You discover that your fuel consumption is higher than it should be. What is the most likely cause of this:
Steering too sharply
Driving over 120kph
Using high gears
Explanation: Accelerating at low rpm, or in too high a gear, means that the engine is working harder, placing unnecessary strain on the motor. Change down and allow the revs to rise before changing up. This is particularly important when carrying heavy loads or when climbing hills.
