    Oil check issue

    Checked the oil in the car this morning after op temp reached. Noticed the rooms dropped when removing the dip stick then returning to normal when putting it back in. Anyone know what that means?

    Are you saying that you are checking the oil while the engine is running and the RPMS drop?

    If so that would be normal, because you are breaking the PCV systems vacuum by removing the stick.

    Check the oil with the engine OFF, after it has reached operating temperature.

    Makes sense, I swear we were told in class to do it while on.

    Nah, just warm the car up 1st because motor oil is like maple syrup in that it gets thicker when it's cold.

    You're lucky you didn't get a hot oil shower.

    Maybe you were thinking of automatic transmission fluid
