Blue or Grey SmokeIf the smoke from the exhaust pipe is either grey or bluish-tinged, it generally means that your engine is burning oil inside the combustion chamber. Burning oil could be due to a number of causes, from leaky valve seals to bad piston rings.
What color is the exhaust when burning oil?
Blue/gray exhaust smoke means there's likely an oil leak and your engine is burning oil. Time to have a qualified technician check things out. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or worn cylinder walls.What does grey smoke mean?

Billowing black smoke is generally a sign that the fuel-air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren't letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter.What does blue exhaust smoke indicate?
Blue smoke can often look like grey smoke at first. But if you notice a distinctive bluish tint, it may signal that the engine is burning lots of oil. This could be due to worn engine components like piston rings, valve seals, or PCV (Positive Crankcase Ventilation) valves.Why does my car smoke when I accelerate hard?
Smoke often leaves car engines as a result of overheating. This can be caused by faulty wire casings, heated residues on the engine block and overheated liquids including oil, transmission fluid and brake fluid. There may also be a fault in your coolant system, or your engine may not have enough lubricant.Is white smoke from exhaust normal in cold weather?
White smoke from the tailpipe is normal during cold starts, especially in cold weather. However, we'll dig into that later.

Car Running Rich Symptoms
- Check Engine Light.
- Pungent Smell.
- Excess Fuel Consumption.
- Poor Engine Performance.
- High Carbon Monoxide Emissions.
- Foul Spark Plugs.
- Black Smoke From the Exhaust Pipe.
What are the symptoms of a rich fuel mixture?
A fuel mixture that is rich could be the cause of rough idling. This means the vehicle will actually vibrate and feel a bit rough as the engine is running. While the car is not moving (idle), you may notice that the RPMs on the tachometer behave erratically, slightly jumping around.Can Rich condition cause white smoke?
A diesel engine requires precision timing and fuel pressure of the injector pump. When the timing is not what it's supposed to be, your engine will essentially be running rich which will cause fuel to not completely burn and instead exit out of the exhaust as white or gray smoke.
