What You'll Learn
Additives vs. cleaners
While diesel fuel injector cleaners and additives are often met with scepticism, some people claim that they do work.
Additives are substances that are added to diesel fuel to improve its performance and/or clean the fuel system. Diesel fuel injector cleaners, on the other hand, are products that are used to clean the fuel injectors and may also provide other benefits such as improved combustion and ignition efficiency.
The main difference between additives and cleaners is that additives are typically added to the fuel tank, while cleaners are used to directly clean the injectors and may be applied in various ways depending on the product. For example, some injector cleaners are mixed with diesel and then poured into the main fuel line, while others are poured directly into the fuel tank.
Some people argue that additives are a waste of money, as they have not noticed any difference in power or mpg after using them. However, others claim that additives have helped improve their fuel economy and engine performance. For instance, one person shared their experience of using Power Service additive and not having any issues in ~500,000 miles over 3 trucks, while most of their colleagues who didn't use any additives had issues with poor performance and rough idle.
On the other hand, some people have found success with injector cleaners in improving their balance rates and freeing up sticky injectors. However, it's worth noting that injector cleaners may not work as a preventative measure and are more of a solution when issues arise.
In conclusion, while both additives and cleaners have their supporters and detractors, it seems that the effectiveness of these products may depend on various factors such as the specific product used, the type of diesel engine, and the frequency of use. As such, it may be worth trying out different options to see what works best for your specific situation, especially since some companies offer money-back guarantees for their products.

Do injector cleaners improve performance?
The effectiveness of fuel injector cleaners is a highly debated topic, with some people swearing by them and others believing they are a waste of money. While there is no definitive answer, there is evidence to suggest that injector cleaners can improve performance under certain circumstances.
One school of thought argues that modern common rail fuel injection systems are self-cleaning due to their operating pressures and tight tolerances, which keep the system clean without any additional additives. In addition, some people believe that injector cleaners are unnecessary unless there is a significant buildup or contamination, which is usually limited to the injector tips located inside the combustion chamber.
On the other hand, there are those who believe that injector cleaner additives are essential to maintaining good injector performance. They argue that while injector cleaners may not provide noticeable improvements in power or fuel economy, they can help prevent internal diesel injector deposits (IDIDs) and external diesel injector deposits (EDIDs), which can lead to premature failure of fuel system components.
Several products on the market claim to effectively clean diesel injectors and improve performance. For example, Hot Shot's Secret Diesel Extreme is a fuel additive that promises to improve fuel economy, increase horsepower, clean injectors, improve cold starts, and reduce black smoke.

How often should you use injector cleaners?
The frequency with which you should use injector cleaners depends on several factors, including the type of vehicle, the fuel quality, and the mileage. While some sources recommend using injector cleaners every 3,000 miles or with oil changes, others suggest doing it every 5,000 miles or even every 6,000 miles. Individuals who travel many miles or use low-quality fuel may require more frequent use of injector cleaners.
For example, Hot Shot's Secret Diesel Extreme, a premium 6-in-1 diesel additive, is recommended for use every 6,000 miles to deep clean injectors and fuel systems. It is designed to remove internal diesel injector deposits (IDIDs) and improve fuel economy and performance. On the other hand, a Reddit user mentions using Redline fuel treatment at every 5,000-mile oil change, while another user suggests doing it every other oil change, depending on the mileage.
It's worth noting that modern gasoline already contains detergents that help eliminate the need for injector cleaners. Additionally, some vehicles, such as the Duramax, may not show significant improvements even with the use of injector cleaners. In such cases, it might be more effective to use fresh, clean fuel or try alternative methods like hooking up a heavy trailer and maintaining high temperatures to burn off the carbon deposits.
The right cleaner and cleaning method depend on the specific fuel injection system and the severity of the carbon buildup. PEA-based cleaners are recommended for DFI engines, while alcohol-based solutions are better for removing moisture. Spray-on cleaners are also an option for selective cleaning.
