Driving more efficiently
Practicing the following fuel efficient driving techniques can improve fuel economy more than 10%:
•Observing the Speed Limit
In highway driving, over 50% of the energy required to move your car down the road goes to overcoming aerodynamic drag (pushing air out of the way). As you drive faster, aerodynamic drag and rolling resistance increase. As a result, at speeds above 80 km/ h, fuel economy decreases rapidly.
By driving 100 km/h instead of 120 km/h, you’ll save gas. Of course it will take you longer to get to your destination, but for each extra hour you spend driving you’ll save $5. Owners of larger trucks and sport utility vehicles may save as much as $10 for each extra hour spent driving.
Staying within the speed limit is not only a matter of safety and obeying the law, it can also save you money!
Over-drive gears improve the fuel economy of your car during highway driving. When you use over-drive gearing your car’s engine speed decreases. This reduces both fuel consumption and engine wear.
•Using Cruise Control
Using cruise control on highway trips can help you maintain a constant speed and, in most cases, will reduce your fuel consumption.
