    3. 15%-20%
    4. Driving in snow has no effect on fuel consumption
  5. What pressure should the tires be inflated to?
    1. A standard inflation set by the load that is being carried
    2. The inflation recommended by the tire manufacturers
    3. 10 psi below the maximum recommended tire pressure
    4. 10 psi above the minimum recommended tire pressure
  6. Before moving off on a warm day (15°C), how long should you should idle your engine from a cold start?
    1. Up to 1 minute
    2. 3 – 5 minutes
    3. 2 – 3 minutes
    4. 7 – 10 minutes
  7. Which of the following is the most effective way to save fuel?
    1. Avoid idling
    2. Reduce speed from 105 km/h to 90 km/h
    3. Maintain high engine r.p.m.
    4. Use progressive shifting
  8. What does the term “Progressive Shifting” refer to?
    1. Up-shifting while traveling uphill
    2. Downshifting when travelling downhill
    3. Shifting at the governed maximum engine r.p.m.
    4. Shifting before the engine reaches maximum r.p.m.
  9. An idling tractor-trailer engine burns up to:
    1. One litre of fuel per hour at 900 r.p.m.
    2. Two litres of fuel per hour at 900 r.p.m.
    3. Three litres of fuel per hour at 900 r.p.m.
    4. Four litres of fuel per hour at 900 r.p.m.
  10. With new diesel engines, you should downshift and up-shift at approximately:
    1. 1200 and 1600 r.p.m.
    2. 1500 and 1800 r.p.m.
    3. 1600 and 1900 r.p.m.
    4. 1700 and 2000 r.p.m.

Answers

  1. C - Plan your route carefully: flat routes are more fuel efficient than mountainous routes; highway driving is more fuel efficient than “inner city” driving.
  2. D - Optimize tractor aerodynamics: reducing aerodynamic drag by 10% can increase fuel efficiency by 5%.
  3. D - Choosing to drive a flat, multi-lane highway improves your fuel efficiency by: 4 to 11% compared to a flat two-lane highway; as much as 18% compared to a mountainous highway; and 25 to 35% over taking a suburban route.
  4. C - Weather conditions affect fuel efficiency. Driving on snow-covered roads can increase fuel consumption by 15 to 20%.
  5. B - Ensure your tires are inflated according to the manufacturer’s recommendations — 1% of fuel is wasted for each 10 pounds per square inch of under-inflation.
  6. B - Let your vehicle warm up for three to five minutes—if the temperature is below 0 degrees Celsius, allow it to warm up for seven to 10 minutes. Do not rev it; let it warm up gradually.
  7. B - Reduce your average speed — driving fast eats up fuel no matter what you drive.
  8. D - Practise progressive gear-shifting at approximately 1600 r.p.m. Shifting before you reach the maximum governed r.p.m. reduces equipment wear, decreases noise levels and saves fuel.
  9. D - Idling a tractor-trailer engine burns up to four litres of fuel per hour at 900 r.pm.
  10. A - New engine designs offer great benefits, delivering more horsepower and torque in lower r.p.m. ranges. You can downshift at about 1200 r.p.m. and up-shift at about 1600 r.p.m. — rather than 2000 r.p.m. You shift less, save money and generate fewer emissions.
