How big is the gas tank on a 2015 Subaru Forester?

The 2015 Subaru Forester comes in six trim levels, but they all have the same 15.9-gallon gas tank. At an average combined fuel efficiency of 25 mpg, you’ll be able to cover roughly 400 miles before making a pitstop at your nearest gas station. 
Although, the “nearest gas station” is relative to how far into the wilderness you plan on driving. That’s why knowing the exact size and capabilities of your gas tank is so important.

How to check your 2015 Subaru Forester’s gas tank size

If you want to verify this information for yourself, there are multiple ways you can double-check the size of your 2015 Subaru Forester’s gas tank.

Measure the gas tank

Believe it or not, you can manually measure the size of your gas tank. Start by grabbing your trusty tape measure and locating the tank on the underside of the vehicle. Then follow these instructions:
  • Measure the tank's width, length, and height
  • Multiply the three measurements together
  • Divide the result by 231 (cubic inches in a gallon)
If your measurements are accurate, your calculator should reveal 15.9 gallons as your answer!

Check your owner’s manual

You may have to dig through your glove compartment, but all the questions you could ever ask are answered in your Subaru Forester’s owner’s manual. Browse the index to locate “fuel tank capacity” or similar phrases to find the right page.

Drive till empty, then fill it up

This is a bit risky, but you can run your gas tank nearly dry and measure the number of gallons it takes to fill it back up. Obviously, only try this in an urban setting where there are plenty of gas stations—not when you’re out in the wilderness.

How to save on fuel costs in a 2015 Subaru Forester

The average driver gets a combined 25 mpg out of their 2015 Subaru Forester, but you’re not average! Here are a few intuitive strategies you can implement to bump those numbers up and save on fuel costs:
  • Keep up with maintenance. Following a
    regular maintenance schedule
    can prevent unnecessary wear and tear and keep your Subaru Forester running smoothly.
  • Limit off-roading. The occasional off-roading is fine, but too much can expedite wear and tear and decrease fuel efficiency.
  • Drive carefully. Being easy on the accelerator can help optimize your fuel efficiency.
  • Apply for a tax credit. The 2015 Subaru Forester can come as a PZEV (Partial Zero Emission Vehicle—the cleanest-running gasoline-powered car), which may qualify for a state tax credit.
  • Avoid idling, especially in cold weather. You may hear complaints from your fellow campers, but gently driving your vehicle is a much more fuel-efficient way of warming up the engine.
