The Chevy Avalanche, a versatile full-size pickup truck, combines the comfort of an SUV with the utility of a truck.
As of the latest model produced (2013) the Chevy Avalanche has a gas tank size of 31 gallons. This capacity allows for extended driving ranges, making it an ideal choice for long trips and heavy-duty hauling.
Even though the Avalanche hasn’t been produced in over a decade, there is still a thriving market for used trucks. So if you find yourself with a deal and need to know some gas tank and mileage stats, you’re in the right place!
Gas Tank Capacity by Model Year
2010-2013: All models during these years feature a 31-gallon fuel tank, catering to the vehicle’s V8 engine and providing an admirable balance between power and fuel efficiency.
Fuel Tank Size by Year
Let’s break down the fuel tank sizes by year and model variations:
| Year | Model | Tank Capacity (gallons) |
|---|---|---|
| 2013 | Avalanche | 31 |
| 2012 | Avalanche | 31 |
| 2011 | Avalanche | 31 |
| 2010 | Avalanche | 31 |
Fuel Efficiency and Range
Impact on Driving and Planning
The 31-gallon tank allows for significant driving ranges. This makes the Avalanche a solid choice for those who prioritize less frequent stops at the gas station.
Given the average fuel efficiency of around 15 miles per gallon (city) and up to 21 miles per gallon (highway,) owners can expect a range of 465 to 651 miles on a full tank, depending on driving conditions.
This capacity influences trip planning, budgeting for fuel, and vehicle maintenance, emphasizing the importance of understanding your vehicle’s specific fuel consumption patterns.

How Towing Impacts Gas Mileage and Fuel Efficiency
Whether it’s hauling a boat, transporting a trailer, or carrying heavy loads, the Avalanche is up to the task.
However, towing affects gas mileage and fuel efficiency, with the impact varying depending on the weight of the load—categorized here as light, medium, and heavy.
Light Loads: Minimal Impact on Efficiency
Towing light loads, such as small trailers or jet skis, has a minimal impact on the Chevy Avalanche’s fuel efficiency. The vehicle’s powerful engine and aerodynamic design allow it to handle such tasks without significantly increasing fuel consumption.
Drivers might notice a slight decrease in miles per gallon (MPG), but this is usually negligible. The vehicle’s performance remains efficient, thanks to the Avalanche’s ability to distribute power effectively, ensuring that the engine does not overwork.
Medium Loads: Noticeable Efficiency Reduction
When the Avalanche is used to tow medium loads, such as larger boats or mid-sized trailers, the impact on fuel efficiency becomes more noticeable.
The additional weight requires the engine to work harder, especially on inclines or at highway speeds, leading to increased fuel consumption.
Drivers can expect a moderate decrease in MPG during such towing tasks.
However, the Avalanche’s design and engine calibration are optimized to handle this level of demand, ensuring that while fuel efficiency is affected, the vehicle can still maintain a balance between power and economy.
Heavy Loads: Significant Efficiency Challenge
Towing heavy loads, such as large trailers, campers, or heavily loaded utility trailers, presents the most significant challenge to the Chevy Avalanche’s fuel efficiency.
The strain on the engine is at its highest in these scenarios, leading to a substantial decrease in MPG. The vehicle’s fuel consumption can increase dramatically, depending on the weight of the load, terrain, and driving conditions.
It’s during these heavy towing tasks that the Avalanche’s fuel efficiency is most impacted, emphasizing the trade-off between towing capacity and fuel economy.
Drivers planning to tow heavy loads should anticipate more frequent stops for fuel, as the vehicle works to balance the demands of heavy towing with engine performance and efficiency.
Maximizing Efficiency While Towing
To optimize fuel efficiency while towing with the Chevy Avalanche, drivers can adopt several strategies. These include:
- Maintaining Steady Speeds
- Avoiding Sudden Accelerations
- Vehicle and Trailer Maintenance
- Loads are Aerodynamically Configured.
- Proper Tire Pressure
- Regular Engine Check-Ups
