Fuel Economy Fuel Economy Factors The following factors can lower your vehicle's fuel economy: ● For example: ● ● 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 Use the recommended viscosity motor oil, displaying the API Certification Seal (see page 517). Maintain proper tire inflation － An underinflated 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. ● ● ● Observe the speed limit － Aerodynamic drag has a big effect on fuel economy 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. Avoid excessive idling － Idling results in 0 miles per gallon (0 kms per liter). Before Driving ● ● ● ● ● ● 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 multiinformation display (see Owner's Maintenance Checks on page 513). Drive Efficiently ● Drive moderately － Rapid acceleration, abrupt cornering, and hard braking increase fuel consumption. CONTINUED 429 2013 MDX
