You are not alone in this search, as diesel power remains the king of torque and efficiency for heavy work. In this guide, I will walk you through the current lineup, the history of these engines, and what you need to know before buying one.
Choosing a truck is a significant investment that requires careful thought. I will show you exactly which models currently offer diesel power and how to maintain them for the long haul. Whether you are a weekend DIY mechanic or a full-time hotshot driver, this breakdown covers everything you need to succeed.
We will dive into the technical specs of the 6.7L Power Stroke and look at how Ford’s diesel technology has evolved. By the end of this article, you will have a clear understanding of the Ford diesel landscape. Let’s get under the hood and see what makes these trucks tick.
Current Models: Does Ford Make Diesel Trucks for Every Driver?
The short answer is yes, but the selection has become more specialized in recent years. Currently, Ford focuses its diesel efforts on the Super Duty family. This includes the F-250, F-350, and F-450 models, which are designed for maximum output and durability.
The heart of these trucks is the 6.7L Power Stroke V8 Turbo Diesel. This engine is available in two different tunes: the standard output and the High Output (HO) version. The High Output variant delivers staggering numbers, often leading the class in both horsepower and torque for demanding jobs.
While the F-150 previously offered a 3.0L Power Stroke diesel, Ford discontinued this option in 2021. The shift occurred because their EcoBoost gasoline engines provided similar towing capabilities with lower upfront costs. However, for those who need to move 30,000 pounds or more, the Super Duty diesel remains the only logical choice.
The F-250 and F-350 Super Duty
The F-250 and F-350 are the most common platforms where you will find the 6.7L Power Stroke. These trucks are the bread and butter for contractors and off-road enthusiasts who need a robust frame. They utilize a 10-speed TorqShift automatic transmission that is specifically geared to handle diesel torque.
If you are looking for a truck that can serve as a daily driver and a heavy hauler, the F-250 diesel is a popular middle ground. The F-350 offers higher payload capacities due to its leaf spring configuration. Both models benefit from the massive low-end grunt that only a diesel engine can provide.
The F-450 and Beyond
For the ultimate in towing, the F-450 is a factory-built beast. It comes standard with a wide-track front axle and commercial-grade tires. When people ask, does ford make diesel trucks for professional-grade hauling, the F-450 is the definitive answer.
These trucks are often used in “dually” (dual rear wheel) configurations. This setup provides maximum stability when pulling large trailers in high winds. The F-450 is almost exclusively paired with the diesel engine because gasoline engines struggle to move that much mass efficiently.
The Evolution of the Power Stroke Diesel Engine
Ford’s history with diesel is long and storied, beginning with a partnership with International Harvester (Navistar). The legendary 7.3L Power Stroke is still regarded by many as one of the best diesel engines ever made. It was simple, reliable, and lacked the complex emissions systems found today.
Following the 7.3L, Ford introduced the 6.0L and 6.4L engines. These years were challenging for the brand, as these engines faced reliability issues related to head bolts and emissions hardware. Many DIY mechanics still “bulletproof” these older trucks to make them reliable for modern use.
In 2011, Ford took engine production in-house and debuted the 6.7L Power Stroke. This was a massive turning point for the company. They moved away from Navistar and designed a “reverse-flow” engine that optimized heat management and turbocharger efficiency.
The Move to In-House Production
By designing their own engine, Ford gained total control over the integration between the engine and the chassis. The 6.7L has seen several revisions, each increasing the power and refining the fuel injection system. This engine uses a Bosch CP4.2 high-pressure fuel pump, which requires high-quality fuel to stay healthy.
The current 6.7L engines are much quieter and cleaner than their predecessors. They utilize Selective Catalytic Reduction (SCR) and Diesel Particulate Filters (DPF) to meet strict environmental standards. While these systems add complexity, they allow the truck to produce massive power without the black smoke of the past.
Discontinued Diesel Gems
We cannot discuss Ford diesels without mentioning the 3.0L Power Stroke found in the 2018-2021 F-150. It was a smooth, efficient engine that could achieve over 30 MPG on the highway. While it didn’t have the raw power of the 6.7L, it was perfect for light-duty towing and long commutes.
The Transit van also offered a 3.2L inline-five diesel for several years. This was a workhorse for delivery fleets and van-lifers. Today, these discontinued models are highly sought after on the used market by buyers who want diesel efficiency in a smaller package.
Key Benefits of Driving a Ford Diesel Truck
When you ask, does ford make diesel trucks that outperform gas, the answer lies in the torque curve. A diesel engine reaches its peak torque at very low RPMs. This means you don’t have to floor the accelerator to get a heavy trailer moving from a dead stop.
Another major benefit is engine braking. Ford’s Super Duty trucks feature an integrated exhaust brake. This system uses the turbocharger to create backpressure, helping slow the truck down on steep descents. This saves your service brakes from overheating and provides a much safer towing experience.
Fuel economy under load is also a significant factor. While a gas truck might see its MPG drop into the single digits when towing, a diesel remains relatively efficient. Over long distances, the savings at the pump can help offset the higher initial cost of the diesel engine option.
- Maximum Torque: Essential for moving heavy loads without straining the drivetrain.
- Longevity: Diesel engines are built with heavier duty components than gas engines.
- Resale Value: Ford diesel trucks typically hold their value much better than gas versions.
- Range: Better fuel economy allows for longer distances between fill-ups.
Maintenance Essentials for Your Diesel Engine
Owning a diesel truck requires a different maintenance mindset than a standard car. You cannot skip service intervals if you want the engine to last 300,000 miles. The most critical aspect of diesel maintenance is fuel filtration and water separation.
Diesel fuel can attract moisture, which is deadly to high-pressure injectors. Ford trucks have two fuel filters that must be changed regularly. One is located near the fuel tank and acts as a water separator, while the other is on top of the engine to catch fine particles.
You also need to stay on top of your Diesel Exhaust Fluid (DEF) levels. If the truck runs out of DEF, it will enter a “limp mode,” significantly reducing your speed. Always keep a jug of high-quality DEF in your garage or tool box to avoid being stranded on the side of the road.
- Oil Changes: Use high-quality synthetic oil designed for diesel compression.
- Fuel Filters: Change both filters every 15,000 to 22,500 miles, or sooner in dusty conditions.
- Coolant Checks: Modern diesels have complex cooling systems that need proper pH levels.
- Battery Health: Diesels require massive cranking amps; always check your dual battery setup.
The Importance of Motorcraft Parts
As an experienced technician, I always recommend using Motorcraft filters and fluids. Ford engineers design these parts specifically for the tolerances of the Power Stroke engine. Using cheap, off-brand oil filters can lead to oil starvation or poor filtration, which costs more in the long run.
If you are a DIYer, investing in a good OBD-II scanner is essential. This allows you to monitor the “soot load” in your DPF and see when the truck is performing a regeneration cycle. Understanding these cycles helps you avoid shutting the truck off mid-process, which can clog the filter over time.
Does Ford Make Diesel Trucks with Common Reliability Issues?
While modern Ford diesels are incredibly robust, they are not without potential pitfalls. The emissions system is the most common source of headaches for owners. Components like the EGR valve and the DPF can become clogged if the truck is only driven for short trips in the city.
Diesel engines need to get hot to stay clean. If you use your Super Duty only for grocery runs, the soot will build up quickly. Taking the truck on a long highway drive once a week allows the exhaust system to reach the temperatures needed to burn off that soot naturally.
Another area to watch is the CP4 fuel pump. This pump relies on the lubricity of diesel fuel to stay cool. In the United States, our ultra-low sulfur diesel (ULSD) can sometimes be “dry.” Many owners use a fuel additive to increase lubricity and protect the expensive injection system from premature wear.
Turbocharger Care
The turbocharger is a precision component that spins at thousands of RPMs. To ensure its life, never shut your engine off immediately after a hard pull or a highway run. Let the engine idle for 2-3 minutes to allow oil to circulate and cool the turbo bearings.
If you notice a sudden loss of power or a loud whistling noise, you may have a “boost leak.” This is often just a rubber boot that has slipped off a pipe. Checking your clamps and hoses regularly is a simple way to prevent a tow truck bill.
Cold Weather Starting
If you live in a cold climate, you must understand how glow plugs work. These small heating elements warm the combustion chamber to help the diesel ignite. Always wait for the “wait to start” light to turn off before cranking the engine in freezing temperatures.
Using a block heater is also a pro tip for winter survival. Plugging your truck in overnight keeps the oil thin and the block warm. This reduces wear on the engine during those first few critical seconds of operation on a sub-zero morning.
Choosing the Right Truck for Your Needs
Before you head to the dealership, ask yourself what you truly need. If you are towing a trailer that weighs under 10,000 pounds, a gasoline F-150 might be more cost-effective. However, if you are an off-roader building a heavy camper rig, the diesel is worth every penny.
Consider the payload. A diesel engine is much heavier than a gas engine. This weight eats into your total payload capacity. On an F-250, the heavy diesel engine can sometimes leave you with less payload than a gas-powered F-150. If payload is your priority, look at the F-350 with the diesel option.
Finally, think about the long-term costs. Diesel fuel is often more expensive than gasoline, and oil changes cost more due to the large volume of oil required. You must balance these operating costs against the superior performance and high resale value that the truck provides.
