The Chevy Silverado has been a popular pickup truck for years due to its smooth ride and towing capacity. However, since trucks don't get the fuel economy that sedans do, you may want to know their fuel capacity. So let's take a look at each Chevy Silverado's gas capacity below.
The Chevy Silverado's have the following gas capacity:
- Chevy Silverado 1500 Regular Cab - 28.3 Gallons
- Chevy Silverado 1500 (Crew Cab & Double Cab) - 24 Gallons
- Chevy Silverado 2500 (Regular Cab, Crew Cab, Double Cab) - 36 Gallons
- Chevy Silverado 3500 (Regular Cab, Crew Cab, Double Cab) - 36 Gallons
As you can see, depending on what Silverado you choose will decide the amount of fuel it can hold. In this article, we will take a closer look at the gas capacity of the Chevy Silverado. In addition, we will answer other frequently asked questions about the gas capacity of the Chevy Silverado, so read on!
How Big Is The Gas Tank On A Chevy Silverado?
Vehicles like the Chevy Silverado have gas tank capacities that only hold a certain amount of fuel. For example, whether you own a Chevy Silverado 1500, 2500, or 3500, their gas tank sizes stay true to how many gallons they can hold.
Vehicle manufacturers determine the size of a gas tank by looking at how much fuel the engine needs to run. They also take into account how much space is available in the vehicle. By doing this, they can provide a gas tank that can hold enough fuel to last.
Some people attempt to deliver additional fuel after the gas pump automatically shuts off, commonly known as "topping off."
However, this isn't necessary, as the gas pump will shut off when it has reached the correct amount of fuel. Continuing to add fuel after the pump has stopped could result in spilled fuel and wasted money.
When this happens, the additional fuel fills the vapor headspace and the filler pipe, which can be sucked into the charcoal canister. As a result, this can damage your Chevy Silverado's fuel systems, causing the check engine light to come on.
So when you are filling your Silverado with gas and the fuel pump stops, you can be sure that the tank is full and there is no need to put in more.
2021 Chevrolet Silverado 1500 Fuel Tank Capacity
Unlike the Chevrolet Silverado 2500 and 3500, the Silverado 1500 gas capacity varies depending on the trim. For example, the regular cab has a tank with a total of 28.3 gallons, while the crew cab and double cab have a tank that can hold up to 24 gallons.
One possible reason the regular cab has a bigger gas tank is due to its longer bed. In addition, regular cabs are only two-door trucks, so they have more room for a larger tank.
How Far Can A Chevy Silverado Go On A Full Tank Of Gas?
Several variables come into place when determining how far any vehicle can go on a tank of gas. These factors can include the type of terrain being traveled, the weight of the vehicle, the size of the tank, and how efficiently the engine is running.
That said, the Chevy Silverado can go 260-552 miles when driving only in the city and 312-792 miles on the highway. But, of course, this depends on the flow of traffic and driving habits. Also, the trim level of the Silverado will influence the range.
For example, a Silverado with a higher engine displacement will get better fuel economy than a lower engine displacement. However, if you are looking for one with great towing capacity and a long fuel range, then Chevy Silverado 2500 or 3600 will suit you the best.
There are also ways to increase your fuel mileage. Let's take a look at them below:
Use Cruise Control
Cruise control can help you maintain a consistent speed when traveling on a highway. This will allow your engine to run at a more efficient pace and save on fuel.
Avoid Aggressive Driving
Speeding, rapid braking, and hard cornering can use more fuel than if you drive more conservatively.
Keep Tires Properly Inflated
Underinflated tires can decrease fuel efficiency. Make sure to check your tire pressure regularly and keep them at the correct levels.
If you are going to be stopped for more than 10 seconds, it is best to turn your vehicle off. When your engine is running, it consumes fuel even if you are not moving.
Use Lower Viscocity Oil
The type of engine oil that you use can also affect your fuel economy. Choosing a lower viscosity oil can help to improve efficiency.
Cold Air Intake
An aftermarket cold air intake can help to improve your engine's performance. This allows your engine to run cooler and more efficiently.
Chip Your Vehicle
Some companies offer performance chips that you can install in your Silverado. These chips can help to improve fuel economy by optimizing the engine's performance.
Follow Maintenance Schedules
Regularly scheduled maintenance can help to keep your engine running in top condition. This will help you avoid replacing expensive parts and improve fuel economy.
Free Flow Exhaust
Installing a free flow exhaust will help your engine "breath" better. This will allow it to run more efficiently and improve fuel economy.
How Big Is The Gas Tank In A 2020 Chevy Silverado?
The 2020 Chevy Silverado has the same gas tank capacity as 2021. It has a tank that can hold up to 24 gallons of gas in the double cab and crew cab.
You will increase the gas tank capacity to 28.3 gallons for the regular cab.
What Kind Of Gas Does A 2020 Silverado Take?
The 2020 Chevy Silverado runs on unleaded 87 octane gas. It can run on 91 premium fuel, but it might not make a difference in fuel economy or performance. You will also be spending more money on premium fuel.
Premium gas is usually used for high horsepower engines, usually equipped with a turbocharger(s) or supercharger. Unfortunately, a Chevy Silverado is not one of those vehicles and doesn't need premium gas to run at its best.
What Are The Signs Of Bad Gas In The Tank?
If you are experiencing any of the following symptoms, it might be a sign that you have bad gas in your tank:
- Your car is hard to start
- Your engine is misfiring
- You are experiencing reduced power
- The check engine light is on
If you are experiencing any of these issues, it is best to take your car to a mechanic and have them look at it. Bad gas can damage your engine and can be costly to repair.
In addition, the mechanic may need to flush your fuel system to remove the bad gas.
What If I Put Diesel In My Gas Tank?
If you put diesel fuel in your gas tank, you will likely damage your engine. Diesel fuel is not meant to be used in gasoline engines and can cause severe damage.
If you have put diesel fuel in your car, immediately take it to a mechanic. Do not drive it any further as it could cause even more damage.
Instead, you should pull over to a safe place and have the vehicle towed. The repairs might be expensive, but it is better than causing further damage to your car.
Does The Chevy Silverado Come In Diesel?
The Chevy Silverado has a diesel option in every generation. Those who do more towing and hauling might find that the diesel engine is a better option for them.
The diesel engine can provide more torque and better fuel economy when compared to gasoline.
However, the diesel engine is typically more expensive and might not be available in all trim levels. Therefore, you should do your research before deciding which engine is best for you.
To Wrap Up
Choosing the right Chevy Silverado will depend on your individual needs and what you plan to use the truck for. There are many available options, and each one can be tailored to fit your specific needs.
Be sure to consult with a Chevy dealer to determine which Silverado is right for you. They will be able to answer any of your questions and help you find the best possible deal.
If you already own a Silverado, then there are several things that you can do to improve your fuel economy in your Chevy Silverado. From choosing the right type of oil to installing a chip, plenty of options are available to you.
