How to Determine the Quality of Diesel Exhaust Fluid


One of the factors that you have to explore even more than diesel exhaust fluid prices is the quality of the product you’re buying. Getting a great deal per gallon will end up being a problem in the long run if the quality is less than you’re expecting. There are several tests that diesel exhaust fluid goes through to make sure that the quality is where it should be at for your systems.

Determining the Quality

Diesel exhaust fluid has a standard set by ISO 22241-1 and other guidelines to ensure that you’re receiving the best quality possible. An open line of communication between you and your supplier is essential when it comes to determining the quality of your diesel exhaust fluid. You’ll want to inquire what analysis and testing are done on their products during the production process. You can ask if they are an API recommended Analytical Supplier which requires them to have the full amount of testing and analysis to qualify for the certification and licensing required by API. When corners are cut by testing and analysis not be completed, there’s a good chance that you may be rolling the dice when it comes to the quality you’re receiving.

Why Is Quality Important?

The selective catalytic reduction technology that works to reduce the oxides in the exhaust cannot handle impurities in the diesel exhaust fluid. Contaminants and other pollutants in a poor quality fluid can eventually cause it to malfunction or ultimately fail. This can lead to some big repair bills and other issues. Going through your due diligence to make sure that your supplier rigorously tests their product is the best way to ensure that you’re protecting your investment.

The Facts about Diesel Exhaust Fluid

In an effort to reduce emissions and promote healthier air quality, DEF is recommended for all diesel vehicles. DEF, or diesel exhaust fluid, is a non-toxic solution made up of urea and de-ionized water. When combined with the exhaust stream from a diesel vehicle, it breaks down emissions, transforming them into nitrogen and water. Without this valuable solution, the emissions produced by vehicles would increasingly compound, putting the atmosphere, and human life, at risk.

DEF was introduced as a marketable product in 2010. After the EPA standards were revised to reduce harmful pollutants, DEF was used as a way to reduce pollution while still promoting vehicle efficiency. While most car manufacturers have made adjustments to their engines in an effort to reduce diesel emissions, DEF can still help.
Most diesel-powered vehicles can benefit from DEF. If your vehicle was manufactured after 2014, there’s a good chance that it requires DEF in order to function properly. Trucks, industrial trucks, vans, and certain luxury cars should all be maintained with DEF to ensure efficiency.

Now, most diesel vehicles have a dedicated storage tank to hold DEF. Typically located next to the fuel tank; the nozzle for DEF is much smaller than the fuel tank, making it difficult to mix the two up. Simply refill the tank as needed to reduce your emissions and keep your engine running smoothly.

Many assume that DEF is a toxic substance that can cause major health issues when handled incorrectly. In all actuality, DEF is completely non-toxic, non-flammable, and non-hazardous. It’s safe for transport and poses no risk if it comes in contact with skin. While it may not be toxic, it’s extremely important to prevent contamination. Even a single teaspoon of salt could destroy the purity of 5,000 gallons of DEF. Take necessary measures to store and refill your DEF properly.

Qualities of a Good Exhaust Fluid Manufacturer


There are a few things that you consider when looking for a distributor of diesel exhaust fluid near me. You may review their location. You may evaluate their diesel exhaust fluid prices. Those are both excellent considerations, but you should also look at the distributor itself. Some qualities pinpoint which distributor is above the rest and deserve your business.


One of the first things to look for is accountability. You want a supplier that’s willing to admit that an error was made, and is ready to work with you on any problems that can come up.

Production Abilities

The next thing you should consider is the amount of production they’re able to tackle. Will they be able to fill your orders as you need them with the same high quality every order? A factory visit is often beneficial for this step.


As a global economy, there are often times when companies communicate through individuals that have different first native languages. Also, not every company has an open and direct line of communication. You want to find a distributor that you feel comfortable and confident in speaking with about your needs.

Quality Control

Is the company willing to have a third party check the product before shipping? Not every business is open to this step, but it’s an excellent way to ensure that the product your company receives is as it should be.

Ethical Sourcing

A final consideration is ethics. More companies are in the spotlight for violating moral boundaries, and this can result in boycotts and other serious ramifications. You want to be sure that the distributor that will be providing you with your diesel exhaust fluid will have the same high standards as your own company when it comes to how they do business.

The Importance of Calculating DEF Consumption


For those who operate a vehicle that runs on diesel, the integration of diesel engine fluid is critically important. With diesel exhaust fluid price per gallon at a manageable rate, there’s no reason not to use DEF. Not only does it reduce harmful emissions, but it helps your vehicle run in a cleaner, more efficient manner.

However, as is the case with all engine fluids, DEF should be accounted for so you know just how much you are using and, respectively, how much your engine is releasing into the environment. You can easily acquire this information with a DEF usage calculator.

Fuel Economy

For the benefit of your fuel economy, it’s recommended that your diesel exhaust fluid usage stay within bounds. Your fuel should contain around three percent DEF. Manufacturers suggest that you maintain this level by refilling your DEF every third time you refill your fuel tank.

Some long-haul delivery drivers have reported a 10 percent improvement in fuel economy while maintaining this level of DEF on their routes. Remember to use a DEF usage calculator to find out whether you’re using an appropriate amount of fluid. You can find a calculator by running a quick and easy online search.

Saving Money

When you enter your usage information into a DEF calculator, you may find that you’ve been using too much DEF. To overuse DEF is essentially to throw money out the window.

While the price of DEF is becoming more manageable (depending on your region), it’s still more than double the cost of diesel fuel on average. This could be because it’s become a rather hot commodity in recent years, especially with its positive environmental effects. Regardless of the reason, while the price is still relatively high, you’re going to want to monitor your usage.

Cold Weather Conundrum

A common problem for truck drivers is getting the recommended amount of DEF in the winter. Having outdoor DEF dispensers at truck stops can present a problem, as DEF freezing temperatures are similar to that of water (at 28 degrees it’s slush, at 11 degrees it’s ice).

One solution manufacturers have come up with to ensure trucks receive their necessary dose of DEF is keeping the fluid in insulated containers. These containers are free of contamination and keep the DEF pure and at an appropriate temperature.However, these containers may not always be available when you’re on the road. Therefore, your best bet is to calculate how much DEF you will need on your trip and to prepare in advance.

If you want to ensure you’re getting the best fuel economy available and you’re not wasting money, keep track of your DEF with a diesel exhaust fluid usage calculator. Happy driving!

Myths about Diesel Exhaust Fluid


Diesel exhaust fluid, also known as DEF, is a solution that is sprayed onto the exhaust stream of diesel vehicles to break down nitrogen oxides into much safer nitrogen and water. DEF is meant to improve air quality by reducing the pollutants in the air.


Here are a few myths about diesel exhaust fluid that you may not have heard before:

Only a Service Technician Can Refill Your DEF Fluid

This assumption is completely false. When making your purchase, the dealer may insist that this is true and that only a certified technician can refill the fluid for you, but that’s just an attempt to squeeze an extra dollar from you. Most automobiles have their fuel filler next to the diesel exhaust fluid, but a few are under the hood or in the trunk. The element that remains the same is, if you know where the DEF fluid needs to go, all it takes is pouring it in. You can do that yourself.

You Can Only Buy DEF Fluid at a Dealer

Salespeople often tell you this line as well, but it’s another false statement. They hype up the need to buy more fluid than you need to from them in order to stock up, but it’s just as accessible as any other automotive fluid at your location auto parts and equipment store. You can also find it online! It doesn’t take going through a dealer to get DEF fluid.

Avoiding a Dealer Voids Your Warranty

If someone sells you this line, don’t buy it. It’s illegal for a dealership to require you to purchase any oils, lubricants, or even DEF fluid strictly from them with the threat of voiding an associated warranty through them. So, not only do you not have to listen, but such a threat can give you grounds for legal action.

Non-Factory Fluid Hurts Overall Performance

This myth is just a way to steer consumers towards buying more expensive DEF fluid that isn’t essential. Don’t let these claims cause you to waste another dollar. Choose the fluids that are effective, affordable, and right for your vehicle, regardless of if the DEF manufacturers labeled their fluid factory or non-factory. The reviews for the type of fluid for your vehicle, and your own personal experience with your vehicle, won’t steer you wrong.

How to Choose the Right DEF Transfer Tank


Check Vehicles

To find the right diesel exhaust fluid transfer tanks, you should check how many and what kind of vehicles will be using the tanks. This will help calculate the right volume. Moreover, different vehicles have different specifications. If you are looking at buying for both tractors and trucks, make sure to separate the number of tractors from the number of trucks.

For Trucks

To find the annual number of miles, check the number of years and the number of miles that the truck drove. Once you have the number of years and the number of miles, divide the number of miles by the number of years. This will give you an estimate of how many miles the vehicle drives per year. For multiple vehicles, repeat the step, add up the annual miles driven for all vehicles, and divide by the number of trucks. The result will be the average annual number of miles.

Finding the average miles per gallon is the last step. To do this, keep track of how many gallons you use and how many miles you drive. Then, divide the number of miles by the number of gallons. The result will be the average number of miles per gallon. Repeat this step for every other vehicle, add the resulting number, and divide by the number of vehicles.

For Tractors

To find the average number of hours per tractor, find how many hours each vehicle was used. Then, take the total number of hours and divide it by the number of tractors. This will give you an estimate of the average hours per vehicle.

For fuel usage, find out how much fuel was used per hour. Like trucks, track how much fuel is used per work day. Take the number of gallons and divide it by the number of hours. The resulting number will be an estimate of how much fuel is used per hour.

Find the DEF Usage Rate

On average, engines consume 2-3% of DEF per gallon of diesel. For every 100 gallons, 2-3 gallons of DEF will be consumed. A high estimate of a DEF usage rate is 3% and a low estimate of a DEF usage rate is 2%.

Use a DEF Calculator

Having found all the appropriate numbers, input the resulting numbers into a DEF calculator. The result should be how many gallons of DEF were consumed that year. From there, you should be able to determine what diesel exhaust fluid storage tanks are right for your company.
