How big is the gas tank on a 2013 Nissan Altima?

The 2013 Nissan Altima comes in a variety of trims, with a variety of engine options available. Which engine you choose, however, has no effect on your vehicle’s gas tank size, but which body style you choose (coupe or sedan) does.

How to check your 2013 Nissan Altima’s gas tank size

If you’re still not sure of your Nissan Altima’s fuel tank capacity, there are a few ways you can check it yourself: 

Check your owner’s manual

This option should be the most obvious, as your Nissan owner’s manual is a holy grail of information. Head to the index and look for phrases like “gas tank” and/or “fuel tank capacity.”

Measure the gas tank

Do you remember middle school geometry? To calculate the volume of your gas tank, multiply its width, length, and height. Divide the result by 231 (the number of cubic inches in a gallon), and you’ve got your answer!

Drive till empty, then fill it up

Simply drive around until your gas tank is on “E,” and then fill it up until it hits “F.” The gas pump will tell you just how much gas you were able to fit.

How to save on fuel costs in a Nissan Altima

When you purchased your 2013 Nissan Altima, it had a fuel economy rating of up to 27 mpg in the city and 38 mpg on the highway.
Over the years, however, basic use can cause your fuel economy to shrink. Fortunately, there are a few ways to save on fuel costs, regardless of the age of your vehicle:
  • Keep up with maintenance. Performing regular oil changes, tire rotations, and other basic and routine maintenance is absolutely essential for maintaining your vehicle’s optimal fuel efficiency.
  • Drive carefully. Speeding isn’t only dangerous. It also burns through your gas faster than accelerating slowly and steadily.
  • Avoid idling, especially in cold weather. Contrary to popular belief, warming up your car in the winter can actually do more harm than good. Instead, start your vehicle and drive gently until the engine reaches normal operating temperature.

How to optimize your Altima’s insurance coverage

Just like gas prices, car insurance rates tend to fluctuate, so shopping around for policies periodically is the best way to make sure you’re getting the best price. And the easiest way to do that? With
