Canada (TC) Fuel Economy Estimates
EPA and TC fuel economy figures are obtained

fuel economy estimate is not a guarantee that
you will achieve the fuel economy shown.

Lack of regular, scheduled maintenance
Excessive speed
Rapid acceleration
Driving with your foot on the brake
Sudden stops
Extended engine idling
Using speed control in hilly terrain
