HONDA 2003 Civic Coupe - Owner's Manual - Manual (Page 207)

The SAE number tells you the oil’s
viscosity or weight. Select the oil for
your vehicle according to this chart.
You may use a synthetic motor oil if
it meets the same requirements
given for a 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.
Your Honda does not require any oil
additives. Additives may adversely
affect your engine’s or transmission’s
performance and durability.
5W-20 oil is formulated for year-
round protection of your Honda, to
improve cold weather starting, and
to help your engine use less fuel.
