Make sure the API Certification Seal
says ‘‘For Gasoline Engines’’.
Oil is 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.
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and carefully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.
Install the engine oil fill cap, and
tighten it securely. Wait a few
minutes, and recheck the oil level.
Do not fill above the upper mark; you
could damage the engine.
The oil’s viscosity or weight is
provided on the container’s label.
5W-20 oil is formulated for year-
round protection of your vehicle, to
improve cold weather starting and
fuel economy.
