GMC Acadia/Acadia Denali Owner Manual - 2011
Vehicle Care 10-9
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 your
driving of the vehicle and seek a
service professional to remove
the excess amount of oil.
See Engine Compartment Overview
on page 106 for 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.
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade:
Specification
Use and ask for engine oils with
the dexos certification mark.
Oils meeting the requirements
of your vehicle should have the
dexos certification mark on the
container. This certification mark
indicates that the oil has been
approved to the dexos
specification.
Your vehicle was filled at the factory
with dexos approved engine oil.
Notice: Use only engine oil
that is approved to the dexos
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine oils
approved to the dexos
specification will show the
dexos symbol on the container.
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered
by the vehicle warranty. If you
are unsure whether your oil
is approved to the dexos
specification, ask your service
provider.
