Debunking 10 Widespread Fuel Economy Myths

Despite that we live in the era of information, ironically, misconceptions and myths are still around. So, take for example, a mundane topic as ‘vehicle fuel economy’ – while you have full access to a lot of useful and most importantly legitimate information, when you find yourself surfing online you’re also stumbling upon countless number of suggestions, based on opinions rather than scientifically proven facts.

Also, as cars are considered the second most expensive purchase, depending on people’s opinions on ‘fuel economy’, car dealers have a lot to lose profit-wise. Should I use fuel additives and will they decrease economy? Is it best to buy a small car to save more gas? Should I opt for premium fuel rather than conventional one? Should I let my car warm up first? Puzzling questions like these require reliable answers, which is why we’ve complied a list based on the official U.S. EPA data to shed some light on the topic and provide you with some useful information to help you make wiser financial decisions in regards to fuel economy.

1. Myth - Warming up your vehicle is best for gas mileage

With the exception of defrosting your vehicle during the cold winter days to let it warm up inside, there is no other good reason to do so. Modern vehicles are designed to drive immediately after the start, as surprise, surprise – when you’re car is sitting it gets 0 mpg. To reach optimal operating temperature for best fuel economy, manufacturers advise to take off gently and let your engine warm while the car is already set in motion.

2. Myth - Fuel economy decreases as the vehicle ages.

Will your car become less efficient with time? To ensure that your original spec remain the same, it’s essential that you take good care of your car, as EPA states ‘vehicles that are 10 or even 15 years old will experience little decrease in fuel economy if properly maintained’. Then buying a new car should not be based on the assumption that fuel economy decrease with time, but on the fact that you’re now ready to lay your hands on a vehicle that greener and even more efficient.


3. Myth - The federal government tests fuel economy for all vehicles

Vehicles that exceed 8,500 pounds and are used to do duty for passengers such as Ford F250/350, Chevrolet/GMC 2500/3500, and Dodge 2500/3500 are not subject to testing. However, the government is doing tests on most passenger cars and light-duty trucks.
