How big is the gas tank on a 2021 GMC Yukon Denali?

The 2021 Yukon Denali’s gas tank size is 24 gallons—unless it’s a

GMC Yukon XL Denali

, in which case the fuel capacity is 28 gallons

The Yukon Denali transformed in recent years from a sub-brand to a star in its own right, taking up the lucrative middle ground that used to be occupied by the

Cadillac Escalade

. It’s a huge beast of an SUV and comes with one of two engines: a 3.0L turbocharged diesel engine or a 6.2L V8.

Either way, the gas tank size is 24 gallons. That means, one tank will last a maximum of 360 miles of city driving and 480 miles of highway driving.

The Yukon XL Denali, on the other hand, has a larger tank that holds 28 gallons, taking the driving range up to a potential 420 miles of city driving and 560 miles of highway driving.

No matter which you go for, you can tackle the open highway without worrying too much about where the next gas station is.

How to check your 2021 GMC Yukon Denali’s gas tank size

If you’re still not sure how many gallons your 2021 GMC Yukon Denali’s tank can accommodate, don’t worry. Here’s how to find out.

Check your owner’s manual

The easiest way to figure out your gas tank size is to check what it says in your owner’s manual. In the GMC Yukon Denali manual, you should be able to find this info on page 397 under Vehicle Data.

Measure the gas tank

You can always take matters into your own hands, instead, with the help of a measuring tape and a calculator. To get the correct capacity, just multiply the width, length, and height of the tank and divide the result by231 (the number of cubic inches in a gallon).

Drive till empty, then fill it up

The most extreme way of finding out your gas tank’s approximate capacity is to drive until your fuel gauge reads empty, then head to the closest gas station. When you’re pumping gas, the display shows how much you’re putting in. Note the number of gallons you purchased once your tank is full.

Of course, there are lots of downsides to this approach. For one thing, you need to be careful you don’t end up stranded because you waited too long. And secondly, it’s not a very scientific method unless you really are running on fumes (which is pretty foolish and not recommended). But it’s certainly an exciting experiment…

How to save on fuel costs in a GMC Yukon Denali

With a regular gasoline engine and four-wheel drive, the 2021 GMC Yukon Denali is rated for about 15-20 mpg combined city/highway, with minor variations for engine choice.

This means that it’s not exactly an economical vehicle to drive, even if it’s not one of the worst offenders when it comes to fuel efficiency. Fortunately, there are steps you can take to avoid pouring your wages into the gas tank:

Drive carefully. We get it. GMC Yukons are fun to drive, especially on the open highway. But if you ease up on the gas pedal and avoid harsh acceleration, you’ve got a better chance of keeping your fuel consumption down.

Skip idling. If you live somewhere cold, those frosty mornings can be a nuisance. But instead of turning your car on to let it warm up and defrost, scrape the windshield and drive off. Otherwise, you’re just wasting gas for nothing—and who can afford to do that?

Stay on top of maintenance. Car maintenance isn’t always cheap, so it may be tempting to skip it. However, wear and tear can start to impact performance and tank your fuel economy if left unaddressed.
