Why does my Honda City produce blue smoke from the exhaust, and is it related to oil burning?

If a Honda City starts emitting blue smoke, it’s often a sign of oil burning inside the engine. What are the possible reasons for this issue, and does it indicate a serious problem like failing piston rings o r valve seals?

Blue smoke from the exhaust is a clear indication that your Honda City is burning oil. This is typically caused by worn-out piston rings o r valve seals, which allow oil to leak into the combustion chamber. When this happens, the oil gets burned along with the fuel, leading to blue smoke. If you notice blue smoke, it’s a sign of internal engine wear, and it’s usually an indication that the piston rings o r valve seals need attention o r replacement.
