What color is synthetic oil smoke?
Smoke coming from the exhaust after a vehicle has warmed up is attributed to oil burning during the combustion process. A switch to a more stable, synthetic oil would be the way to stop a blue-tinged smoke from emerging from the exhaust.
What color is smoke when you burn oil?
Blue
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.
Can synthetic oil cause white smoke?
White smoke most likely would indicate that water or coolant is getting into the combustion chamber or exhaust port. Another cause of the smoke could be that the oil originally in the engine was a mineral oil but was replaced with a synthetic oil, which has a greater cleaning effect on varnish and soot deposits.
Does synthetic oil smoke like regular oil?
Synthetic oil generally smokes much less than regular. I suspect you see smoke now because you are using a much lower viscosity, the heavy weight oil probably didn’t leak by as much so it didn’t make as much smoke. I don’t see any reason the old oil would get “burnt off” if it wasn’t burning before.

Will synthetic oil burn less?
MYTH: Synthetic oils are too thin and can create blow-by and oil burn-off in older cars. Synthetic motor oils do not affect seals and will not be the cause of blow-by or oil burn-off in an older engine. Just like conventional motor oil, synthetic oils have a specific viscosity grade.
Can overfilling oil cause blue smoke?
The most common overfill engine oil symptom is white smoke with a blue or grey tint. You may find your car emitting too much white smoke which is the result of burning an excessive oil that creeps into the combustion chamber. It is one of the most visible overfilled engine oil vehicles.
Why is my exhaust smoking with synthetic oil?
