With fuel prices in a constant state of flux, drivers are always on the lookout for tips and tricks to improve their car’s gas mileage. Unfortunately, there are plenty of myths out there that won’t improve your fuel economy at all. Chances are you’ve heard at least a few.

Let’s go over them below.

6 Big Gas Mileage Myths

You should keep your windows rolled up

It’s well-known that using the air conditioning will decrease your fuel efficiency. But what about opening the windows? Some drivers claim that this method will create drag and decrease the performance of a car’s aerodynamics. However, there is no such evidence that driving with the windows up improves your car’s performance.

Idling uses less gas than starting

If this myth was true, then the hybrid and newer vehicles with stop and start systems would be consuming even more gas than usual. By letting your car idle when you quickly run into the store, you’re actually wasting gas.

Dirty air filters drag you down

Modern fuel-injected engines aren’t affected by a dirty air filter in terms of fuel efficiency. In fact, a 2009 study done by the U.S. Energy Department found that replacing the air filter can help your engine’s performance — but not fuel economy.

You should coast on the downhill

Even if you take your foot off the accelerator while driving downhill, your modern fuel-injected car continues to burn fuel.

A little extra weight is okay

If you’re driving around with your set of golf clubs hoping to sneak in a quick nine holes, that extra weight could be diminishing your gas mileage. The U.S. Energy Department has determined that an extra 100 lbs. of weight can decrease your fuel economy by 1%.

You should over-inflate your tires

The idea is that over-inflating the tires will allow your car to have less surface area in contact with the road, which could improve gas mileage. However, there is no corroborating evidence. In fact, by over-inflating your tires, you’ll be causing uneven wear that could hinder fuel economy later on.
