Pickup trucks like the famous F-150 need a lot of gas to run, especially if they’re used for towing or hauling heavy cargo, so they tend to have pretty big gas tanks. Since they’re used for work, play, and everything in between, they come in a variety of sizes and configurations that help determine their tank size.

How to check your 2015 Ford F-150’s gas tank size

Here are two other ways to check your tank’s size:

Check your owner’s manual

This is the easiest way if you still have your truck’s manual—just look for a phrase like “fuel tank capacity” in the index, then flip to the appropriate section. Manuals are available online, too.

Measure it yourself

If you have a measuring tape and can get under your truck, you can measure the size of the gas tank yourself. To get the correct capacity, just multiply the width, length, and height of the tank and divide the result by 231, the number of cubic inches in a gallon.

How to save on fuel costs in a Ford F-150

The 2015 F-150 was the first of its kind with a body made primarily of aluminum alloy, which made it almost 500 pounds lighter than previous models. This increased its towing capacity, but more importantly, made it slightly more fuel-efficient: 
Only slightly, though—the 2015 F-150 is rated for about 19 mpg in the city and 26 on the highway, but there are a few ways to maximize efficiency and minimize fuel costs:
  • Keep up with maintenance: Fuel efficiency will almost certainly dip if your truck isn’t regularly maintained. 
  • Drive carefully: Constantly flooring the gas pedal will burn much more fuel than driving gently and carefully.
  • Keep your tires inflated: Tires filled to the proper level of air pressure will get you the best gas mileage.
  • Don’t overload it: A heavier truck needs to burn more fuel to run, so keeping a bunch of heavy stuff in it will hurt its fuel economy.
