Best MPG Trucks – Fuel Efficiency & Performance in One Package

A decade ago, we didn’t pay attention to fuel economy and bills at the gas station. Now, when gas price is changing daily (funny, they call it price correction), we need to put fuel economy on our priority list. Unfortunately, as a truck driver, you are familiar with this very well. You need to spend a lot of money to fill in 25 gallons fuel tank of an average full-sized truck.

Hopefully, car makers help us a lot. With new technologies and smart solutions used with engine and transmission, it’s possible to have fuel efficient truck that offers high performance as a daily commuter and working horse.

So, fuel economy and capability can go hand in hand.

Lines below talk about most fuel-efficient trucks, but before we jump to models, MPG data, trim level, and prices let us quickly introduce the most influential factors when it comes to fuel efficiency.

Things That Kill Fuel Efficiency

To be clear at the very beginning. Fuel Economy is a measure of how far vehicle can travel with one gallon of fuel. It’s measured in miles per gallon (MPG). Opposite to fuel economy is Fuel Consumption that represents the amount of fuel consumed in gallons per 100 miles.

Here are the most common things that influence truck fuel consumption:

1. The old truck that gave its best – If your truck is produced in late 80’ don’t expect to achieve fuel economy declared by the manufacturer. Old engine with half a million miles or more on the odometer usually means trouble with reliability.

2. Truck size – small and medium-sized trucks usually have better fuel economy the heavy-duty counterparts. Compare Honda Ridgeline and Ford Super Duty. Lighter trucks use less fuel.

3. Engine and transmission – Powertrain suffered significant technological changes over the years. Use of new, light-weight materials for engine components and chassis decreased vehicle weight. Less weight means better fuel economy. To gain better fuel efficiency and power output, Ford developed new gearbox for new full-sized trucks that has 10 automatic speeds.

4. Fuel type – diesel trucks have better fuel economy, period. See the first four spots on our list, and you’ll get it. Read this handful guide to learn differences between diesel and gas trucks, and decide do you need to buy a diesel if you don’t haul and tow big things.

5. Driving habits – driving at inconsistent speeds, rapid acceleration, and speeding decrease truck fuel efficiency. Drive smarter and smoother!

6. Business or pleasure? If you use the truck as an everyday commuter or lifestyle vehicle you probably can achieve manufacturer declared MPG numbers. In cases, you tow a trailer or haul heavy things don’t be surprised to see much worse fuel efficiency.

7. City or Highway? Constant accelerations and braking in jammed city streets are a real terror for your fuel economy. Constant speed on the highway is much pleasant and fuel friendly environment for any vehicle.

8. Location & weather condition – if you live in sunny California, fuel consumption, due to the optimal temperature, is going to be better compared to those who drive the same truck in cold Duluth, Minnesota.

There are undoubtedly even more factors we can add here, like truck upfit, tire profile, maintenance, and other.
Don’t forget that numbers you see on the stickers of the truck’s windows reflect the results of a test done by the manufacturer in strictly defined conditions in the laboratory. That are just estimations, and usually, results vary from those achieved in everyday traffic. However, if you drive with fuel efficiency in mind, you can achieve manufacturer results.

5 Most Fuel Efficient Trucks

How we rated trucks with the good gas mileage? We rated according to EPA fuel economy, not MPG estimates from vehicle owners. Under the image you’ll see most crucial information related to truck fuel efficiency; engine displacement, fuel type, transmission, city/highway and combined fuel economy, tank capacity, and cost to fill the tank according to average gas price in the US.
