The Importance of Level Ground for an Accurate Oil Check
On an Incline Low Not recommended. It is critical that the vehicle is positioned on level ground, as checking on the side of a road or in a driveway with even a slight slope will render the measurement inaccurate regardless of how long you wait.

Many newer vehicles are equipped with electronic oil life monitors or digital dipsticks that calculate remaining oil life based on driving conditions rather than just a physical stick.
Checking Oil on Level Ground for Accurate Readings
Why Timing and Conditions Matter The state of your oil changes the moment you turn the ignition off.
