Why do I see blue smoke from my Tiggo 4’s exhaust?

Blue smoke indicates that engine oil is burning inside the combustion chamber. This is often caused by worn piston rings, damaged valve seals, o r cylinder wall damage. If ignored, it can reduce engine efficiency, increase oil costs, and lead to long-term engine problems.
