HONDA 2011 Civic Coupe - Manual (Page 306)

Oil is a major contributor to your
engine’s performance and longevity.
Always use a premium-grade
detergent oil displaying the API
Certification 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 for
optimum engine protection.
Reinstall the engine oil fill cap, and
tighten it securely. Wait a few
minutes, and recheck the oil level on
the engine oil dipstick. Do not fill
above the upper mark; you could
damage the engine. Unscrew and remove the engine oil
fill cap on the valve cover. Pour the
oil slowly and carefully so you do not
spill any. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.
