When to Add Engine Oil
3.9L V6 Engine
4.6L V8 Engine
If the oil is below the cross-hatched area at the tip of
the dipstick, add 1 L (1 qt) of the recommended oil
and then recheck the level. See “Selecting the Right
Engine Oil” in this section for an explanation of what
kind of oil to use. For engine oil crankcase capacity, see
Capacities and Specifications on page 6‑116. Notice:
Do not add too much oil. Oil levels above or
below the acceptable operating range shown on the
dipstick are harmful to the engine. If you find that
you have an oil level above the operating range, i.e.,
the engine has so much oil that the oil level gets
above the cross-hatched area that shows the proper
operating range, the engine could be damaged. You
should drain out the excess oil or limit driving of the
vehicle and seek a service professional to remove
the excess amount of oil.
See Engine Compartment
Overviewon page 6‑14for the location of the
engine oil fill cap.
Add enough oil to put the level somewhere in the proper
operating range. Push the dipstick all the way back in
when through.
