The Color Of Your Exhaust Smoke Explained By Our Springfield Auto Shop

| By: Christian Brothers Automotive

Our specialists explain what the color of your exhaust smoke indicates depending on the engine in your vehicle. So what does the color of your exhaust smoke mean?

If your vehicle has a diesel engine

While diesel and gasoline engines are similar, there are a few key differences. The combustion process is slightly different (diesel engines don’t use spark plugs because the engine runs at a higher temperature), so your colored exhaust smoke could indicate a variety of issues.

Black or gray exhaust smoke

Gray or black exhaust smoke in a diesel engine could be indicate several problems:

· Wrong grade of fuel used

· Clogged air filter

· Improper timing

· Overheating engine

· Leaking oil

· Faulty injection system

White exhaust smoke

If your exhaust smoke is white, this is a reason for concern in a diesel engine vehicle. White exhaust smoke means fuel is not burning properly. This could mean:

· The engine is too cold

· Faulty injection system

· Incorrect timing

· The engine is overheating

Blue exhaust smoke

Blue exhaust smoke in a diesel vehicle could still mean oil is being burned, but it could also mean the engine oil is being atomized. This could be caused by:

· High engine oil levels

· Worn out piston rings

· Old valves or cylinders

If your car has a gasoline engine

If your car or truck has a gasoline engine, here are the common reasons the exhaust would release colorful smoke:

Black or gray exhaust smoke

If your exhaust smoke is black or gray, the engine isn’t burning fuel the right way. This could be caused by several factors:

· Leaking oil

· Malfunctioning fuel injector

· Clogged air filter

White exhaust smoke

Before you worry about white exhaust smoke, make sure it’s actually smoke and not steam. Steam is rarely indicative of a problem. However, thick white smoke could mean:

· The engine is too cold

· Leaking head gasket

· Cracked block or cylinder head

Blue exhaust smoke

Blue exhaust smoke from the tailpipe is most likely a result of the engine burning oil. This could be caused by:

· Oil leaking into the combustion chamber

· Worn piston rings

· Old valves or cylinders
