6-23 When to Add Engine Oil
If the oil is at or below the cross-hatched area, then
you'll need to add at least one quart of oil. But you must
use the right kind. This part explains what kind of oil to
use. For engine oil crankcase capacity, see ªCapacities
and Specificationsº in the Index.
NOTICE:
Don't add too much oil. If your engine has
so much oil that the oil level gets above the
cross
-hatched area upper mark that shows
the proper operating range, your engine could
be damaged.
The engine oil fill cap is
located near the engine oil
dipstick in the engine
compartment, on the
driver's side of the vehicle.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you're through.

6-28 When to Add Engine Oil
If the oil is at or below the ADD line, then you'll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use.
For engine oil crankcase capacity, see ªCapacities and
Specificationsº in the Index.
NOTICE:
Don't add too much oil. If your engine has so
much oil that the oil level gets above the proper
operating range, your engine could be damaged.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you're through.
What Kind of Engine Oil to Use
Look for these two things:

CH
-4
Oils designated as API CH
-4 are best for your
vehicle. The CH
-4 designation may appear either
alone or in combination with other API designations,
such as API CH
-4/SJ or CH-4/CG-4/SJ.
These letters show American Petroleum Institute
(API) levels of quality.
NOTICE:
If you use oil that doesn't have this designation,
CH
-4, you can cause engine damage which is not
covered by your warranty.

** Check fill level on the oil indicator after initial fill to
make sure it is actually full. Oil level may vary
depending on vehicle option content.

6-89 Transmission Capacity
For manual transmissions, the correct oil level is to the
bottom of the fluid fill plug opening. The oil capacity
will vary, due to the angle of the transmission, with the
vehicle. For automatic transmissions, see the Allison
Automatic Transmission Operator's Manual for oil
check and maintenance information.
