Finding a used truck that offers excellent gas mileage might seem like a contradiction in terms. Trucks, by their nature, are typically less fuel-efficient than cars. However, several factors influence a truck's MPG, and with careful research, you can find a used truck that won't break the bank at the pump. This guide explores the best used trucks for fuel efficiency, offering insights to help you make an informed decision.
What Factors Affect a Truck's MPG?
Before diving into specific models, understanding the factors influencing a truck's fuel economy is crucial. These factors play a significant role in determining the real-world MPG you can expect:
- Engine Size and Type: Smaller displacement engines (e.g., 4-cylinder or smaller V6) generally deliver better fuel economy than larger V8 engines. Diesel engines, while powerful, can sometimes offer better MPG than comparable gasoline engines, especially when towing or hauling heavy loads. However, the initial cost of diesel fuel is usually higher.
- Transmission: Modern automatic transmissions with more gears often contribute to better fuel efficiency than older automatics or manual transmissions.
- Drivetrain: 4x2 (rear-wheel drive) trucks are generally more fuel-efficient than 4x4 (four-wheel drive) trucks because of the added weight and mechanical complexity of the four-wheel-drive system.
- Vehicle Weight and Aerodynamics: Lighter trucks and those with more aerodynamic designs tend to have better MPG. Added accessories, such as lift kits or large aftermarket wheels and tires, can negatively impact fuel economy.
- Driving Habits: Aggressive driving, excessive idling, and hauling heavy loads significantly reduce fuel efficiency.
What are the Best Used Trucks for MPG?
Several used truck models consistently rank higher in fuel economy than their counterparts. Remember that actual MPG can vary based on the factors listed above and the truck's condition.
-
Compact and Mid-Size Trucks: These trucks generally offer the best fuel economy. Look for used models of the following:
- Honda Ridgeline: Known for its car-like handling and surprisingly good fuel economy.
- Toyota Tacoma: While not the most fuel-efficient, certain years and trims of the Tacoma offer relatively good MPG for a mid-size truck.
- Chevrolet Colorado/GMC Canyon: These trucks, especially those with the smaller 4-cylinder engines, can achieve decent MPG.
- Nissan Frontier: Similar to the Tacoma, certain years and trims of the Frontier are more fuel-efficient than others.
-
Full-Size Trucks (with caveats): While full-size trucks typically have lower MPG, some models with smaller engines or fuel-saving technologies can still be relatively efficient. Look for used models with:
- V6 engines: These offer a better balance of power and fuel economy compared to V8 engines.
- Fuel-saving technologies: Features like cylinder deactivation (which shuts off some cylinders under light loads) can improve fuel economy.
Which Used Truck MPG Should I Expect?
The MPG you can expect from a used truck varies greatly. You'll likely see figures ranging from:
- Compact/Mid-Size Trucks: 18-25 MPG (combined city/highway)
- Full-Size Trucks: 15-22 MPG (combined city/highway)
Keep in mind these are estimates, and real-world MPG will depend on your driving habits and the truck's condition. Always check the EPA fuel economy estimates for the specific year and model you're considering.
How Can I Improve My Used Truck's MPG?
Even after purchasing a fuel-efficient used truck, there are steps you can take to maximize its fuel economy:
- Maintain proper tire pressure: Under-inflated tires increase rolling resistance and reduce MPG.
- Regular maintenance: Ensure your truck receives regular maintenance, including oil changes and tune-ups.
- Drive efficiently: Avoid aggressive acceleration and braking. Maintain a steady speed, especially on highways.
- Reduce weight: Remove any unnecessary weight from your truck bed.
What are the Best Years for Fuel-Efficient Used Trucks?
Pinpointing specific "best years" is challenging as fuel economy improvements are incremental and vary by model. However, newer used trucks (generally from the last 10 years) often incorporate more fuel-efficient technologies than older models. Always research the specific model year you are interested in to find its EPA fuel economy rating.
Are Diesel Trucks More Fuel Efficient Than Gas Trucks?
Diesel trucks often offer better fuel economy when hauling heavy loads or towing. However, under normal driving conditions, the difference might be minimal or even reversed, especially considering the higher cost of diesel fuel. The best choice depends on your specific needs and driving style.
By carefully considering these factors and researching specific used truck models, you can find a reliable and fuel-efficient vehicle that suits your needs and budget. Remember to always test drive potential purchases and have them inspected by a mechanic before making a final decision.
