What is the cause of a lantra blowing blue smoke from the exhaust?

Blue smoke from the exhaust of a Hyundai Lantra typically indicates that the engine is burning oil. This can be caused by worn piston rings, valve seals, or other internal engine components that allow oil to enter the combustion chamber. Additionally, issues with the turbocharger, if equipped, could also lead to oil leakage and blue smoke. Addressing the underlying cause is essential to prevent further engine damage.
