As gas prices continue to climb, many drivers are looking for ways to save at the pump. However, some common fuel-saving practices may be doing more harm than good. One such myth is the habit of topping off your tank, which experts say can actually waste fuel and damage your vehicle.
The Top-Off Myth
Many drivers believe that topping off their gas tank after the nozzle clicks off will give them extra range. In reality, modern fuel pumps are designed to stop automatically when the tank is full. Continuing to add fuel can cause it to seep into the vapor recovery system, leading to increased emissions and potential damage to your car's evaporative emissions system.
Other Common Fuel Efficiency Myths
- Premium fuel improves mileage: Unless your vehicle requires premium, using it will not boost fuel economy. Stick to the grade recommended in your owner's manual.
- Idling uses less fuel than restarting: Idling for more than 10 seconds uses more fuel than turning off and restarting your engine. Modern engines are designed for efficient starts.
- Air conditioning always hurts mileage: At highway speeds, using A/C can be more efficient than opening windows, which creates drag.
What Actually Saves Fuel
To improve fuel efficiency, focus on proper tire inflation, reducing excess weight, and maintaining a steady speed. Aggressive driving, such as rapid acceleration and hard braking, can lower gas mileage by up to 40%.
With gas prices reaching record highs in Edmonton and across Canada, understanding these myths can help drivers avoid wasting money and keep their vehicles running efficiently.
