The three best-selling vehicles in America are pickup trucks. The Ford F-150, Ram 1500, and Chevrolet Silverado collectively account for more than 1.5 million annual sales, and a significant portion of buyers never seriously compare what they will spend at the pump before signing paperwork. This guide fixes that. We compare real annual and five-year fuel costs across the most popular powertrain configurations of each truck so you can make a financially complete decision.
Use the GasBudgeter Gas Budget Calculator to run a custom fuel cost projection for any specific engine and trim combination using your own mileage and local prices. For the broader vehicle class perspective, see our annual fuel cost by vehicle class guide.
The Methodology
All comparisons use 15,000 miles per year, a city and highway driving split of 55 to 45 percent, and a gas price of $3.60 per gallon. Annual fuel cost figures are derived from EPA combined MPG ratings for each specific powertrain. Five-year costs assume the same price per gallon throughout, which is conservative since prices historically trend upward. We cover the three most popular engine choices for each truck separately because powertrain choice is often the biggest fuel economy variable within a model family.
Ford F-150: Fuel Costs by Engine
F-150 2.7L EcoBoost V6: $2,047 Per Year
The 2.7-liter turbocharged EcoBoost is the sweet spot for F-150 fuel economy in a gasoline-only configuration. At approximately 20 MPG combined, it costs around $2,047 per year in fuel at our standard assumptions. This is the balance point between performance and efficiency in the F-150 lineup and one of the most popular engine choices.
F-150 3.5L EcoBoost V6: $2,250 Per Year
The 3.5-liter EcoBoost is Ford's towing-focused choice and the most popular engine in the lineup. At approximately 18 MPG combined, it costs about $2,250 per year. The difference versus the 2.7-liter is roughly $200 per year. Over five years that is $1,000 more in fuel for buyers who rarely use the additional towing capacity the larger engine provides.
F-150 5.0L V8: $2,419 Per Year
The naturally aspirated 5.0-liter V8 at approximately 17 MPG combined costs about $2,419 per year. That is $372 more per year than the 2.7-liter EcoBoost. Over five years the gap reaches $1,860.
F-150 PowerBoost Hybrid: $1,632 Per Year
The PowerBoost hybrid is the most fuel efficient F-150 available. At approximately 24 MPG combined, it costs about $1,632 per year, saving roughly $415 per year versus the 2.7-liter EcoBoost. Over five years the saving reaches $2,075, which largely offsets the hybrid price premium. The PowerBoost also offers 7.2 kW of onboard power generation, useful for work truck applications.
Ram 1500: Fuel Costs by Engine
Ram 1500 3.6L Pentastar V6 with eTorque: $2,047 Per Year
The V6 with eTorque mild hybrid achieves approximately 19 MPG combined, matching the F-150 2.7-liter at about $2,047 per year. Ram's eTorque system adds a small electric motor assist that improves fuel economy at low speeds and during acceleration compared to the non-eTorque version, which runs closer to 17 MPG combined.
Ram 1500 5.7L HEMI V8 with eTorque: $2,250 Per Year
The 5.7-liter HEMI with eTorque mild hybrid achieves approximately 18 MPG combined, slightly better than the F-150 V8 due to cylinder deactivation and mild hybrid assist. Annual fuel cost is about $2,250. Without eTorque the HEMI drops to approximately 16 MPG combined, pushing annual cost to $2,531.
Ram 1500 3.0L EcoDiesel V6: Approximately $2,077 Per Year
The EcoDiesel at approximately 26 MPG combined highway-focused efficiency costs approximately $2,077 at diesel pricing around $4.00 per gallon. For highway-heavy drivers who cover significant annual mileage, diesel efficiency at highway speeds often outpaces mild hybrid gasoline alternatives. This is the choice of drivers who prioritize long-distance highway fuel economy.
Chevrolet Silverado 1500: Fuel Costs by Engine
Silverado 1500 2.7L Turbo: $2,016 Per Year
Chevy's inline-four turbocharged 2.7-liter engine at approximately 20 MPG combined has an annual fuel cost of approximately $2,016. This is the most fuel efficient gasoline engine available in the Silverado and positions it competitively against the F-150 2.7-liter EcoBoost.
Silverado 1500 5.3L V8: $2,250 Per Year
The 5.3-liter V8 at approximately 18 MPG combined with cylinder deactivation technology costs approximately $2,250 per year, similar to the Ram HEMI V8 eTorque. The V8 remains the most popular engine in the Silverado lineup despite the improved efficiency options available.
Silverado 1500 6.2L V8: $2,531 Per Year
The 6.2-liter V8 at approximately 16 MPG combined costs approximately $2,531 per year. Buyers choosing the 6.2 for its towing capacity should factor this fuel cost premium into their total ownership calculation.
The Five-Year Fuel Cost Comparison
Here is the complete five-year picture at $3.60 per gallon and 15,000 miles per year:
F-150 PowerBoost Hybrid: $8,160 over five years
F-150 2.7L EcoBoost and Ram 1500 V6 eTorque: approximately $10,235 each
Silverado 2.7L Turbo: approximately $10,080
Ram HEMI V8 eTorque and Silverado 5.3L: approximately $11,250 each
F-150 5.0L V8: approximately $12,095
Ram 5.7L HEMI without eTorque and Silverado 6.2L: approximately $12,655
Pro Tip
Always use the GasBudgeter Calculator with the specific engine and trim combination you are considering, your actual monthly mileage, and your local fuel price. National averages shift the numbers, but your personal driving pattern is what determines your personal cost.
The difference between the most and least fuel efficient gasoline powertrain options across these three trucks is approximately $2,420 per year, or $12,100 over five years. That is a figure large enough to meaningfully affect which configuration is the better overall financial choice.
Frequently Asked Questions
Which full-size truck has the best fuel economy in 2026?
The Ford F-150 PowerBoost Hybrid leads all full-size gasoline pickup trucks at approximately 24 MPG combined. Among non-hybrid gasoline options, the Silverado 2.7L Turbo and F-150 2.7L EcoBoost both achieve approximately 19 to 20 MPG combined and are the most fuel efficient conventional gasoline engines in this segment.
Is the F-150 Hybrid worth the extra cost for fuel savings?
At $3.60 per gallon and 15,000 miles per year, the F-150 PowerBoost saves approximately $415 per year over the 2.7L EcoBoost. Over five years that is about $2,075 in fuel savings. If the hybrid premium falls within $3,000 to $4,000 above the EcoBoost version, the fuel savings make a compelling financial case for buyers who plan to own the truck for five or more years.
Does towing reduce pickup truck fuel economy significantly?
Yes, substantially. A truck rated at 20 MPG combined may see fuel economy fall to 10 to 14 MPG when towing near its maximum capacity due to the aerodynamic drag of the trailer and the additional load on the drivetrain. Heavy towers should budget fuel costs based on actual towing efficiency rather than the EPA combined rating for general driving.
How does diesel fuel economy compare to gasoline for pickup trucks?
Diesel engines in trucks typically achieve 20 to 30 percent better fuel economy per gallon than gasoline equivalents. However, diesel fuel costs more per gallon than regular gasoline, which offsets some of the efficiency advantage. The diesel advantage is most pronounced in highway-heavy driving patterns where diesel engines achieve their best efficiency.
Which truck engine should I choose if fuel economy is my top priority?
The F-150 PowerBoost Hybrid is the clear winner for maximum fuel efficiency in a full-capability full-size truck. If hybrid is not in your budget, any of the V6 turbocharged options from any of the three manufacturers will outperform the V8 options meaningfully in everyday driving.
How accurate are EPA fuel economy ratings for pickup trucks?
EPA ratings for pickup trucks typically reflect real-world efficiency reasonably well for highway driving but tend to overestimate city efficiency because truck stop-and-go behavior in real traffic can be less efficient than the EPA test cycle assumes. Many truck owners report 1 to 3 MPG below the EPA combined rating in typical mixed driving.
Does truck bed size or cab configuration affect fuel economy?
Extended or crew cab configurations add weight compared to regular cab versions and slightly change aerodynamics. The fuel economy penalty is typically 1 to 2 MPG. Cab and bed choices should be driven by your actual utility needs, as the differences in fuel economy are small enough not to be the deciding factor.
How much do truck gas costs change with different payload amounts?
For every 1,000 pounds of payload in the truck bed, fuel economy typically falls by 2 to 4 MPG depending on engine size and vehicle weight. A full half-ton payload in a truck rated at 20 MPG can reduce effective economy to 16 to 18 MPG during the loaded trip. Budget for loaded operating costs separately from empty commute costs if you regularly haul heavy loads.
Is it worth buying a more efficient truck engine to save on fuel?
The answer depends on your annual mileage and ownership period. At 15,000 miles per year, the difference between the 2.7L EcoBoost and the 5.0L V8 in the F-150 is about $372 per year. Over five years that is $1,860. If the V8 adds less than $1,860 to the purchase price over the EcoBoost, the V8 costs less over five years in total fuel-adjusted cost.
How does truck fuel economy compare to a comparable SUV?
Full-size pickup trucks typically average 1 to 5 MPG worse than comparable full-size SUVs built on the same platform, primarily because truck aerodynamics are worse than enclosed SUV bodies. Compact and mid-size SUVs built on car-based platforms outperform pickup trucks by 6 to 12 MPG in most configurations.
Can I reduce my truck fuel costs without changing vehicles?
Yes. Maintaining correct tire pressure, keeping the truck bed clear of unnecessary weight, avoiding roof-mounted accessories when not in use, using cruise control on highways, and reducing speed from 80 mph to 65 mph are all high-impact behavioral changes for truck drivers. See our guide to hypermiling techniques for the full range of strategies that apply to any vehicle including trucks.
