2003 Acura TL oil

You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal,
and it is the proper weight as shown
on the chart. When using synthetic
oil, you must f ollow the oil and f ilter
change intervals given in the
maintenance schedule.
The SAE number tells you the oil’s
viscosity or weight. Select the oil f or
your vehicle according to this chart.
5W-20 oil is f ormulated f or year-
round protection of your Acura, to
improve cold weather starting, and
to help your engine use less f uel.
If 5W-20 oil is not available, a 5W-30
oil may be used. However, it should
be replaced with 5W-20 at the next
oil change.

Always change the oil and f ilter
accordingtothetimeanddistance
(miles/kilometers) recommenda-
tions in the maintenance schedule.
The oil and f ilter collect contami-
nants that can damage your engine if
they are not removed regularly.
Changing the oil and f ilter requires
special tools and access f rom
underneath the car. The car should
be raised on a service station-type
hydraulic lif t f or this service. Unless
you have the knowledge and proper
equipment, you should have this
maintenance done by a skilled
mechanic.Run the engine until it reaches
normal operating temperature,
then shut it off.
Your Acura does not need any oil
additives. Purchasing additives f or
the engine or transmission will not
increase your car’s perf ormance or
longevity. It only increases the cost
of operating your car. 1.

Tighten the spark plugs caref ully. A
spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage to
the threads in the cylinder head.

Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently.
Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them. 318

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.
