How big is the gas tank on a 2016 Nissan Altima?

The gas tank on a 2016 Nissan Altima can carry a maximum of 18 gallons of gasoline, no matter which version of the 2016 Altima you have.

That’s right! It makes no difference whether you have a base model Altima, an S, SR, SV, or SL, and it doesn’t matter whether you have the regular 4-cylinder engine or the upgraded V6—every 2016 Nissan Altima produced for American markets was built with an 18-gallon gas tank.

How to check your 2016 Nissan Altima’s gas tank size

We can’t help but wonder if maybe you don’t believe us—perhaps you’d like to find the answer to this pressing question using a more hands-on approach. Well, we’ve got you covered with three foolproof ways of finding out how much gas you pump into any car!

Check your owner’s manual

Boy, do we ever like this one! Your owner’s manual should have all the information you need about your car’s gas tank, including its size. If you’ve lost your owner’s manual, check your automaker’s website for an online edition.

Measure the gas tank

Could we interest you in a bit of math? Don’t worry—you don’t have to be Carl Friedrich Gauss to find the volume of a rectangular prism. There’s a simple formula for that! If you want to find the volume of the rectangular prism that is your vehicle’s gas tank, all you have to do is measure the length, width, and height of it, multiply those numbers together, and voila!

To convert your answer from cubic inches to gallons, just divide by 231! Here’s a formula to help you visualize this complex mathematical procedure:

W x L x H = V(cu in)

V(cu in) / 231 cu in = V(gal)

Drive till empty, then fill it up

In the case that you can’t be bothered to look for your owner’s manual or do some math, perhaps you can try the old “empty the tank and then fill it” trick.

That’s right. If you drive your Altima till its gas gauge reads “empty,” then you’ll be able to fill it all the way back up and take note of how much gas you filled it with, giving you a solid idea of your car’s fuel capacity.

How to save on fuel costs in a 2016 Nissan Altima

If you’re driving the Altima with the base 2.5-liter I-4 engine, you’re already probably saving plenty on fuel costs—this engine gets 27 mpg in the city and 39 mpg on the highway. But there’s more you can do to save money on gas besides driving a fuel-efficient vehicle:

Keep up with maintenance. Sticking to a regular

car maintenance schedule

will reduce wear-and-tear on your engine and prevent a slow loss of efficiency.

Drive carefully. If you’re used to gunning it when the light turns green, you’re probably wasting a lot of gas. Try easing up there, Brickfoot!

Avoid idling. Idling is a surefire way to waste gas, and you look silly when you do it.
