Ford Fusion: Fuel and Refueling / Fuel Consumption

Advertised Capacity

The advertised capacity is the maximum amount of fuel that you can add to the fuel tank after running out of fuel. Included in the advertised capacity is an empty reserve. The empty reserve is an unspecified amount of fuel that remains in the fuel tank when the fuel gauge indicates empty.

Note: The amount of fuel in the empty reserve varies and should not be relied upon to increase driving range.

Calculating Fuel Economy

Your vehicle calculates fuel economy figures through the trip computer average fuel function.

The first 1,000 mi (1,600 km) of driving is the break-in period of the engine. A more accurate measurement is obtained after 2,000–3,000 mi (3,200–4,800 km).

Keep a record for at least one month and record the type of driving, for example city or highway. This provides an accurate estimate of your vehicle’s fuel economy under current driving conditions. Keeping records during summer and winter shows how temperature impacts fuel economy.

Conditions Affecting Fuel Efficiency

• Carrying unnecessary weight in your vehicle may reduce fuel economy.
• Avoid adding accessories that increase aerodynamic drag to your vehicle such as bug deflectors, car top carriers and ski or bike racks.
• Remove empty roof racks and keep windows shut at high speeds to reduce wind resistance and fuel use.
• Check and adjust tire pressure regularly. Underinflated tires increases fuel consumption.
• Sudden acceleration and braking degrade fuel efficiency. Drive smoothly looking as far ahead as possible and avoid short trips when possible.
• Fuel efficiency degrades with lower temperatures.
• Comfort features use additional energy and consume more fuel. Use AC and other comfort features only when necessary.
• Using fuel blended with alcohol may increase fuel consumption.
