How big is the gas tank on a 2015 Ford Explorer?

The 2015 Ford Explorer is a mid-size crossover SUV, but it’s equipped with a larger-than-average gas tank—ensuring you’ll get from point A to point B (and back again) without any issues. Regardless of trim level, your 2015 Explorer will have an 18.6-gallon tank.
This tank size remains consistent regardless of which V6 engine you select, and whether you opt for an upgraded all-wheel drivetrain.

How to check your 2015 Ford Explorer’s gas tank size

No matter what vehicle you drive, there are a few surefire ways to double-check your gas tank’s size.

Measure the gas tank

Do it the old-fashioned way with a measuring tape and a calculator! Locate your vehicle’s tank and measure the width, length, and height. Multiply these three numbers together, then divide by the number of cubic inches in a gallon—231. The result is your tank’s capacity, in gallons.

Check your owner’s manual

If you have your owner’s manual handy, you can skip the manual labor. Look for phrases like “fuel tank capacity” or “fuel tank size” in the index.

Drive till empty, then fill it up

Feeling risky? You can get a close estimate of your vehicle’s fuel tank capacity by driving around until the fuel gauge hits “E” for “empty.” Then, fill your tank all the way up to max capacity, and take a look at the fuel pump! This won’t be exact, but it’ll be pretty good estimate of the general size of your tank.

How to save on fuel costs in a Ford Explorer

An 18.6-gallon tank could cost quite a bit to fill to the brim—and since the 2015 Ford Explorer only gets an estimated 18 mpg of combined highway/city miles, you could find yourself making frequent trips to the gas station.
Fortunately, there are a few ways to save on fuel costs:
  • Keep up with maintenance. Your car will only have optimal fuel economy if it’s well taken care of. Keep up with oil changes and other routine maintenance to ensure your engine is in tip-top shape.
  • Drive carefully. Keep an eye on your vehicle’s RPM gauge—heavy acceleration causes your wheels’ RPM to jump, burning through gas much quicker. Drive carefully and accelerate slowly to save on gas.
  • Avoid idling, especially in cold weather. Even if your car isn’t moving, if the ignition is on, you’re using gas. Avoid idling, and in cold weather, heat up your car by driving it gently for the first few minutes.
