1. Overview of the Engines
6.2L V8 Gasoline Engine
The 6.2L V8, also known as the Boss engine, is a naturally aspirated gas engine that’s been a staple in the Ford Super Duty lineup since 2011. It was designed as a workhorse for those who don’t require diesel power but still need a capable and durable truck.
- Power Output: 385 horsepower and 430 lb-ft of torque.
- Configuration: Overhead valve (OHV) with a cast iron block and aluminum heads.
- Fuel Type: Regular unleaded gasoline.
6.7L Power Stroke V8 Turbo Diesel Engine
The 6.7L Power Stroke is Ford’s flagship diesel engine for heavy-duty trucks. Introduced in 2011, it’s been continually refined to improve power, efficiency, and durability.
- Power Output: Varies by model year but ranges from 400 to 500 horsepower and 800 to over 1,200 lb-ft of torque.
- Configuration: Overhead valve (OHV) with a compacted graphite iron (CGI) block and aluminum heads.
- Fuel Type: Diesel.
2. Performance and Power Delivery
6.2L Gas
The 6.2L engine delivers consistent and smooth power, making it ideal for daily driving and moderate workloads. Its naturally aspirated design ensures linear throttle response and simplicity. However, it lacks the torque required for extreme towing or hauling.
- Best Use Cases: Light to moderate towing, construction work, and personal use.
- Acceleration: Responsive in city driving but can feel underpowered under heavy loads.
6.7L Diesel
The 6.7L Power Stroke dominates in terms of torque, making it the go-to choice for those who need to tow heavy trailers or carry significant payloads. The turbocharger ensures high power at low RPMs, essential for pulling loads uphill or accelerating while towing.
- Best Use Cases: Long-distance towing, RV hauling, and heavy-duty commercial applications.
- Acceleration: Excellent under load, with the diesel torque kicking in early.
3. Towing and Payload Capacity
Ford Super Duty trucks with the 6.7L diesel engine have significantly higher towing and payload capacities compared to their 6.2L gas counterparts. This difference stems from the diesel engine’s superior torque and efficiency under load.
- 6.2L Towing: Maximum towing capacity of around 15,000 pounds (depending on the truck configuration).
- 6.7L Towing: Can tow up to 37,000 pounds when equipped with a gooseneck hitch (varies by model year and configuration).
If your work involves frequent heavy towing, the 6.7L is the clear winner. For occasional towing or lighter loads, the 6.2L offers enough capability without the added expense of diesel.
4. Fuel Efficiency
Fuel efficiency is where the choice gets more nuanced:
- 6.2L Gas: Gasoline engines generally consume more fuel under load. Expect around 12-15 mpg in light-duty conditions and significantly less when towing or hauling heavy loads.
- 6.7L Diesel: Diesel engines are more fuel-efficient, especially under load. The 6.7L can achieve 15-20 mpg in light-duty use and maintain decent efficiency even while towing.
However, diesel fuel typically costs more than gasoline, and the total cost per mile may balance out, depending on fuel prices and usage.
5. Maintenance and Ownership Costs
6.2L Gas
- Maintenance Costs: Lower than diesel engines due to simpler design. Routine tasks like oil changes and spark plug replacements are more affordable.
- Longevity: Gas engines generally don’t last as long as diesels under heavy use, but they can still provide 200,000+ miles with proper care.
- Repairs: Parts are more readily available and cheaper.
6.7L Diesel
- Maintenance Costs: Higher due to the complexity of diesel systems. Components like the turbocharger, fuel injectors, and DEF (Diesel Exhaust Fluid) system require regular attention.
- Longevity: Diesels are built to last, often exceeding 300,000 miles when maintained correctly.
- Repairs: Repairs can be costly, especially for the turbocharger or emissions systems.
6. Purchase Price and Resale Value
- 6.2L Gas: Trucks equipped with the 6.2L engine are more affordable upfront, often saving buyers $8,000–$10,000 compared to diesel models. However, resale value is generally lower.
- 6.7L Diesel: While the initial cost is higher, the 6.7L Power Stroke holds its value better, making it a better investment for long-term ownership.
7. Environmental Impact
The environmental impact of each engine depends on usage:
- 6.2L Gas: Produces more CO2 emissions per gallon of fuel burned, but modern gas engines meet strict emissions standards.
- 6.7L Diesel: Diesel engines emit less CO2 but can produce higher levels of nitrogen oxides (NOx) and particulates. However, DEF and advanced emissions systems mitigate these effects.
8. Choosing the Right Engine for Your Needs
When deciding between the Ford 6.2L and 6.7L engines, consider these factors:
Choose the 6.2L Gas If:
- You need a truck for daily driving with occasional towing.
- You prefer lower upfront and maintenance costs.
- You don’t need extreme towing or hauling capabilities.
Choose the 6.7L Diesel If:
- You regularly tow or haul heavy loads.
- You prioritize long-term durability and higher resale value.
- You want the best fuel efficiency under load.
9. Real-World Feedback
Drivers of the 6.2L often praise its reliability and affordability, especially for personal or light commercial use. Meanwhile, 6.7L owners highlight its unmatched towing capability and power delivery, though some note the higher maintenance costs.
Conclusion
Both the 6.2L gas and 6.7L diesel engines are excellent choices within the Ford Super Duty lineup, but they cater to different audiences.
The 6.2L is a cost-effective, versatile option for lighter tasks, while the 6.7L shines in heavy-duty applications where power and durability are paramount.
Understanding your specific needs and how you’ll use your truck is key to making the right choice.
Whether you’re hauling an RV across the country or running errands around town, Ford’s engine lineup ensures you’ll find a truck that’s up to the task.
