Most of the time, exhaust smoke from your car, should barely even be noticeable.
But, if a problem were to arise, then blue, white or black smoke could start to appear from the exhaust pipe.
The first step is to identify exactly, when the smoke is coming out of your car’s exhaust.
If it only appears when you are accelerating, that might indicate a different problem; than if it only appears when stationary, or is it constant, when the engine is running.
