TUESDAY TIP!
A little quiz - Which of these driving habits waste the most fuel?
You might think the answer is A — A/C: Uses additional fuel, but the effect varies with conditions. OR even
B — Open windows: Because they can increase aerodynamic drag at highway speeds.
HOWEVER -
The best answer is F — keeping a roof rack on the car. 🚗💨
A roof rack creates constant aerodynamic drag, especially at highway speeds, so the engine has to work harder. Tests have found that even an empty roof rack can reduce highway fuel economy by around 10–12% on some vehicles.
D&E also waste fuel:
D — Warming the car up: Idling unnecessarily burns fuel. The car generally warms up faster while driving gently.
E — Tailgating: Don't do it! It may reduce aerodynamic drag slightly, but the safety risk is absolutely not worth it.
