    Hi,

    I checked my car oil when engine was warm and the reading was perfect... so next day I checked again when the engine was cold and surprisingly the reading was low?? Why is this? Am I checking the oil the wrong way is their some kind of procedure to check the oil?

    Cheers!

    Cold reading is the one to go onto, and the oil expands as it warms as you have noticed already
