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.
This seal indicates the oil is energy conserving
and that it meets the American Petroleum
Institute’s latest requirements.
Use Honda Genuine Motor Oil or another
commercial engine oil of suitable viscosity for
the ambient temperature as shown.
■Synthetic oil
You may also use synthetic motor oil if it is labeled with the API Certification Seal
and is the specified viscosity grade.

container.1Recommended Engine Oil
Engine Oil Additives
Your vehicle does not require oil additives. In fact,
they may adversely affect the engine performance
and durability.
