highly recommended that you use
Honda Motor Oil in your vehicle for
optimum engine protection. Make
sure the API Certification Seal says

less fuel.

Adding Engine Oil
Synthetic Oil
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 multi-
information display.
Engine Oil Additives
Your vehicle does not require any oil
additives. Additives may adversely
affect the engine or transmission
performance and durability.
