In this article, I will share real facts and experiences about the 6.4 Powerstroke engine so you can decide if it fits your needs and what to expect from it.
What is the 6.4 Powerstroke Engine?
The 6.4 Powerstroke is a diesel engine made by Ford, used mainly in their Super Duty trucks from 2008 to 2010. It is a V8 engine with 6.4 liters of size, built to give more power and better towing ability compared to older engines. Many truck owners chose this engine because it promised more strength and torque, helping with heavy jobs and long trips.
However, it is important to know that the 6.4 Powerstroke was also Ford’s first engine to use a special system called a diesel particulate filter (DPF). This system cleans harmful gases from the exhaust but sometimes causes problems if not maintained well. Also, the engine uses two turbochargers to boost power, which makes it more complex than simpler engines.
People who like the 6.4 Powerstroke say it offers solid power and a smooth ride. But some owners report issues with parts like the fuel injectors, turbochargers, and the DPF system, especially if the engine is not taken care of properly. So, knowing how this engine works and what to watch out for is very important.

- It uses twin turbochargers, making it complex.
- Many owners like the power, but some have had problems with parts.
How Does the 6.4 Powerstroke Perform in Real Life?
When it comes to performance, the 6.4 Powerstroke has some strong points and some challenges. Many truck owners say it delivers good power for towing heavy trailers or carrying large loads. It makes around 350 horsepower and over 650 pound-feet of torque, which is plenty for big jobs. The engine feels strong when accelerating and can handle tough conditions like steep hills or heavy hauling.
But the performance can change based on how well the engine is kept up. Because of the DPF system and the complicated turbochargers, this engine needs regular maintenance. For example, you must use the right diesel fuel and oil, and follow cleaning schedules to avoid clogging the filters. If you ignore these, the engine might lose power or burn more fuel.
Some people say the 6.4 Powerstroke is smoother and quieter than older diesel engines, which is nice for long drives. On the downside, it can be sensitive to bad fuel or rough driving habits. But if you treat it well, you will get strong, steady performance that works well for many tough jobs.

What Are the Common Problems of the 6.4 Powerstroke?
No engine is perfect, and the 6.4 Powerstroke has some problems you should know about before buying or using one. Many owners have reported issues that can be expensive or annoying. One common problem is the fuel injectors, which can fail and cause rough running or loss of power. Replacing injectors can cost a lot of money, so this is something to watch closely.
Another issue is the turbochargers. Since the 6.4 uses two turbos, if one fails, it can reduce the engine’s power and cause smoke or noise. The turbochargers can wear out faster if the engine is pushed too hard or if the oil is not changed regularly.
The diesel particulate filter (DPF) can also cause trouble. It traps tiny particles in the exhaust to keep the air clean, but over time it can get clogged. When that happens, the engine might go into a “limp mode,” meaning it lowers power to protect itself. Cleaning or replacing the DPF is costly and can be frustrating.
Other problems include the EGR (exhaust gas recirculation) valve clogging, electrical issues, and sometimes head gasket failures. Many of these problems come from poor maintenance or heavy use, but knowing about them helps you keep the engine healthy and avoid big repairs.
- Fuel injectors often fail and are expensive to replace.
