How big is the gas tank on a 2015 Honda Pilot?

How to check your 2015 Honda Pilot gas tank size

If you are still having issues finding the gas tank capacity for your 2015 Honda Pilot, don’t worry. Here are three ways to figure it out!

Check your owner’s manual

Whip out your trusty owner’s manual and look for phrases in the index or glossary such as fuel tank capacity and you should find your answer.

Measure the gas tank

Grab a tape measure and calculator, and then measure and multiply the tank’s width, height, and length. Now, take that number and divide it by 231 (the number of cubic inches in a gallon). Once you’ve done that, you’ve measured your gas tank!

Drive till empty, then fill it up

You could also go the baller route and just drive until your gas gauge hits “E” and your tank is empty. Head over to the gas station and take note of how many gallons you need before your tank is full. Granted, this won’t be an exact determination of your gas tank’s capacity, but it will be a relatively accurate approximation of how much gas your tank can hold.

How to save on fuel costs in a Honda Pilot

Your 2015 Honda Pilot has a fuel efficiency of 17/24/19 mpg (city/highway/combined), which is decent. However, there are a few ways you can stretch your gas dollar and your Pilot’s fuel efficiency even more.
  • Keep up with maintenance: This is a big one—take your Pilot in for
    regularly scheduled maintenance
    appointments to ensure it runs smoothly and to maximize fuel efficiency.
  • Drive carefully: As much as possible, keep your ride safe and smooth—avoiding sudden braking or acceleration and not driving aggressively will help you keep your Pilot’s fuel economy from slipping.
  • Avoid idling, especially during the winter: Idling your vehicle wastes gas—if you want to warm your car up on a cold day, idle for one minute and no longer, and then start gently driving. You don’t need much more than that to quickly warm up your car.
