2. Oil leaks

As usual, oil leaks occur from bad valve sealsor by cracks in the engine due to wear. These leaks in the supply lines cause leaks in the engine oil and leak when the fluid is refilled in the engine. The F’sLeaks possibly cause the dipstick to not indicate any oil level, so it comes out dry.

3. Increased oil consumption by the engine

If you notice that there is no oil on the dipstick with a cold engine, and after a normal maintenance service, it is due to excessive oil consumption.. It’s a indicator that the engine is presenting serious faults, with defective internal parts. For example: a damaged cylinder head gasket, can lead to more than normal oil consumption. The head gasket forms a seal between the engine block and this part. Broken or defective seals consume more oil, so the dipstick does not detect oil in the sump.

4. You don’t know how to check the dipstick

  • If the car’s engine is hot, you should wait at least an hour for the engine to cool down. This is because the liquid adheres to the rod more easily when it is cold. Waiting for the engine to cool down ensures that oil trapped anywhere in the engine can be returned to the crankcase.
  • After all these steps you will be able to discover the reasons why the rod is dry. Make sure there are no oil leaks.
