Ford introduced the 3.0-liter Power Stroke in the 2018 F-150 as a fuel-economy option in the lineup — get the engine if you want diesel torque and highway efficiency without stepping up to a heavy-duty truck. It returned up to 30 mpg on the highway and up to 440 pound-feet of torque, numbers that make a really strong case for those who towed regularly and kept an eye on fuel costs.
For a brief moment, it seemed as if Ford had quietly built one of the most intelligent F-150s ever. However, it only lasted four model years. Ford pulled the plug after 2021, and the 2022 F-150 lineup moved forward without any farewell press release. No successor, no upgrade path, no explanation beyond a corporate memo pointing to a change in customer preferences.
The reasons behind that decision are rapidly emerging, and none of them are attractive. A new hybrid power train came along and surpassed it in power, torque and towing capacity all at once. Buyers also continued to choose gasoline engines over Power Stroke, causing diesel sales to decline year over year.
And underneath all that, the engine had reliability issues that made ownership more high-maintenance than for the average F-150 buyer. These days, some believe the 3.0 Power Stroke is underrated, but others believe its demise was completely logical.
Why was the 3.0L Power Stroke dismissed?
When the closure was confirmed in July 2021, a representative for Ford released a statement motortrend The position was summarized clearly: “Our customers order our EcoBoost V6 gasoline engine in large volumes, which is why we are removing the diesel from our lineup. For customers who require maximum towing torque, we now offer the F-150 PowerBoost as the ideal combination of capacity, power and fuel efficiency, which was not available at the time of the Power Stroke’s introduction.”
Translation: Buyers didn’t want it, and a better option came along. The numbers support this. The PowerBoost Hybrid delivers 430 horsepower and 570 lb-ft of torque, tows 12,700 pounds and carries a maximum payload of 2,120 pounds. The 3.0-liter Power Stroke manages 250 hp, 440 lb-ft, 12,100 pounds of towing and a payload of 1,840 pounds. The Power Stroke was rated at 22 mpg city, 27 highway. The PowerBoost Hybrid came in at 24/24.
However, diesel fuel prices have been higher than regular-grade gasoline prices for nearly 20 years. The engine that Ford marketed as the fuel-saver of the F-150 lineup was burning fuel that cost more, while providing slightly better mpg ratings on the highway and worse ratings in the city. For most buyers, the math didn’t work out at all. The price premium made a bad situation even worse.
As of 2021, the Power Stroke was $500 more expensive than the PowerBoost across the entire lineup, could not be paired with a 36-gallon extended range fuel tank, and was not available with Pro Power onboard – a mobile generator that became a real selling point after Texas’ 2021 winter storm crisis. In short, Ford was asking buyers to pay more for a truck that didn’t do anything better.
Common Problems with the 3.0L Power Stroke
Last, but certainly not least, the 3-litre Power Stroke suffered from problems which helped put the final nail in its coffin. The worst problem was the Bosch CP4.2 high-pressure fuel pump, which was not designed for the 520-plus-micron diesel fuel available in the US, causing metal-to-metal contact to become a problem, and causing small glitter-like metal shavings to find their way into the fuel system. Since it affected the rail, pump, injectors, valves, and fuel lines, the only solution was to replace them all – a task that could have cost $10,000.
The power stroke can also be affected by oil dilution during active regeneration cycles. Whenever fuel is injected into the cylinder, some of it may bypass the piston rings. When this happens, fuel can enter and mix with the oil in the pan, contaminating the oil, reducing its viscosity, and accelerating wear. So it became necessary to change the oil after 5,000 miles instead of the factory-recommended 10,000 miles.
Finally, the Power Stroke experiences problems with its diesel particulate filter and exhaust gas recirculation cooler, making it unsuitable for short distance trips. DPF clogging and EGR cooler failure were a recurring complaint throughout the engine’s production run. And not only was the Power Stroke struggling against its own in-house alternatives, but it was also outclassed by Chevy’s 3.0-liter Duramax – which launched in 2019 with 277 hp, 460 lb-ft, and a 33 mpg highway rating that outclassed the Power Stroke on every metric that matters.
