What is the gas mileage on a 2013 Chevy Avalanche?
The 2013 Chevy Avalanche with the 5.3L V8 typically gets about 16 mpg in city driving and 22 mpg on the highway in 2-wheel-drive versions, and around 15 mpg city and 21 mpg highway in 4-wheel-drive versions. Real-world results vary depending on load, terrain, and driving habits.
EPA estimates by drivetrain
EPA fuel-economy estimates provide a baseline for what to expect, with variations based on drivetrain configuration. The figures below reflect the standard powertrain shared with the Silverado 1500 family.
- 2WD, 5.3L V8: 16 mpg city / 22 mpg highway (combined around 18 mpg).
- 4WD, 5.3L V8: 15 mpg city / 21 mpg highway (combined around 17 mpg).
These official numbers help with trip planning and comparing to newer pickups; actual mileage will vary with usage and maintenance.
What drives mileage on the 2013 Avalanche?
Fuel economy on the Avalanche is influenced by drivetrain, payload, and driving style. The main variables are:
- Payload and towing: Heavier loads reduce mpg, especially when towing.
- Driving conditions: Stop-and-go city driving lowers efficiency compared with steady highway cruising.
- Tire setup and aerodynamics: Larger tires, roof racks, and other accessories increase drag and reduce mpg.
- Maintenance: Regular servicing, clean air filters, proper tire inflation, and quality fluids help efficiency.
- Vehicle age and condition: Wear on engine and drivetrain components can affect fuel economy over time.
In practice, mileage will be highest on well-maintained 2WD models and may dip with heavy loads or aggressive driving.
Tips to maximize fuel economy in a 2013 Avalanche
Owners can take several practical steps to improve mpg, even on an older full-size pickup:
- Keep tires inflated to the recommended pressure; underinflation hurts efficiency.
- Remove unnecessary weight and aerodynamic drag when possible (e.g., roof racks).
- Drive smoothly: gradual acceleration and steady speeds reduce fuel use.
- Plan trips to minimize idling and combine errands to reduce cold starts.
- Follow a regular maintenance schedule for the engine, transmission, air filters, and fluids.
Adopting these practices can yield noticeable gains in real-world fuel economy for the 2013 Avalanche.
Summary
The 2013 Chevy Avalanche delivers EPA-estimated mileage in the mid-teens to low-20s range, with 2WD outperforming 4WD. While these numbers offer a useful benchmark, actual fuel economy depends on driving style, load, and upkeep. With mindful driving and regular maintenance, owners can optimize mpg on this capable full-size pickup.
What is the most reliable year of the Chevy Avalanche?
Most Reliable Years For The Chevy Avalanche
- 2006 Chevy Avalanche.
- 2009 Chevy Avalanche.
- 2011 Chevy Avalanche.
- 2012 Chevy Avalanche.
- 2013 Chevy Avalanche.
What year is the Avalanche to stay away from?
Years to be cautious with include the 2003 (transmission problems), 2005 (3-4 clutch failure), and models with the Active Fuel Management (AFM) system, which was introduced around 2007. The 2011 and 2013 models also have notable recall issues.
This video discusses common problems with the Chevrolet Avalanche, including issues with the AFM system: 49sCCV TVYouTube · Apr 2, 2019
Years with significant issues
- 2003: Has a history of significant transmission problems, which can range from shifting issues to complete failure.
- 2005: Particularly prone to 3-4 clutch failure, which can leave the transmission stuck in second gear.
- 2011: Subject to recalls for rear axle cross pins that were improperly heat-treated, potentially leading to fracture and displacement.
- 2013: Has recalls for issues with the park lock cable or steering column lock actuator gear.
Other considerations
- 2007-2013 (Second Generation): This generation introduced the AFM system, which can lead to engine misfires, rough idling, and eventual engine damage if not properly maintained.
- Pre-2007: The engine in the first generation (2002-2006) is generally considered more durable, though the transmission may require more maintenance, and the plastic body cladding can fade and degrade over time.
- Rust: Regardless of the year, be cautious with models from rust-prone areas. The Avalanche's bed is also not watertight and tends to leak.
How to choose
- If engine longevity is a priority, consider the 2002-2006 models without AFM, but be prepared for potential transmission work.
- If you prefer a more modern vehicle, look for a model year that avoids the specific problems listed above. Even though the 2011 and 2013 models have specific recalls, they are generally considered reliable after the issues are addressed.
