2004 Acura RSX oil viscosity

Make sure the API Certif ication Seal
says ‘‘For Gasoline Engines’’.
The oil’s viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your Acura, to
improve cold weather starting and
f uel economy.
To add oil, unscrew and remove the
engine oil f ill cap on top of the valve
cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.
Install the engine oil f ill cap and
tighten it securely. Wait a f ew
minutes and recheck the oil level. Do
not f ill above the upper mark on the
dipstick; you could damage the
engine. Oil is major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements. It is
highly recommended that you use
Honda motor oil in your vehicle.

An oil with a viscosity of 5W-30 is
pref erred f or improved f uel economy
and year-round protection in your
Acura. You may use a 10W-30 oil if
the temperature in your area never
goes below 20°F ( 7°C). Your Acura does not require any oil
additives. Additives may adversely
af f ect your engine’s or transmission’s
perf ormance and durability.Always change the oil and f ilter
according to the recommendations in
the maintenance schedule. The oil
and f ilter collect contaminants 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 vehicle. The vehicle
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.
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. You must
f ollow the oil and f ilter change
intervals given in the maintenance
schedule.

Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can affect the shift quality. Have
the transmission f lushed and ref illed
with Honda ATF-Z1 as soon as it is
convenient.
To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1, then drive the
vehicle f or a short distance. Do this
three times. Then drain and ref ill the
transmission a f inal time.
Insert the dipstick all the way back
in the transmission.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule. Check the f luid level with the
transmission at normal operating
temperature and the vehicle sitting
on level ground. Remove the
transmission f iller bolt, and caref ully
f eel inside the bolt hole with your
f inger. The f luid level should be up
to the edge of the bolt hole. If it is
not, add Honda Manual
Transmission Fluid (MTF) until it
starts to run out of the hole. Reinstall
the f iller bolt, and tighten it securely.If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives, and continued use can
cause stiffer shifting. Replace as
soon as it is convenient.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
