What causes blue smoke on acceleration?
Blue Smoke From Exhaust When Accelerating When blue smoke is emitted from a car’s exhaust pipe, this usually indicates that a leak in the engine’s valve seals is allowing oil to leak into the combustion chamber where it is being burned along with the fuel. This may be due to natural deterioration or a faulty part.

These seals prevent oil from leaking down the valve stems into the combustion chambers. As the vehicle sits after being operated, oil accumulates in the cylinders, and when the engine is restarted later, the accumulated oil burns off. Thicker oil may not stop smoking at startup. It could; but not always.
