7: Reduce drag to improve fuel efficiency.
As you’ve likely heard before, there are statistics to back up my point. While aerodynamic drag in city driving isn’t a major problem, it really kills your gas mileage over 90 mph. You can increase your drag by 36 per cent by speeding up to 105km/h! You could lose hundreds of dollars a year just by getting to your destination a few minutes early if you drive the highways a lot. Use your cruise control and drive closer to 90 mph. You’ll be glad you did.
