How big is the gas tank on an Infiniti QX80?

All Infiniti QX80 models, regardless of the model year, have a 26-gallon gas tank.

Something else that the QX80s have in common? Their 400-hp 5.6-liter V-8 engine. The 5.6-liter measurement doesn’t refer to the amount of gas in the engine, but rather how much space the engine takes up—make sure you don’t confuse the two measurements, otherwise your fuel estimates will be way off!

How to check your Infiniti QX80’s gas tank size

Nothing wrong with double-checking the facts, especially the ones you find online. Here are a few ways you can confirm the size of your QX80’s gas tank.

Manually measure the gas tank

Time to bust out that old calculator and measuring tape! Nothing is stopping you from getting underneath your car and manually measuring your gas tank. Infiniti QX80 gas tanks are generally near the rear of the vehicle.

To calculate your gas tank capacity, measure the width, length, and height of the tank and multiply them together. To get the answer in gallons, divide the result by 231.

Check your owner’s manual

Your owner’s manual is the go-to source for information about your QX80. Check the table of contents or the index for terms like “fuel tank capacity” to find the manufacturer’s measurement of your gas tank.

Drive till empty, then fill it up

If you don’t have time to measure your tank and you’ve misplaced your owner’s manual, there’s one more way you can check the size of your gas tank: by how much gas it takes to fill it up! Drive until your car is close to empty, then take note of the gallon measurement on the pump once your car is full.

This method won’t provide an exact answer, but it’ll give you a ballpark idea of how much gas you can fit in your tank. Just don’t drive too long on empty, or you may end up needing a tow.

How to save on fuel costs in an Infiniti QX80

The Infiniti QX80’s 5.6L V-8 engine doesn’t do so well when it comes to fuel economy. The EPA rated the 2023 model for 14 mpg in the city and 20 mph on the highway. Compared to rivals like the

BMW X7

(21/26 mpg), the QX80 is a gas guzzler.

There are still ways you can optimize your fuel economy! Here are some easy steps you can take right now to save on gas prices:

Perform regular maintenance. If your QX80 is running in peak condition, it will use fuel more efficiently.

Ease off the accelerator. Keep your driving speed smooth and steady to keep your fuel consumption steady too!

Avoid idling. Running your car while you’re waiting for your kid to get out of dance class is burning precious fuel. Even in cold weather, it’s better to gently drive your car to warm it up instead of letting it idle in the driveway.

How to optimize your QX80’s insurance coverage

As a luxury vehicle, the QX80 isn’t cheap to maintain. Between gas prices, car maintenance, and car insurance, ownership costs can get a little pricey. But with
