Maintenance Recommended Engine Oil Oil is a major contributor to your engine's
performance and longevity. If you drive the
vehicle with insufficient or deteriorated oil,
the engine may fail or be damaged.

and that it meets the American Petroleum
Institute’s latest requirements.
Use a Genuine Honda Motor Oil or another
commercial engine oil of suitable viscosity for
the ambient temperature as shown.
