Acura 2003 NSX - Owner's Manual - Manual (Page 185)

Your Acura does not need any oil
additives. Purchasing additives for
the engine or transmission will not
increase your car’s performance or
longevity. It only increases the cost
of operating your car.
You may use a synthetic motor oil if
it meets the same requirements
given for conventional motor oil: it
displays the API Certification Seal,
and it is the proper weight as shown
on the chart. When using synthetic
oil, you must follow the oil and filter
change intervals given in the
maintenance schedule.
The numbers on the container’s label
tell you the oil’s viscosity or weight.
Select the oil for your car according
to this chart.
An oil with a viscosity of 10W-30 is
preferred for optimum fuel economy
and year-round protection in your
Acura. You may use a 5W-30 oil if
the temperature in your area goes
below 32°F (0°C).
Make sure the API Certification Seal
says ‘‘For Gasoline Engines.’’
