What Do the Colors of Engine Smoke Mean?
Cars with combustion engines emit byproducts, and the color of the smoke from the exhaust can reveal important information about engine health.
Black Smoke
Black smoke often indicates excessive fuel burning, typically due to a clogged air filter, malfunctioning fuel injector, or a vacuum leak. It can also signal a worn-out engine. Recognizing black smoke is crucial for taking timely action.
Blue Smoke
Blue smoke is less common and usually indicates oil mixing with gas during combustion. This suggests that engine oil is burning, often due to worn piston rings or valve seals. It may also point to serious issues like a blocked oil filter or engine damage.
Monitoring the color of your engine smoke is vital for maintaining vehicle health.
