How big is the gas tank on a 2022 GMC Sierra 1500?

Your 2022 GMC Sierra 1500’s gas tank size depends on its configuration. Between eight trim levels, three cab configurations, three bed lengths, and four engines, there are plenty of options!

Most of these configurations include a 24-gallon tank, but the Sierra 1500 models with a long truck bed hold a 28-gallon tank.

How to check your 2022 GMC Sierra’s gas tank size

There are a few different ways to confirm the gas tank size of your specific trim level and configuration.

Check your owner’s manual

You should be able to find information about your model’s fuel tank capacity under the “Capacities and Specifications” section listed in the “Technical Data” chapter of your owner’s manual. If it’s not there, you might have to browse through the manual to find more information about the gas tank.

Measure the gas tank

For a more hands-on approach, measure the width, length, and height of your tank in inches. Multiply those three figures together, then divide by 231 to get the capacity in gallons.

Drive till empty, then fill it up

As a last resort, you can wait to fill up your tank until the fuel gage hits “Empty,” then take note of how much gas you’ve purchased. Obviously, this is a risky move, so don’t plan on driving too long on empty!

How to save on fuel costs in the 2022 GMC Sierra 1500

Gas prices can fluctuate like crazy. One constant will be the large size of your gas tank if you’re driving a pickup truck. If the fuel economy numbers of the 2022 GMC Sierra 1500 worry you, here are a few tips on how you can save on your fuel costs.

First, be sure to maintain your car. Keeping everything in tip-top shape can help to ensure that your truck is running at its best at all times. Issues with your engine that go unchecked can lead to a dip in fuel economy.

Second, be a careful driver. Harsh acceleration can have an adverse effect on your truck’s fuel economy. Easing off the gas a little bit can lead to some extra money in your pocket.

Finally, avoid idling. A truck running with nowhere to go just uses up gas. When warming up your truck on a chilly day, it can be better to cut down on the idling time and instead drive the truck easily to help it warm up.

This app is great, but the customer service is even better! Not to mention convenient! My husband and I got the lowest rate (much lower than the rates I was finding online through my own searches), quickly, and pretty much all through text message! Thank you so much for a hassle free experience👍
