When to Add Engine Oil If the oil is below the MIN (minimum) mark, you will need to add at least one quart/liter of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 385. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, the engine could be damaged. 2.2L L4 Engine and 2.4L L4 Engine 2.0L L4 Supercharged Engine See Engine Compartment Overview on page 284 for the location of the engine oil fill cap. Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you are through. 288
