5 Shocking Myths About Gas Mileage

Every person has their methods and beliefs on how to get the best gas mileage. It's pretty tricky to know what holds true and what doesn't. STR Automotive is here to set the record straight -- we're going to be debunking some common myths about gas mileage that may shock you!


Myth #1: You have to drive a small car to get good fuel economy.

Advancements in the automotive industry such as hybrids, diesel engines, direct fuel injection, turbocharging, advanced transmissions, and low rolling resistance tires enable mid-sized vehicles to be very fuel economical. In 2014, about half of the top 10 most efficient vehicles were midsize or large cars.


Myth #2: It takes more gas to start a car than it does to let it idle.

Modernized engines start more efficiently. Idling can use a quarter to a half-gallon of gasoline per hour, which comes out to be around 1 to 2 cents a minute. Instead, turn off your engine when your vehicle is sitting still to save you those coins.


Myth #3: Using premium fuel improves fuel economy.

Unless the manufacturer explicitly recommended your car to receive premium fuel, you will probably experience no extra benefits from using premium fuel over regular. 


Myth #4: EPA fuel economy estimates are a guarantee of what mileage an automobile will deliver.

The primary objective of EPA fuel economy estimates is to inform the public with a uniform and unbiased way of comparing the efficiency of vehicles. Even though the EPA's test methods are designed to show driving conditions, no tests in the world can't accurately model all driving styles and environments. 


Myth #5: Filling up when it's cooler gets you more gas

For years, this myth has persisted: you get a bang for your buck if you buy gas in the coldest part of the day since cooler fluid is denser. However, gasoline is almost always pumped from storage tanks stored underground that are insulated from temperature fluctuations at gas stations.
