Driving Fuel Economy and CO 2
EmissionsImproving Fuel Economy and Reducing CO 2
Emissions Achieving fuel economy and reducing CO 2
emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
driver information interface.
• Use the recommended viscosity engine oil. 2 Recommended Engine Oil P. 484
• Maintain the specified tire pressure.
• Do not load the vehicl e with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle's underside
adds weight and increases wind resistance.■ Maintenance and Fuel Economy 1 Improving Fuel Economy and Reducing CO 2
Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more

484 uu Maintenance Under the Hood u Recommended Engine Oil
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.
This seal indicates the oil is energy conserving
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.
■ Synthetic oil
You may also use synthetic motor oil if it is labeled with the API Certification Seal
and is the specified viscosity grade. • Genuine Honda Motor Oil
• Premium-grade 0W-20 detergent oil wi th an API Certification Seal on
the container. 1 Recommended Engine Oil
Engine Oil Additives
Your vehicle does not require oil additives. In fact,
they may adversely affect the engine performance
and durability.
