What Does Colorful Exhaust Mean?

There are many ways to tell if your vehicle is having trouble operating, such as a dashboard indicator light, a weird shaking sensation, strange noises or perhaps a visual clue. Because your senses are able to detect potential issues with your vehicle’s various systems that a computer cannot, it is always important to pay attention to what your car may be trying to tell you. One of the most common signs of engine trouble can be detected with your eyes, which is spotting an increased amount of exhaust smoke. Depending on the color of the smoke, you can get a general idea of what the issue may be. These are the three common colors of exhaust smoke you will encounter if trouble is present, here’s what they mean.

Black exhaust smoke

If your vehicle is spewing black exhaust it means that the motor is burning excessive amounts of gasoline. This can be caused by several issues, but most notably it could be due to a leaking fuel injection system. However, there is another common problem that is very simple to fix. If the air filter becomes clogged it will deny the engine of the correct air/fuel mixture it needs to properly operate. Since there is a decrease in airflow, the motor will compensate by burning additional gasoline. This is not only going to wreak havoc on your miles per gallon but it could cause additional problems inside the motor due to increased operating temperatures. Be sure to visit an auto repair shop as soon as possible to have your air filter replaced to restore engine function.

White exhaust smoke

White clouds of exhaust smoke generally indicate an internal cooling system leak, as this is the result of burning coolant. If your engine is leaking coolant into the combustion chamber it puts your car at risk of overheating, which can lead to numerous other problems for your engine, such as a blown head gasket. Cooling system leaks will often be accompanied by a very sweet smell.

Blue exhaust smoke

Oil is the lifeblood of the engine. Without it, the motor will quickly seize up due to harsh friction between the moving parts that are inside of it. For this reason it is important to head to the auto repair shop if you notice your vehicle producing blue exhaust smoke, as this is the color of smoke produced by burning oil.

Excessive exhaust smoke is one of many ways to tell if your car is in need of service. If you ever suspect car trouble get to a repair shop for diagnostics immediately, as problems will only get worse.
