How big is the gas tank on a 2015 Nissan Altima?

With a perfect balance of power, safety, and fuel efficiency, the 2015 Nissan Altima is an ideal family sedan if you’re looking to buy a used car. And as a bonus, all of the trims for this model year have the exact same gas tank size: 18 gallons.

Here are all of the trims offered in the 2015 Altima lineup:

2.5

2.5 S

2.5 SV

2.5 SL

3.5 S

3.5 SV

3.5 SL

You’ll have your choice of a 2.5L 4-cylinder engine or a 3.5L V6 engine, each paired with

a CVT automatic transmission

. But don’t be fooled by the liter measurements—these values indicate the volume of the engine itself, not the size of your gas tank. Regardless of engine type, your Altima gas tank will still hold 18 gallons.

How to check your 2015 Nissan Altima’s gas tank size

Not sure if 18 gallons lines up with your Altima’s gas tank size? Here are a few easy methods to confirm the size of your gas tank and plan for your next trip to the gas station.

Measure the gas tank

If you need to see it to believe it, you can physically measure the gas tank quite easily. Gather up a measuring tape and a calculator and multiply the tank’s width, length, and height. Divide this value by 231 (that’s the number of cubic inches in a gallon) to get the size of your gas tank in gallons.

Check your owner’s manual

Your owner’s manual will have the official capacity for your gas tank. Check the table of contents or the index for “fuel tank capacity” or similar phrases to find an accurate measurement straight from the manufacturer.

Drive till empty, then fill it up

As a last resort, you can drive until the fuel gauge on your Altima hits “E” and then fill it up. This method is far from precise, but it’ll give you a ballpark idea of your gas tank capacity. Just make sure you can get to a gas station on time!

How to save on fuel costs for a 2015 Nissan Altima

With the base engine, the 2015 Nissan Altima has an EPA-estimated fuel efficiency of 31 mpg combined (27 city/38 highway). The V6 engine falls a little bit behind at 26 mpg combined (22 city/32 highway)—still impressive numbers nonetheless!

Even though the Altima is an excellent choice for the fuel-conscious, there’s nothing wrong with saving a bit extra on gas costs! Here are some tips to knock a few bucks off your gas bill:

Perform regular maintenance. Catching small issues and staying on top of scheduled maintenance keeps your car functioning at its most efficient capacity, which will save you a bundle on gas and repair costs.

Drive steadily. Stopping and starting suddenly can eat away at gas. Be mindful when accelerating to help save at the pump.

Don’t idle, even in cold weather. Warming up your car is important, but idling in the driveway wastes precious fuel. Instead, try driving the vehicle slowly to warm up the engine.
