How big is the gas tank on a 2018 Ford F-150?

The larger your cab size, the larger your gas tank size—at least when it comes to the F-150. Ford has made its 2018 F-150s to hold 23, 26, or 36 gallons of gas based on whether you’ve got a Regular, Extended, or Crew Cab. 
On all Regular Cab F-150s, you can expect to have the lowest tank size of 23 gallons. The models with Extended Cab trims also boast the same capacity, except for the Raptor Extended Cab which you can get with a 26-gallon gas tank. 
Like to take friends along on your truck rides? The Crew Cab styles found on the Ford F-150 XL, XLT, Lariat, King Ranch, Raptor, Platinum, and Limited all hold a total of 26 gallons. 
That leaves us with the lineup’s giant that holds a heavy 36 gallons of gas—the Raptor Crew Cab. If driving fills most of your days, opt for this beast. 

How to check your 2018 Ford F-150’s gas tank size

If you would rather pinpoint the exact tank size of your F-150 yourself, we’ve got solutions. Here are three methods to double-check your gas tank’s capacity: 

Measure the gas tank

If you’ve got a measuring tape and calculator at home—you can find out your gas tank’s volume easy peasy! Multiply your tank’s length, width, and height, then divide that total by 231 (the number of cubic inches in a gallon), and you’ve got your tank size.

Check your owner’s manual

Get it right from the source: dust off your owner’s manual from the glove compartment and find any mention of “fuel tank capacity” or related terms. You’ll likely find the exact number of gallons your F-150 holds! 

Drive till empty, then fill it up

If you can’t measure your gas tank or find your owner’s manual, we’ve saved one last foolproof method for you. Drive until your fuel level hits “E” and get to the nearest gas station ASAP! Once you fill up, check the meter on the fuel pump—you’ll see the magic number for how many gallons it takes to get a full tank.

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

The F-150 reaches 22 mpg combined city/highway, which is average for a pickup truck. Unfortunately, average isn’t doing much to save you costs, especially with rising gas prices. Does that mean you’re stuck throwing cash at the pump? Nope!
Lucky for you, there are other ways to save. Here are a few things you can do to make space in your car budget:
  • Drive with caution. You can’t control gas prices, but you can control how you drive! If you accelerate slowly and drive at a steady pace, your F-150 will use less fuel than if you drive erratically. 
  • Follow your maintenance routine. Even if your truck is immaculate, you’ll want to come to those scheduled check-ups to maintain fuel efficiency. When your truck is running its best, it will use the least amount of gas.
  • Don’t idle. While you may not be driving, idling still uses up gas. Make sure to turn your car off when it’s not in use.
