Fuel EconomyImproving Fuel EconomyFuel economy depends on several conditions, including driving conditions, your
driving habits, the condition of your vehicle, and loading. Depending on these and
other conditions, you may or 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
multi-information display.
•Use the recommended viscosity engine oil, displaying the API Certification Seal.
• Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.■

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 Acura 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 Acura Motor Oil
• Premium-grade 0W-20 detergent oil with an API Certification Seal on the
container.
