Canyon gas tank sizes fluctuate based on the model year of your truck. Although the gas tank size hasn’t changed drastically in its 17 years of production, it’s good to know the gas tank size of your specific pickup. Earlier Canyon model years generally had gas tanks with a capacity of 19.5 gallons, while more recent models have grown to about 21 gallons.
Below is a table breaking down the different GC Canyon gas tank sizes by model year:

How to check your GMC Canyon’s gas tank size
If you’d like to verify your gas tank size for yourself, we have a few ways you can do so.
Check your owner’s manual
Your GMC Canyon owner’s manual will always be your best resource for just about anything you want to know about your truck.
Flip through the table of contents until you find the capacities and specifications section—your fuel tank capacity will lie here.
Measure the gas tank
If you’re more into math than reading, you can determine the gas tank size with a tape measure and calculator.
Measure the height, length, and width of the tank, and multiply those numbers together. Then, divide that number by 231 (the number of cubic inches in a gallon).
Drive till empty, then fill it up
If you don’t have the strength for any reading or math but are not one to shy away from a little risk, we’ve got just the method for you.
Drive your Canyon until the fuel gauge is just about to hit “E” and then completely fill up your gas tank. It won’t be exact, but the pump will give you a rough idea of how much gas your tank can hold.

How to save on fuel costs in a GMC Canyon
You probably didn’t buy your Canyon because of its fuel efficiency—its 19 combined city and highway miles per gallon isn’t exactly something to write home about. If you drive your pickup for work or personal use (or both), you could find yourself at the pump more often than you’d prefer.
Don’t worry, we’ve got your back. Consider these tips to improve your gas conservation and keep more money in your pocket:
- Stay on top of maintenance: Keeping up with general maintenance and repairs will keep your Canyon’s fuel efficiency at its highest level.
- Drive carefully: Gentle pedal operation and smooth acceleration and will keep your gas consumption low.
- Avoid idling: Let’s debunk the common myth that idling your engine is the best way to warm it up. This wastes gas and you should warm up your engine by driving slowly.
