A gas-guzzling SUV isn't easy to maintain. When fuel prices are high, you may be tempted only to fill up the gas gauge three-quarters, half, or a third full. In these cases, it’s handy to know the size of your car's gas tank.

How big is the gas tank of a 2021 Dodge Durango?

It doesn't matter what trim or engine you choose, the 2021 Dodge Durango comes with a 24.6-gallon gas tank.

In most models, that's not the case. Higher

trim levels

tend to get bigger tanks because more powerful engines tend to consume more gas. And as you can see in the table below, the Durango’s four powertrains deliver four very different performances:

Gas tank size	Trims	Engine	Horsepower	Torque
24.6 gal	SXT, GT, Citadel	3.6L V6	295-hp	260 lb-ft
24.6 gal	R/T, Citadel (optional)	5.7L V8	360-hp	390 lb-ft
24.6 gal	SRT	6.4L V8	475-hp	470 lb-ft
24.6 gal	SRT Hellcat	6.2L supercharged V8	710-hp	645 lb-ft

How to check your 2021 Dodge Durango’s gas tank size

Not sure of your car’s trim? Its engine? Or even its model year? There are other ways to find out the size of your car’s gas tank—here are three of them:

Measure the gas tank

All this takes is some measuring tape, a calculator, and some effort. First, find your vehicle’s gas tank and measure its width, length, and height in inches. Next, multiply the measurements together and divide the result by 231 (the number of cubic inches in one gallon). The result is your car’s gas tank size!

Check your owner’s manual

Your SUV’s owner's manual should also tell you how much gas it can hold, along with

how to choose the best gasoline or fuel

to keep it running.

MOPAR

offers a digital manual for every Durango if you can't find yours. But how do you know which one you have?

Simple: visit the

NHTSA's decoding website

and enter your car's VIN, which you can find on the driver's-side windshield or on your

proof of insurance

). The results will include your vehicle's model year, trim, and engine size.

Drive ‘til empty, then fill it up

This one’s a little risky—it’s time to find out

how far you can drive on an empty tank of gas

. If you time it right, you’ll end up at the gas pump, and all you have to do is note how many gallons it takes to refuel your SUV. If you time it wrong, you’ll have to start thinking about the average

cost for a tow

instead, so we don’t recommend it.

How to save on fuel costs in a Dodge Durango

While the SRT Hellcat might win a race from 0-60 mph (in 3.6 seconds), it ranks dead last for fuel economy. Considering that it also uses premium gas (compared to the 5.7L V8, which uses midgrade, or the 3.6L V6, which uses regular), driving such a powerhouse can add up fast.

Every powertrain gets the following mileage:

Trims	Engine	Transmission	Drivetrain	Miles per gallon (combined/city/highway)
SXT, GT, Citadel	3.6L V6	Eight-speed automatic	RWD	21/19/26 mpg
R/T, Citadel (optional)	5.7L V8	Eight-speed automatic	RWD	17/14/22 mpg
SRT	6.4L V8	Eight-speed automatic	AWD	15/13/19 mpg
SRT Hellcat	6.2L supercharged V8	Eight-speed automatic	AWD	13/12/17 mpg

It can help to adjust your driving habits to keep your Hellcat and your wallet happy. To increase the time between gas station visits, follow these tips:

Make sure your vehicle is maintained regularly. By servicing your car and following a regular

maintenance schedule

, you keep it running smoothly as well as efficiently.

Step off the gas. Stepping on the gas pedal increases gas consumption! Take your time and accelerate gently instead.

Put on a parka. Even if you hate the cold, idling and waiting for the cabin to warm up wastes a lot of gas. Instead, try driving around to gradually warm up your vehicle.
