Chevrolet Kodiak 2008 Owner's Manual page 237

This section explains what kind of oil to use. For engine
oil crankcase capacity, see Capacities and
Specifications on page 5-109.
If the oil is below the ADD
mark on the dipstick, add
at least one quart/liter
of the recommended oil.
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.
Add oil at the engine oil fill
cap in the engine
compartment. Install and
fully tighten the fill cap
when you are through.
