Oil burning in an engine can happen due to several reasons. Worn piston rings allow oil to mix with the air-fuel mixture in the combustion chamber. Degraded valve seals and guides can also permit oil entry into combustion.Malfunctioning PCV valves may draw excess oil vapor into the intake manifold.Poor maintenance habits like infrequent oil changes or using the wrong viscosity oil can lead to oil degradation. Overfilling the oil reservoir can force oil into undesired places, causing burning. This not only decreases lubrication efficiency but also causes issues like fouled spark plugs, decreased performance, and harmful emissions. Regular maintenance, including replacing worn components, using the correct oil, and addressing leaks promptly, is crucial to prevent this problem and ensure engine longevity and efficiency.
