Standard Procedure - Engine Oil Level Check
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, and 2002 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
The best time to check engine oil level is after it has sat overnight, or if the engine has been running, allow the engine to be shut off for at least 5 minutes before checking oil level.
Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level reading (Fig 1). Add only when the level is at or below the ADD mark.
