Is Blue Smoke When Accelerating a Sign of Burning Oil?

[Herb]

Blue smoke when accelerating is indeed a sign of burning oil. Burning oil occurs when engine oil enters the combustion chamber and mixes with the fuel-air mixture, then gets expelled through the exhaust pipe. Upon contact with moisture in the air, it produces blue smoke. However, there could be other reasons for blue smoke emission: 1. Valve issues: Worn, damaged, or broken valve seals, or excessive clearance between valves and guides. 2. Blockage problems: Clogged air filters or restricted intake causing rich fuel mixture, drawing excessive oil into the combustion chamber. 3. Engine problems: Prolonged incorrect driving habits or overloading leading to premature engine aging and wear.
