How to check your 2018 Honda Accord’s gas tank size

Of course, you may want to be extra sure of your Honda Accord’s gas tank size, so you could always use one of these three alternative methods to find the answers above the hard way!

Measure the gas tank

We get it! You like math!
Well, you’re more than welcome to take out a measuring tape and measure the exterior dimensions of your Accord’s gas tank. Multiply the length, width, and height together to calculate the tank’s volume, and then do a simple little conversion to convert that number from cubic inches to gallons by dividing by 231. Here’s a formula to help you out!
  • W x L x H = V
  • V(cu in)(1 gal/231 cu in) = V(gal)
If the math option seems like a lot of extra work to find the answer we already googled for you, you might be right! But you have other options!

Check your owner’s manual

Ah yes, the fabled owner’s manual, the holy grail of information on your particular car—a whole textbook rife with knowledge, wisdom, and diagrams. We’re willing to bet you’ll find your car’s fuel capacity in there!

Drive till empty, then fill it up

Those of you who are living for the hustle might not have time to measure your gas tank or even take time out of your day to read an owner’s manual, but you’ll have to fill up your gas tank again eventually, right? Well, why not just wait until your gas gauge is on empty and then fill your car up all the way to full?
All you’ll have to do is take note of how many gallons were required to fill it up and you’ll have a solid estimate on your vehicle’s fuel capacity!

How to save on fuel costs in a 2018 Honda Accord

The best way to save the most on fuel with a 2018 Honda Accord is by choosing one with a hybrid drivetrain! The 2018 Honda Accord Hybrid gets 47 mpg in both city and highway settings, while the CVT automatic paired with the base 1.5-liter turbo I-4 allows for 30/38 mpg city/highway.
If you don’t have one of the more efficient 2018 Accord models, you can always save on fuel by practicing good habits like these:
  • Keep up with maintenance. You can find a schedule for all the regular maintenance your vehicle needs in that magical owner’s manual we’ve been mentioning! When your car is running its best, it tends to be more fuel-efficient.
  • Drive carefully. If you slam on the gas pedal, it’ll feed a ton of gas into the engine. That makes you go very fast, but you’ll also consume a whole lot of gas in the process. Ease up for more fuel savings.
  • Avoid idling. If you want to save gas, don’t let the engine idle. Instead, turn off the engine, then turn it back on again when you’re ready to drive.
