When to Add Oil
If the oil is at or below the ADD mark, then you'll need
to add some oil. But you must use the right kind. This
part explains what kind
of oil to use. For crankcase
capacity, see "Capacities and Specifications"
in the Index
NOTICE:
Don't add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
The engine oil fill cap
for the 4.3L, S.OL and the
S.7L engine is located on
the driver's side engine
valve cover.
The engine oil
fill cap for the 7.4L engine is located at
the front
of the engine.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
hack in when you're through.
