Use of Wrong Oil

Your car’s engine may smoke excessively if you use the incorrect type of oil and viscosity. It happens as a result of the engine oil not being burnt properly and entering the exhaust. Your exhaust starts to spew out white smoke as a result.

Fortunately, you could simply and cheaply solve this issue by purchasing the proper oil type at any vehicle retailer.

Pro Tip: If you want to prevent this from happening, always go to your owner’s manual guide before changing the oil in your automobile and follow its instructions exactly. When individuals service their cars, they frequently use the incorrect type of oil, which causes white smoke to come from your exhaust pipe.

Too much Oil in the Sump

The bluish-white fume emerging from your exhaust after an oil change may indicate excess oil in your car’s engine oil sump. After a change of oil, when you add new oil to your automobile, it frequently overflows into the engine’s sump because of air pressure which keeps the oil from draining out of your engine.

If this occurs, stop driving the car and have some surplus oil from the sump drained by a professional.

Leakage from Valve Stem Seal

Oil can leak through the valve stem’s seal into the combustion area, where it could burn and emit white smoke. This problem can be fixed by replacing the stem seals of the hollow rubber valve in the engine, which are on either side of the valves in your car.

Blown Head Gasket

Your car may have a leak from a burst head gasket, which causes it to burn spilled oil in the cylinder instead of gasoline if coolant or water do not enter the combustion chamber. White smoke will therefore come out of your car’s exhaust.

Immediately you notice this problem; you should have your car inspected by an expert because, if left unattended for an extended period, it might lead to significant issues with the engine’s cooling system.
