The gas tank size on the 2009 Nissan Altima is pretty straightforward—every trim configuration came with the same 20-gallon gas tank.
For some of us, filling up the gas tank used to mean collecting change from the couch cushions. Recently, though, keeping a full tank has become part of a monthly budgeting strategy that requires knowing not only how much the current gas price per gallon is but also how much your tank can hold.
This information is always in your car’s owner’s manual, but you may not always have easy access to that anymore. Instead look to

How big is the gas tank on a 2009 Nissan Altima?
Every 2009 Nissan Altima is equipped with a 20-gallon gas tank, which is well over the average 13-gallon capacity of most sedans that year.
How to check your 2009 Nissan Altima’s gas tank size
You can check your 2009 Nissan Altima’s gas tank on your own for some additional reassurance—here’s how!
Measure the gas tank
We hope you won’t mind getting dirty because you’ll be crawling under your car for this one. Grab a measuring tape and a calculator and prepare to do a little basic math.
To get your fuel tank’s capacity, multiply the width, length, and height, then divide the result by the number of cubic inches in a gallon, which is 231. Viola—that’s your gas tank’s volume in gallons!
Check your owner’s manual
Your Altima’s got some years on it, but hopefully, the owner’s manual is still in the glove compartment. Your tank’s fuel capacity will be listed under something simple, like “fuel tank capacity.” If the manual isn’t in the glove box, you can look it up online.
Drive till empty, then fill it up
After being cooped up for lockdowns and quarantines, you may be looking for a little adventure—so here’s another, more exciting way to find your gas tank’s capacity. Drive until your Altima’s tank is empty, then fill it up. Logic and physics dictate that when your tank is empty, the number of gallons you can fill it with is the number of gallons it’ll hold, so, voila!
How to save on fuel costs in a Nissan Altima
Today, the average sedan’s EPA-rated combined fuel economy is 26 mpg. The Altima achieved this average way back in 2009, but it may not get the same great gas mileage 13 years later. Here are a few tips for keeping your Altima in peak performance:
Stay on top of maintenance. Whether you’ve been the only owner or you bought your Altima used, there’s a chance it hasn’t always been kept up as far as a basic
car maintenance schedule is concerned. Getting it on a regular schedule now is one of the easiest and best ways to get and keep your Altima running at peak efficiency.
Drive carefully. The best way to ruin your Altima’s gas mileage is to ride the accelerator. Go easy on the gas and follow posted speed limits to maximize your Altima’s and any vehicle’s performance and fuel economy.
Avoid idling, especially in cold weather. No matter the weather, warming up your car in Park wastes a lot of gas. Drive gently to get your engine up to speed and up to heat—and maybe bring an extra layer to start.
How to optimize your Altima’s insurance coverage
Pulling up to the pump has become one of the more stressful parts of the day for many of us, even with a fuel-sipper like the Altima. While we may not be able to completely forego the cost of fuel, there are lots of ways to save money on other car-related expenses—like your
