Main Menu Table Of Contents Fuel Economy Fuel Economy Factors The following factors can lower your vehicle's fuel economy: Aggressive driving (hard acceleration and braking) Excessive idling, accelerating and braking in stop-and-go traffic Cold engine operation (engines are more efficient when warmed up) Driving with a heavy load or the air conditioner running Improperly inflated tires Improving Fuel Economy Vehicle Maintenance A properly maintained vehicle maximizes fuel economy. Poor maintenance can significantly reduce fuel economy. Always maintain your vehicle according to the maintenance messages displayed on the information display (see Owner's Maintenance Checks on page 245 ). For example: Use the recommended viscosity motor oil, displaying the API Certification Seal (see page 248). Maintain proper tire inflation An under-inflated tire increases ''rolling resistance,'' which reduces fuel economy. Avoid carrying excess weight in your vehicle It puts a heavier load on the engine, increasing fuel consumption. Keep your vehicle clean In particular, a build-up of snow or mud on your vehicle's underside adds weight and rolling resistance. Frequent cleaning helps your fuel economy. Drive Efficiently Drive moderately Rapid acceleration, abrupt cornering, and hard braking increase fuel consumption. Observe the speed limit Aerodynamic drag has a big effect on fuel mileage at speeds above 45 mph (75 km/h). Reduce your speed and you reduce the drag. Trailers, car top carriers, roof racks and bike racks are also big contributors to increased drag. Always drive in the highest gear possible If your vehicle has a manual transmission, you can boost your fuel economy by up shifting as early as possible. Idling Avoid excessive idling results in 0 miles per gallon. Minimize the use of the air conditioning system The A/C puts an extra load on the engine which makes it use more fuel. Use the fresh-air ventilation when possible. Plan and combine trips Combine several short trips into one. A warmed-up engine is more fuel efficient than a cold one. 186 2008 Ridgeline
