To add oil, unscrew and remove the
engine oil fill cap on top of the valve
cover. Pour in the oil, and install the
engine oil fill cap. Tighten it securely.
Wait a few minutes and recheck the
oil level. Do not fill above the upper
mark; you could damage the engine. Pour the oil slowly and carefully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.
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.
