Depending on the composition of the fluid, mixing different DEF brands can affect the effectiveness of the fluid in some cases, as the mixture may contain either one or more of the active ingredients in the fluids at varying concentrations.
Also, some DEF fluid brands may contain additives or preservatives that are not designed to mingle with DEF from other brands, leading to corrosion or damage to your DEF system or engine. For these reasons, it is generally advisable to stick with one reputable brand of DEF fluid and not mix different brands.
Does DEF quality Matter?
Yes, DEF quality does matter. Diesel exhaust fluid (DEF) is a solution used in select diesel vehicles to reduce emissions of nitrogen oxides (NOx) from a vehicle’s exhaust system. It is a required component of the Selective Catalytic Reduction (SCR) system and must meet stringent purity requirements.
Good quality DEF is essential for SCR to function properly and reduce emissions.
Low quality DEF can contain impurities that can damage the SCR system, resulting in increased emissions as well as costly repairs. Impurities can also cause crystallization within the SCR system if left untreated.
This can further damage the SCR system and lead to decreased vehicle performance and fuel efficiency.
Overall, the use of DEF allows diesel vehicles to meet strict emissions standards. If DEF is of poor quality, then the full benefits of the SCR system are not realized, leaving vehicle owners out of compliance with emissions standards.
This can lead to costly fines and penalties, as well as decreased performance of the vehicle. For this reason, it is important to use good quality DEF when refilling your vehicle’s DEF tank.
What happens if you use bad DEF?
If you use bad diesel exhaust fluid (DEF) in your engine, it can result in a number of problems, including reduced engine performance, exhaust emissions that fail to meet required standards, and potentially costly repairs.
Poor-quality DEF contaminated with water, oil, and other impurities can contaminate the diesel particulate filter (DPF) in your vehicle and lead to a significant buildup of particulates, blocking the exhaust system and the catalytic converter.
This can cause a significant drop in engine performance, an increase in fuel consumption, and an increase in exhaust emissions. Additionally, the contaminated DEF can reduce the efficiency of the DPF, causing increased backpressure in the exhaust system and further reducing engine performance.
In some cases, the DPF may need to be replaced, which can be costly. If this happens, it is important to use only the highest quality DEF to ensure the best engine performance and reduced emissions.
Why does my truck say poor DEF quality?
Poor DEF (diesel exhaust fluid) quality indicates that your truck’s DEF system has detected a problem with the quality of the fluid in the tank. DEF works to clean the exhaust gases produced by your diesel engine, and if the DEF quality is poor, it’s not able to effectively reduce pollutants from the exhaust.
Poor DEF quality can have a variety of causes, including: a failed DEF pump, a clogged DEF line, air entering the system, contaminated DEF fluid, a DEF dosing unit malfunction, or a failed exhaust temperature sensor.
Each of these problems can cause issues with the DEF fluid’s quality and reduce its ability to clean the exhaust gases. If you believe your truck is displaying the “poor DEF quality” message, it’s important to have it diagnosed by a professional as soon as possible.
Repairing the problem is often much cheaper than replacing the entire DEF system, so it’s important to identify and remedy the issues as soon as possible.
What should my DEF quality be?
The quality of your DEF should depend on the quality of the diesel fuel and the systems that are using it. Generally speaking, DEF should be of a high-quality as it affects the performance of the diesel engine and its exhaust systems.
Higher quality DEF can reduce or eliminate problems like excessive smoke, clogged filter systems, and decreased fuel economy. The only way to definitively determine the quality of your DEF is to have it tested by a qualified laboratory.
In most cases, DEF should meet the standards of ISO 22241 and be free from contaminants like water, ethanol, petroleum, and nitrate. Depending on the complexity of your diesel engine and its emission systems, you may need a higher-quality DEF than what is required by the standards.
What is a good DEF quality percentage?
A good DEF quality percentage depends on a variety of factors including the use of the vehicle, the durability of the DEF, and the engine’s emissions system. Generally, a DEF quality percentage below 25 percent may cause the vehicle’s emissions system to malfunction, while percentages over 75 percent are considered optimal.
It is important to note that the quality of DEF may degrade over time and vary between brands. Therefore, it is usually recommended to use a fresh batch of DEF, which has a quality percentage of approximately 85 to 90 percent, for optimal performance.
The DEF quality can be monitored using an infrared spectrometer which is designed to measure the DEF concentration levels. Additionally, for applications subject to higher levels of stress (high speed or hauling heavy loads) higher quality of DEF is often used, ranging from 90 to 95 percent.
Therefore, an appropriate DEF quality percentage for any given situation will ultimately depend on the type of engine and the application in use.

Still, since DEF can help diesel vehicles and machinery comply with emissions standards, it is an essential ingredient in maintaining the health of our environment and because of this, any signs of a potential shortage should be taken seriously.
The best advice at this time is to stay updated on the current events relating to this potential shortage, and to prepare accordingly in case DEF shortages occur in the near future.
Is there a shortage of DEF for diesel engines?
Yes, there is currently a global shortage of DEF (Diesel Exhaust Fluid) for diesel engines. This shortage is largely due to increased demand caused by the rise in popularity of diesel vehicles and the use of diesel-powered vehicles in many commercial settings, such as the transportation industry.
The combination of these factors has created a strain on the supply of DEF and has resulted in shortages in many areas.
The shortage of DEF is further exacerbated by the fact that it is not a widely produced item. DEF is made in only a few locations and transported to a variety of locations throughout the world. Because of this, it can be difficult to maintain a steady supply as long distances and unreliable transportation can often result in shortages.
Fortunately, the shortage of DEF appears to be a temporary issue and should be resolved with increased production or additional transportation of DEF in the near future. It is important that drivers of diesel vehicles take special care to ensure that their vehicles are properly maintained and that they are not using DEF from unreliable sources.
By doing so, they can help reduce the effects of the current shortage.
What happens if there is a DEF shortage?
If there is a shortage of Diesel Exhaust Fluid (DEF), it will have an effect on the operation of many diesel-powered vehicles, particularly those fitted with a Selective Catalytic Reduction (SCR) system.
Without adequate DEF, the SCR system cannot fully reduce its NOx emissions, causing the vehicle to run less efficiently and potentially even fail an emissions test. Furthermore, diesel engines that do not have an adequate supply of DEF may have a shortened lifespan as the harmful by-products of exhaust are not fully removed.
In order to avoid a DEF shortage, it is important that owners of diesel-powered vehicles ensure that their vehicles are regularly serviced and topped up with DEF when necessary. Alternatively, it is possible to purchase bulk DEF and store it onsite, allowing vehicle owners to proactively respond to a shortage of DEF on the market.
Regardless of the strategy employed, implementing some form of proactive DEF management will help to prevent costly downtime and extend the life of the vehicle.
