What kind of gas engine is in the 2019 Ford F-550?

The gasoline option in the 2019 Ford F-550 is a 6.2-liter V8 engine (the Boss 6.2). This model also offers a diesel alternative, the 6.7-liter Power Stroke V8 Turbo Diesel, for higher-torque applications.


Engine options for the 2019 Ford F-550


Ford's 2019 F-550 is a commercial-heavy-duty truck that could be configured with either a gasoline V8 or a turbo diesel. The list below highlights the gasoline option first, followed by the diesel option often chosen for heavy-duty workloads.


Gasoline and diesel powertrains available on 2019 F-550 models:



  • Gasoline engine: 6.2-liter V8 gasoline engine (Boss 6.2)

  • Diesel engine: 6.7-liter Power Stroke V8 Turbo Diesel


In practice, fleets decide between the gasoline engine for lower upfront costs and simpler maintenance or the diesel for maximum towing and payload. The availability of each option depends on cab/bed, drivetrain, and configuration.


Gas engine details


The 6.2-liter V8 gasoline engine provides a solid, cost-effective option for light- to medium-duty applications, with sufficient horsepower and torque for many service- and cargo-type tasks. It is paired with the same heavy-duty transmission family used across the Super Duty lineup.


Diesel option details


The 6.7-liter Power Stroke Turbo Diesel delivers substantially higher torque, which is particularly beneficial for heavy towing, steep grades, and demanding payloads. It is a common choice for fleets prioritizing durability and performance over fuel economy.


Summary


The 2019 Ford F-550 offers a gasoline option via the 6.2-liter V8 and a diesel option via the 6.7-liter Power Stroke. Vehicle configuration and intended use determine which powertrain is selected. Review build sheets or consult a dealer for exact specifications in a given truck.

Is the Ford 6.2 L gas engine a good motor?


Yes, the Ford 6.2L gas engine is generally considered a good and reliable engine, but it does have a few common issues that owners should be aware of. It is known for being durable and capable, especially for towing, and many owners report high mileage with minimal repairs. The most frequent problems are related to oil leaks, oil consumption, and, in some cases, faulty valve springs, which can cause serious damage if ignored. 
Pros

  • Reliable and durable: The 6.2L engine is known for its tough design and longevity, with many owners logging hundreds of thousands of miles. 
  • Good for towing: It provides plenty of power for towing and hauling, although a diesel engine will have higher capacity. 
  • Lower maintenance costs than diesel: It's often seen as a more practical and less expensive option than diesel engines, especially if you don't tow 24/7, due to lower maintenance and fuel costs. 
  • Simple operation: It's a straightforward, non-complex engine that doesn't require extensive warm-up and is generally quiet. 

Cons
  • Oil leaks/consumption: Some common issues include engine oil leaks and excessive oil consumption, particularly as the engine ages or accumulates high mileage. 
  • Potential valve spring issues: A less common but serious problem is a faulty valve spring. This can cause a valve to collide with a piston, potentially leading to catastrophic engine failure if not addressed promptly. 
  • Can be loud under load: While generally quiet, its performance under heavy load can be loud, with the engine screaming at high RPMs when pulling heavy loads up grades. 
  • Some electrical issues: Some users report electrical issues with the vehicles the engine is in, though this may not be directly related to the engine itself. 

Overall
The 6.2L is a solid and dependable V8 engine that's a great choice for those who need a capable workhorse without the higher costs associated with diesel engines. Just be prepared for potential oil leaks or consumption over time and, crucially, get any signs of valve spring issues checked out immediately to avoid major damage.



What's the difference between a F-450 and F-550?


The main difference is that the F-450 is available as a pickup truck or a chassis cab, while the F-550 is only offered as a chassis cab. This means the F-450 pickup has a higher maximum towing capacity, while the F-550 is built for higher payload capacities due to its heavier-duty components like its frame and axle ratings, making it better suited for applications like dump trucks, tow trucks, or buses.

Feature F-450 F-550
Configuration Pickup truck or chassis cab Chassis cab only
Payload Capacity Lower for pickup; up to 14,000 lbs for 2025 pickup model Higher for chassis cab; up to 12,750 lbs for 2022 chassis cab model
Towing Capacity Higher for pickup truck; up to 34,300 lbs with a 6.7L diesel engine Lower for chassis cab than F-450 pickup. For 2022, it's 31,600 pounds, but can vary by configuration.
Primary Use General towing and hauling needs Heavier work applications like dump trucks, buses, or tow trucks

Key differences in detail
  • Configuration: The most significant difference is availability. The F-450 offers the versatility of a pickup, while the F-550 is a work-focused chassis cab that serves as a base for commercial upfits like dump bodies. 
  • Payload: The F-550 is built for heavier loads. Its frame, axle, and GVWR are designed for higher payload capacity compared to the F-450 pickup, making it the preferred choice for applications where the truck's body is a significant part of the weight. 
  • Towing: The F-450 pickup typically boasts higher towing numbers, especially when equipped with a gooseneck or fifth-wheel hitch, due to its lighter chassis compared to the F-550's chassis-cab-only setup. 
  • Components: While both trucks share the same engine options, the F-550 has beefier components like its rear axle and frame to handle its higher payload rating. 
  • D-Tuning: F-550 chassis cabs are often "d-tuned" (engine power is limited) to reduce stress on the drivetrain, further prioritizing durability and longevity for heavy work over maximum power. 
  • Suspension: The F-450 pickup and F-450/F-550 chassis cabs have different rear suspension setups. The chassis cab versions use a stiffer, more robust spring pack designed to minimize bouncing under heavy loads, which contributes to their higher payload capacity but results in a less comfortable ride. 



What engine is in a 2019 F-550?


The 2019 Ford F-550 comes equipped with multiple engine types. The 6.8-liter SOHC V10 is paired with a SelectShift-automatic transmission. This transmission delivers high-torque performance, and its strong gears can handle heavy loads. There's also a 6.7-liter Power Stroke engine that's turbo-diesel.



What engine does a Ford F-550 have?


A Ford F-550 typically has either a standard 7.3L V8 gasoline engine or an available 6.7L V8 Power Stroke turbo diesel engine. The gasoline engine produces 335 horsepower and 468 lb-ft of torque, while the diesel option delivers up to 475 horsepower and 1,050 lb-ft of torque, making it the more powerful choice.
