How big is the gas tank on a 2018 Honda CR-V?

The 2018 Honda CR-V comes with a 14-gallon fuel tank regardless of trim level or engine type.
That said, there are two engine types: 1) the standard 2.4-liter 4-cylinder and 2) the 1.5-liter turbocharged inline-four. Among all options, the 1.5-liter engine with FWD has the best fuel economy of the lot. 

How to check your 2018 Honda CR-V’s gas tank size

Checking your CR-V’s gas tank capacity is easier than you might think. Here are a few tricks you can take with you to the pump.

Measure the gas tank

This method is perhaps the most hands-on but provides a great opportunity to get to know your CR-V inside and out. Just grab a measuring tape and jot down the width, length, and height of the tank. Multiply those numbers, then divide the answer by 231 to convert cubic inches to gallons — that’s your gas tank’s capacity.

Check your owner’s manual

Maybe you don’t have online access, your phone’s dead, or you’re otherwise unable to use the internet as a resource. Thankfully, your fuel tank information can be found the old-fashioned way: by looking in the owner’s manual. 
You should be able to find this data rather easily in the quick reference guide at the front of the booklet. Look for “fuel tank capacity”, “refueling”, and related terms. You can also find this information listed under vehicle specifications

Drive till empty, then fill it up

If you don’t have a measuring tape and you can't find your owner’s manual, you can estimate your gas tank size by driving until the low fuel indicator light comes on, which will be when there are about 2.1 gallons left in your CR-V’s reserve.
Next, drive to the nearest pump to fill up your tank to get a rough idea of how much gasoline your car needs. Be careful not to push off refueling for too long — running out of fuel can cause your engine to misfire, which damages the catalytic converter.

How to save on fuel costs in a Honda CR-V

All things considered, the 2018 CR-V gets surprisingly good fuel economy. The base 2.4-liter engine with FWD offers 26 mpg in the city and 32 mpg on the highway, but if you want to maximize your fuel efficiency, you can slightly bump up your efficiency to 28 mpg/city and 34 mpg/highway by selecting the 1.5-liter engine/FWD configuration.
By modern standards, the 2018 CR-V’s fuel efficiency is not ideal and will quickly fall behind as alternative power technologies improve, which doesn’t bode well for your wallet when also considering rising fuel prices. Fortunately, you can scale back on your fuel consumption and save some money with these tips: 
  • Keep up with a
    maintenance schedule
    . If your CR-V regularly goes without routine care, your fuel economy can easily dip. 
  • Drive carefully. Don’t stop and go suddenly. This will help prevent excess fuel consumption.
  • Avoid idling, particularly in chilly weather. Idling is wasteful for no good reason. Ease into your drives on cold winter mornings rather than running your car in your driveway.
