ATF can improve pump and injector longevity
Adding ATF to diesel fuel has been a topic of discussion and debate among diesel vehicle owners and enthusiasts. While some people argue that it can improve pump and injector longevity, there are also concerns and varying opinions about its effectiveness and potential risks. Here are some insights and perspectives on this topic:
ATF, or Automatic Transmission Fluid, has been considered by some individuals as a potential additive to diesel fuel. Proponents of this practice often highlight the potential benefits of ATF's high detergent properties. In theory, the detergent nature of ATF can help keep fuel pumps and injectors clean, reducing the buildup of deposits and extending their lifespan. This is especially appealing for older diesel engines that may encounter challenges with modern diesel fuel, which lacks the necessary lubricity.
One individual shared their experience, stating that they were advised by someone who rebuilds fuel pumps to add ATF to their diesel fuel. The recommended ratio was approximately 1 ounce of ATF for every 2 gallons of diesel fuel, translating to about a half-quart of ATF per fill. This individual also acknowledged the presence of strong friction enhancers in ATF, which could be a concern for some.
However, it's important to consider the potential drawbacks and risks associated with adding ATF to diesel fuel. Firstly, modern diesel injection pumps operate at much higher pressures and are made from different materials. Introducing ATF to these systems may cause more issues than it solves. While ATF can provide additional lubrication, there are specifically designed additives available that are more suitable for modern engines.
Additionally, ATF may not burn as efficiently as diesel fuel, potentially leading to a loss in power. This was observed by Richard Snyder, who experienced a decrease in power when running a 100% ATF mixture in his '02 7.3L Power Stroke. He typically uses a 90% ATF and 10% diesel mixture, which has not caused any issues in over 18,000 miles. However, common-rail fuel systems are more temperamental and may not handle ATF well.
Furthermore, ATF can increase pollution and produce harmful exhaust fumes, with visible smoke observed during idling. It's also important to note that ATF contains friction modifiers that can cause premature component wear and compromise the integrity of the fuel system. The formation of ash deposits is another potential concern.
While ATF may have been used successfully in older engines, modern diesel engines have different requirements and challenges. It is always advisable to consult with diesel experts and mechanics to determine the best additives and practices for your specific vehicle, especially with the availability of modern alternatives designed for today's engines.

ATF is a high detergent oil
Adding ATF to diesel fuel has been a topic of discussion and experimentation among diesel vehicle owners and enthusiasts. ATF, or Automatic Transmission Fluid, is a type of oil that is typically used in automatic transmissions. One of the key properties of ATF is that it is a high-detergent oil, which means it has strong cleaning abilities. This is why some people believe that adding ATF to their diesel fuel can help improve the longevity of their fuel pumps and injectors by keeping them clean.
The idea of using ATF as a fuel additive is not without merit. Its high-detergent properties can help remove deposits and buildup from fuel system components. This can be especially beneficial for older diesel engines that may have accumulated more carbon and varnish deposits over time. By cleaning these deposits, ATF can potentially improve fuel system performance and extend the lifespan of critical components like fuel pumps and injectors.
However, it's important to note that ATF is not specifically designed to be used as a fuel additive. While it may have positive effects on fuel system cleanliness, there are also potential drawbacks and risks associated with its use. One of the main concerns is that ATF contains friction modifiers and other additives that are beneficial for transmissions but may not be ideal for fuel systems. These additives can potentially cause premature component wear and compromise the integrity of the fuel system over time.
Additionally, ATF may leave ash deposits behind, which can build up in the fuel system and negatively impact performance. It's also worth considering that modern diesel injection pumps operate at much higher pressures and are made from different materials than older pumps. Using ATF as a fuel additive in these modern systems can cause more issues than it solves. While ATF may have been a popular choice for older diesel engines, it may not be the best option for modern diesel vehicles.
Today, there are specifically designed fuel additives available on the market that can provide the necessary lubrication and cleaning benefits without the potential drawbacks of ATF. These additives are formulated to work effectively with modern diesel engines and fuel systems, ensuring optimal performance and longevity. While ATF may have its place in certain applications, it's always recommended to use additives that are intended for their specific purpose to avoid any unforeseen issues.

ATF is a questionable alternative to diesel fuel
Adding ATF to diesel fuel is a questionable practice for several reasons. Firstly, while ATF is a high detergent oil that can improve pump and injector longevity, modern diesel injection pumps operate under much higher pressures and are made from different materials, so ATF may cause more problems than it solves.
Secondly, ATF doesn't burn as readily as diesel, which can result in a loss of power. Richard Snyder, who has been running ATF as his primary fuel for nearly two years, experienced this first-hand when running a 100% ATF mixture. He also has to regularly change his fuel filters and keep a spare with him at all times.
Thirdly, while there have been no reports of engine failures from burning filtered, used ATF as fuel, it is still considered risky as no mainstream testing has been conducted. Mechanics may be more inclined to take this chance as they have better access to used ATF, but older diesel owners may not want to take the same risk.
Additionally, ATF can increase pollution and harmful exhaust fumes, and there may be fines for using it due to some states checking fuel colour as a tax indicator. ATF also contains friction modifiers that can cause premature component wear and compromise the integrity of the fuel system, and it can leave behind ash deposits.
Finally, there are alternative additives that are better suited for modern motors and engines. For example, TCW-3 2-stroke oil is a cost-effective way to add lubricity to the fuel system, and it burns clean with no problems. Other alternatives include Marvel Mystery Oil, used motor oil, or kerosene, although the latter has low lubricity and can dilute the fuel.

ATF can cause premature component wear
Adding ATF to diesel fuel is a questionable practice. While some individuals claim that it improves pump and injector longevity, others argue that it can cause more problems than it solves. One of the potential issues with adding ATF to diesel fuel is that it can cause premature component wear.
ATF, or Automatic Transmission Fluid, is a high-detergent oil that contains friction modifiers as part of its additive package. These friction modifiers are beneficial for automatic transmissions, but when used as a fuel supplement in diesel engines, they can have negative effects. The friction modifiers in ATF can increase the friction within the engine, leading to increased wear and tear on the components. This can result in reduced performance, decreased fuel efficiency, and even potential engine damage over time.
In addition to causing increased friction, the additives in ATF can also leave behind ash deposits. These deposits can build up on engine components, further contributing to premature wear and reduced performance. The ash deposits can also impact the fuel system, compromising its integrity and leading to potential malfunctions.
Furthermore, ATF does not burn as readily as diesel fuel. This means that when added to diesel fuel, it can cause a loss in power and may even result in engine stalling. While some individuals claim that running a mixture of ATF and diesel has caused no issues, it is important to note that there has been limited mainstream testing on the use of ATF as a fuel additive. As such, adding ATF to diesel fuel is a risky practice that may cause more harm than good.
