What is the solution for engine oil burning in cars?
2 Answers
Engine oil burning in cars can be addressed as follows: 1. If the car burns oil when cold but returns to normal after warming up, this phenomenon is caused by aging valve stem seals. Solution: Remove the engine cylinder head and replace the valve stem seals. 2. If the car continues to emit blue smoke from the exhaust pipe after reaching normal operating temperature, this indicates poor sealing of the piston rings. Solution: Remove the oil pan and replace the piston rings. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Minimizing gas leakage and preventing contamination from external sources; 3. Protecting components from contact with water, air, and harmful acidic gases; 4. Cushioning the pressure rise at the engine cylinder ports; 5. Flushing away dirt generated on the working surfaces of components.
I often encounter the issue of oil burning, and solving it requires a step-by-step approach. First, check if the engine seals are damaged, such as leaks from the valve cover gasket or oil pan. If there's a leak, replacing the gasket can fix it—cheap and simple. If it's an internal issue like worn piston rings or scratched cylinder walls, then an engine overhaul is needed, involving new rings or cylinder repair, which might cost a few thousand but can eliminate the problem completely. Burning oil causes blue smoke from the exhaust, damaging the catalytic converter, so I recommend regular oil level checks and maintaining proper levels. Using higher viscosity oil can also reduce consumption. A temporary fix is adding oil additives, which can fill small gaps and reduce burning—I've found them effective but not a long-term solution. Avoid prolonged high-speed driving to reduce engine stress and prevent issues. If unsure, visit a professional repair shop for a thorough inspection—don't cut corners and risk bigger expenses. Safe driving comes first.
