Cadillac DTS Owner Manual - 2011

Obtaining an accurate oil level reading is essential:

1. If the engine has been running recently, turn off

the engine and allow several minutes for the oil to
drain back into the oil pan. Checking your oil level
too soon after engine shut off will not provide an
accurate oil level reading.

2. Pull out the dipstick and clean it with a paper towel

or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

When to Add Engine Oil

If the oil is below the cross-hatched area at the tip of
the dipstick, add one liter/quart of the recommended oil
and then recheck the level. See “Selecting the Right
Engine Oil” for an explanation of what kind of oil to use.
For engine oil crankcase capacity, see Capacities and
Specifications on page 6‑112
.

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 6‑14 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.
