Whining or Whirring Noise
A whining or whirring noise is one of the most common signs of low oil levels. This noise is usually heard when the engine is under load, such as when you are accelerating or climbing a hill.

If you notice a knocking or clunking noise, it is essential to check your oil levels immediately and add oil if necessary.
Grinding or Screeching Noise
A grinding or screeching noise is a more severe sign of low oil levels. This noise is usually heard when the engine is under load, such as when you are accelerating or climbing a hill.
