What Is The Best Ford Diesel Engine?


When determining your choice among Ford diesel engines, it’s essential to consider factors like towing capacity, power, and reliability.

These elements carry significant weight in your decision, although their importance may vary based on your specific driving requirements and personal preferences.

Let’s explore some of the top Ford diesel engines on the market.


7.3-Litre Power Stroke V8

The 7.3-liter Power Stroke V8 stood as a standout among the most potent diesel engines of its era, with production spanning from 1994 to 2003.

Even today, this V8 engine continues to amaze with its formidable power, peaking at 250 horsepower and boasting nearly 500 lb-ft of torque in its later years.

The V8’s exceptional reliability owes itself to its straightforward design, and numerous owners have confidently surpassed the 300,000-mile mark with their vehicles experiencing minimal issues.

It remains an excellent choice for individuals seeking a robust towing engine, thanks to its impressive 15,000-pound towing capacity.


6.7-Litre Power Stroke V8


Arguably one of the finest Ford diesel engines available, the latest iteration of the 6.7-litre Power Stroke V8 impressively delivers 1,050 lb-ft of torque and 475 horsepower.

With this remarkable power, the V8 can effortlessly tow up to 20,000 pounds, making it an excellent choice for heavy-duty tasks.

Additionally, it is a robust and dependable engine that is unlikely to cause any significant issues.

However, it’s worth noting that the years to potentially avoid are from 2011 to 2014, as these models were known to experience emissions and EGR problems, as well as turbo failures.


3.0-Litre Power Stroke V8


Since the introduction of the V6 engine into Ford’s lineup in 2018, its long-term reliability remains untested.

Nevertheless, if you’re willing to take a chance, you’ll own a truck that blends impressive fuel economy with substantial towing capacity.

Ford suggests that the 3.0-liter Power Stroke can achieve up to 30 miles per gallon (mpg).

The primary drawback of this V6 engine is its price.

Opting for the diesel model typically comes with an additional cost of $4,000 compared to choosing the gasoline version.

This prompts the question of whether the added expense for the diesel version is justified.



What Is The Worst Ford Diesel Engine?


Having gained knowledge about the three finest Ford diesel engines, it’s equally crucial to be informed about the years to steer clear of.

These particular diesel engines experienced reliability issues, resulting in substantial repair expenses for their owners.

Let’s examine them below.


6.0-Litre Power Stroke V8

The 6.0-liter Power Stroke is readily available for purchase online and at local dealerships, but this accessibility is not a positive sign.

Its affordability and widespread availability are attributed to a history plagued with issues.

Common problems associated with this engine encompass the head gasket, oil cooler, turbo, EGR, and injection system.

Unfortunately, these components are susceptible to failure, potentially resulting in substantial repair costs.

Many consumers who have had the misfortune of owning this engine have resorted to using repair kits.

While these kits enhance the engine’s reliability to some extent, it doesn’t make it the best choice.

The 6.0-liter Power Stroke V8 has its merits, including ample power and immediate throttle response.

However, despite any enticing price points, it is advisable to avoid this engine altogether.

For a comprehensive overview of the known issues with the 6.0-liter Power Stroke engine, please refer to the video below.


6.4-Litre Power Stroke V8


While the 6.4-liter engine isn’t plagued with as many issues as the 6.0-liter counterpart, it’s still one to steer clear of due to its poor fuel economy.

The only way to avoid draining your wallet at the gas station is by adding an emissions delete.

Common problems reported by consumers include emissions control failures, injection system issues, and cracked pistons.

These repairs come with a hefty price tag and are often not worth the trouble.

Furthermore, the 6.4-liter engine won’t have the longevity of other diesel engines before requiring significant repairs.

Once you reach the 200,000-mile mark, you should anticipate needing to replace the fuel injectors, fuel pump, and pistons.

The truck does have some positive aspects, such as a highly responsive turbocharger that delivers excellent top-end power.

The 6.4-liter engine is also relatively easy to customize with performance parts, offering high customizability.

While you may come across well-maintained 6.4-liter Power Stroke V8s for sale, our recommendation is to avoid this engine altogether.



Are Ford Diesel Engines Powerful?


A diesel engine generates greater torque compared to a gasoline engine due to its higher compression ratio.

The elevated compression ratio results from the significant pressure and high temperatures within the cylinders.

Additionally, a diesel engine features a larger injector and turbocharger, contributing to an increased power output.

The only downside is their typically higher cost compared to gasoline engines.

While diesel engines may not always excel in terms of raw power, they deliver superior torque, which is advantageous for individuals in need of towing capacity.
