HONDA 2008 Odyssey - Manual (Page 425)

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.’’
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. You must
follow the oil and filter change
intervals shown on the odometer/
trip meter display or on the multi-
information display.
Your vehicle’s engine does not
require any oil additives. Additives
may adversely affect engine or
transmission performance and
durability.
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.
