How Many Gallons Does the 2023 GMC Sierra 1500 Hold?

There are many factors you should consider when exploring a new truck. For example, you’ll want to make sure it has enough seats, a large enough truck bed, or the ability to tow your trailer. You may also want to consider fuel efficiency and how far you can drive on a single tank of gas. After all, gas is expensive, which is why fuel costs are a major part of truck ownership.

With that in mind, below we’ll provide some details on the tank sizes that you can find in the popular 2023 GMC Sierra 1500, along with what sort of fuel efficiency you can expect. We’ll also provide some tips on how to improve fuel efficiency so that you can save money at the pump.

How To Improve Fuel Efficiency

Regardless of what sort of vehicle you’re driving, there are a few things you can do to improve fuel efficiency. Implementing the tips below can help you get further on a single tank of gas, thereby saving you money in the long run.

Reduce Weight

One simple place to start is by reducing the weight of your vehicle. The heavier your vehicle, the more your engine has to work to power it, which uses more fuel. If you can reduce the weight by removing things you don’t need, you’ll find that you don’t use as much fuel. For example, you can remove items such as roof or bike racks when you’re not using them. Also, look to remove cargo from your truck bed when you can, rather than leaving it in there for extended trips.

While there aren’t many ways to significantly reduce the weight of your vehicle, if you can limit your extra items, this will pay off over time.

Change Driving Habits

Your driving habits also play a big role in determining your fuel efficiency. For instance, vehicles start to lose fuel efficiency after reaching about 45 to 50 mph. The more you go over this speed limit, the less efficient your engine becomes. Therefore, if you can stay closer to the speed limit when driving, you’ll improve your fuel efficiency.

The same goes for how you drive. Repeated acceleration and hard braking use up more fuel. Instead, try to cruise at a steady pace, using cruise control when possible. The 2023 GMC Sierra 1500 features optional adaptive cruise control, making driving not only more enjoyable but more fuel-efficient.

Limit Idling

Idling is another big user of gas. In fact, idling uses more gas than if you were to turn off your vehicle and restart it. Therefore, the next time you’re going to be waiting in your vehicle for an extended period of time, consider shutting it off rather than letting the engine run. This will not only help you save on gas money but it’s better for the environment too.

Perform Regular Maintenance

Finally, make sure you’re performing regular maintenance on your vehicle. There are many components inside your vehicle, and some of them can begin to impact fuel efficiency if you don’t take care of them. For example, dirty air filters make it harder for the engine to run efficiently, meaning that it uses more fuel. Other parts to be aware of are your spark plugs and oil.

One especially important area to pay attention to is your tires. If your tires are underinflated, they can increase your fuel consumption by up to 3%. With underinflated tires, therefore, you’re not only using more gas but decreasing the life of your tires, meaning that you’ll need to replace them sooner. You can check your owner’s manual to learn the proper inflation amount for your tires.

With your internal components and tires both impacting fuel efficiency, we recommend that you bring your vehicle in for maintenance every few thousand miles. Doing so not only improves fuel efficiency but also extends the life of your vehicle and can help you avoid costly repairs.
