Noticing unusual smoke from your vehicle’s exhaust? Different colors can point to specific issues under the hood:

Blue smoke: Oil is burning, likely due to worn piston rings or valve seals.

White smoke: Thick white smoke can mean coolant is leaking into the engine, signaling a possible blown head gasket or cracked engine block.

Black smoke: Too much fuel is being burned, often caused by a clogged air filter, fuel injector issues, or a faulty sensor.
