Oil burning in engines is typically due to worn out parts or system malfunctions. resulting in oil entering the combustion chamber and igniting with the fuel. Common culprits include damaged piston rings. valve seals. or cylinder walls. all of which can cause oil leakage and evaporation during the combustion process. These issues can worsen over time due to high mileage or lack of proper maintenance. Regularly checking oil levels and keeping up with maintenance can help minimize oil burning. However. if your engine experiences severe oil burning. it is recommended that you seek professional evaluation to pinpoint the underlying problem and determine if repairs or replacement parts are necessary to restore efficiency and prevent further damage.
