the dipstick for the 6.6L V8 (LLY) engine, you will need
to add at least two quarts/liters of oil. If the oil is
below the lower hole at the tip of the dipstick for the
7.8L L6 (LG4) engine, 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, seeCapacities and
Speci cations on page 5-99.
Notice:Do not add too much oil. If your engine
has so much oil that the oil level gets above
the cross-hatched area for the 6.6L V8 (LLY) engine
or above the upper hole that shows the proper
operating range for the 7.8L L6 (LG4) engine, your
engine could be damaged.

fill cap in the engine
compartment. Install and
fully tighten the fill cap
when you are through.

the proper operating range. Push the dipstick all the
way back in when you are through. 6.6L V8 (LLY) Engine
