Fuel Economy
Fuel economy is an estimate of the efficiency of
your vehicle and can be calculated as Miles Per
Gallon (MPG) or liters Per 100 Kilometers (L/
100K).
Do not calculate fuel economy during your vehicle's
break-in period. This would not be an accurate
estimate of how much fuel your vehicle will
normally use.
To calculate fuel economy:
I . Fill the tank completely and record the initial
odometer reading.
2. Every time you buy fuel record the amount (in
gallons or liters) purchased.
3. After at least three to five tankfuls, fill the fuel
tank and record the final odometer reading.
4. Use these equations to calculate your fuel
economy.
English: MPG = (total miles)/(gallons used).
Metric: L/100K = (liters used) x 100/(total
kilometers)
Comparisons With EPA Fuel Economy
Estimates
EPA fuel economy figures are obtained from
laboratory tests under simulated road conditions and
may not reflect the actual conditions you experience
or your style of driving. The EPA fuel economy
estimate is not a guarantee that you will achieve the
fuel economy shown.
The following decrease fuel economy:
Lack of regular, scheduled maintenance
Rapid acceleration and excessive speed
Driving with your foot on the brake
Sudden stops
Extended engine idling
