Diesel engines are known for their robustness and long lifespan, but like any engine, they require proper maintenance. A key part of diesel engine care is fuel treatment. Power Service Diesel Kleen, a widely recognized diesel fuel additive, claims to improve engine performance, increase fuel economy, and protect fuel systems from wear and tear. But does it really work? This article takes an in-depth look at Diesel Kleen to assess its effectiveness.
What is Power Service Diesel Kleen?
Power Service Diesel Kleen is a fuel additive designed to improve the efficiency and performance of diesel engines. It is primarily marketed for its ability to clean injectors, boost cetane ratings, and improve fuel economy. The product comes in two main varieties:
Diesel Kleen + Cetane Boost: This is the most common version of Diesel Kleen. It is used year-round to improve fuel combustion, increase engine power, and clean fuel injectors. It also provides a cetane boost, which improves the combustion process in diesel engines.
Diesel Fuel Supplement + Cetane Boost: This version is designed specifically for winter use. It contains an anti-gel component to prevent diesel fuel from gelling in cold temperatures.
Both products are part of a broader line of fuel treatments offered by Power Service Products, a Texas-based company with over 50 years of experience in diesel fuel additives.
How Does Diesel Kleen Work?
Diesel Kleen works by addressing several common issues faced by diesel engines. Diesel fuel injectors can become clogged over time, which leads to poor fuel combustion and reduced engine performance. Diesel Kleen’s cleaning agents remove carbon deposits from the injectors, allowing for a more efficient fuel burn.
The product also includes a cetane booster, which helps diesel fuel ignite more easily. Cetane is a measure of a fuel’s ignition quality, similar to the octane rating in gasoline. Higher cetane levels result in quicker, smoother combustion, reducing engine knock and improving overall performance.
Key Benefits of Power Service Diesel Kleen
The manufacturer of Diesel Kleen lists several key benefits of using the product regularly:
Cleans Dirty Fuel Injectors: Diesel injectors are prone to carbon buildup, which can disrupt the fuel spray pattern and lower combustion efficiency. Diesel Kleen helps restore injectors to their optimal performance, ensuring a more precise spray of fuel into the combustion chamber.
Improves Fuel Economy: By improving fuel combustion and cleaning injectors, Diesel Kleen can result in better fuel economy. When the engine burns fuel more efficiently, it uses less diesel to produce the same amount of power.
Increases Power and Performance: The cetane booster in Diesel Kleen improves the combustion process, resulting in increased horsepower and torque. Users may notice quicker acceleration and improved throttle response after using the product.
Prevents Wear and Tear on Fuel System Components: Diesel engines, especially those with high-pressure fuel injection systems, can suffer from excessive wear on injectors and fuel pumps. Diesel Kleen contains lubricating agents that reduce friction and wear on these critical components.
Reduces Emissions: Better combustion not only improves performance but also reduces the amount of unburned fuel that is expelled as exhaust. This leads to lower emissions of harmful pollutants like particulate matter and nitrogen oxides (NOx).
Does Diesel Kleen Really Improve Performance?
Many diesel owners have reported noticeable improvements in engine performance after using Diesel Kleen. These anecdotal reports suggest that the product can deliver on its promises of increased power and fuel economy. However, it’s important to consider that not every user may experience the same level of improvement.
Fuel Injector Cleaning
One of the main claims of Diesel Kleen is that it cleans dirty fuel injectors. Dirty injectors can cause incomplete combustion, reduced power, and poor fuel economy. Diesel Kleen contains detergents designed to remove these deposits and restore injector function.
There is scientific evidence supporting the use of detergent additives in diesel fuel. Studies have shown that these additives can effectively clean injector nozzles, improve spray patterns, and increase combustion efficiency. Therefore, it is likely that Diesel Kleen’s injector cleaning properties are beneficial, especially for older engines or engines that have been using poor-quality fuel.
Cetane Boosting
Another important function of Diesel Kleen is its ability to boost cetane levels. Diesel engines perform best with fuels that have a high cetane number, as this allows for more efficient combustion. Fuels with low cetane numbers can cause rough idling, hard starting, and increased exhaust emissions.
The cetane booster in Diesel Kleen can raise the cetane level of diesel fuel by up to 6 points, according to the manufacturer. This can make a noticeable difference in engine smoothness and power output, particularly in cold weather or when using lower-quality fuel.
Fuel Economy Improvements
Fuel economy is a major concern for diesel vehicle owners, especially those who rely on their vehicles for work or long-distance travel. Diesel Kleen claims to improve fuel economy by up to 8%. This improvement comes from a combination of cleaner injectors and more efficient combustion.
While there is no way to guarantee that every user will see a fuel economy improvement, many users report that their vehicles run more efficiently after using Diesel Kleen. However, it is important to note that fuel economy can be influenced by many factors, including driving habits, vehicle condition, and fuel quality. Therefore, the actual improvement in miles per gallon (MPG) may vary.
Long-Term Use and Preventive Maintenance
Regular use of Diesel Kleen can offer long-term benefits to diesel engines. By keeping fuel injectors clean and improving combustion efficiency, the product helps prevent the buildup of harmful deposits that can lead to costly repairs.
Preventive maintenance is critical for the longevity of diesel engines, and Diesel Kleen can be a valuable part of a diesel owner’s maintenance routine. The product not only enhances performance but also helps protect the fuel system from wear and tear, which can extend the life of fuel injectors, pumps, and other critical components.

Winter Protection
In addition to its performance-enhancing benefits, Diesel Kleen also offers protection against cold weather. Diesel fuel can gel in extremely low temperatures, making it difficult or impossible to start a diesel engine. The winter version of Diesel Kleen, Diesel Fuel Supplement + Cetane Boost, contains an anti-gel additive that prevents fuel from thickening in cold weather.
Using a fuel additive with anti-gel properties is essential for diesel vehicles operating in cold climates. Without this protection, diesel fuel can crystallize and clog fuel lines, leading to engine starting problems and potential damage to the fuel system.
Potential Drawbacks of Diesel Kleen
While Diesel Kleen offers many benefits, it is not without potential drawbacks. Some users have reported that they did not notice a significant improvement in fuel economy or performance after using the product. In some cases, this may be because their engines were already in good condition, with clean injectors and well-maintained fuel systems.
Additionally, Diesel Kleen is a fuel additive, not a miracle cure. It cannot fix mechanical issues such as faulty injectors, damaged fuel pumps, or worn-out engine components. Therefore, users should not expect Diesel Kleen to resolve major engine problems.
Is Diesel Kleen Worth the Cost?
One of the most common questions about Diesel Kleen is whether it is worth the cost. A bottle of Diesel Kleen typically costs between $10 and $20, depending on the size and where it is purchased. For most diesel owners, this is a relatively small investment compared to the cost of repairs or engine damage caused by poor fuel quality or neglected maintenance.
When used as part of a regular maintenance routine, Diesel Kleen can help protect the fuel system and improve engine performance. For drivers who rely on their diesel vehicles for heavy-duty work or long-distance travel, the potential benefits of increased fuel economy and power may easily outweigh the cost of the product.
