber; 3. Overfilling of engine oil; 4. Oil leaks from the turbocharger and valve seals.
My old car once had severe oil burning issues, with the exhaust pipe constantly emitting blue smoke on the road, leaving the whole car smelling burnt. After the spark plugs got clogged with oil residue, ignition problems arose, and the engine would frequently shake, making the car drive like it was staggering. The engine oil consumption was rapid, requiring a top-up every half month, costing extra money. What's more frustrating was the weak power output, struggling even on uphill climbs. Prolonged neglect would accelerate wear on internal engine components like piston rings and cylinders, with repairs easily costing thousands. Not to mention the environmental pollution—I was once fined for excessive exhaust emissions. I realized I couldn't delay any longer and promptly sought professional inspection to avoid a complete breakdown.
Experience tells me that burning oil is a common aging issue. Once oil seeps into the combustion chamber, blue smoke comes out of the exhaust pipe, and the spark plugs get oily, causing delayed ignition. You'll notice the engine runs louder and acceleration becomes sluggish when driving. Fuel consumption increases, hitting your wallet hard. If ignored, insufficient lubrication accelerates part wear and may even lead to cylinder seizure. A car enthusiast I know had to repair his engine because of this. I recommend regularly checking the dipstick and addressing issues early to stay safe.
