HONDA 2010 Ridgeline - Manual (Page 330)

Oil is a major contributor to your
engine’s performance and longevity.
Always use a premium-grade 5W-20
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.
Honda Motor Oil is the preferred
5W-20 lubricant for your vehicle. It is
highly recommended that you use
Honda Motor Oil in your vehicle for
optimum engine protection. Make
sure the API Certification Seal says
‘‘For Gasoline Engines.’’
The oil 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.
Unscrew and remove the engine oil
fill cap on the valve cover. Pour in
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. 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.
