Why does the Verna burn oil without emitting smoke?

[Myrtle]

It may be that the engine oil is entering the cylinder and being burned. Oil being burned: There are two scenarios for an engine burning oil: one is the oil entering the cylinder and being burned, while the other is the oil being consumed elsewhere. Burning oil in the combustion chamber usually produces blue smoke, but if the oil is leaking elsewhere, it won't produce blue smoke. Therefore, the absence of blue smoke indicates that the oil is being consumed by other components. Minor oil burning: If the car burns oil without emitting blue smoke, it only means the oil burning is minor and not visible to the naked eye. It's best to also check for oil leaks, as leaks can also cause a reduction in oil levels.
