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.

Driving Consciously: How DEF Helps Reduce Vehicle Emissions

Fueling up Driving on diesel fuel has undeniable benefits. With diesel’s low price per gallon, driving a vehicle that utilizes this type of fuel can seriously pad your wallet. However, did you know that due to the cool temperature that a diesel engine runs at, you may be emitting harmful gases when you drive? This is the result of your catalytic converter, which works to purify harmful gasses, not working as effectively as it would in a hot, gasoline-powered engine.
But don’t throw in the towel on diesel fuel just yet. Regularly using diesel exhaust fluid (DEF) can amend this issue. Furthermore, due to EPA regulations, diesel exhaust fluid prices per gallon are currently at a low and manageable rate from distributors.
Still, you may be wondering, what does DEF actually do? Is it even necessary to spend the money on it? Read on to discover how DEF works and the numerous benefits of using it.

How Does DEF Work?

Since a typical catalytic converter is ineffective in reducing diesel fuel emissions, diesel engines are equipped with a selective catalytic converter. This kind of catalytic converter helps to reduce specific harmful emissions such as nitrogen oxide, and it succeeds.
DEF is essential to this process. The chemical urea in DEF reacts with the nitrogen oxide after it has left the engine, turning 90 percent of it into nitrogen and water vapor. This almost completely eliminates the harmful emissions in your vehicle’s exhaust.

What Are the Benefits?

The gasses that are eliminated from your vehicle’s exhaust are harmful to both the environment and human beings. Nitrogen oxide emissions have been observed to correlate with conditions such as asthma and heart disease. DEF also contributes to reducing air pollution.
All of that aside, do you really want embarrassing and stinky black smog flowing from your tailpipe?

Caring for Your Vehicle and Wallet

You may still be concerned about diesel exhaust fluid prices as well as what you’re putting into your car or truck.
You want to make sure when you’re spending money on DEF that you’re putting a quality product into your car. Blue Sky is one of the many companies that works to ensure diesel exhaust fluid quality at a manageable price so you can not only help the environment, but you can also know that you’re putting a tried and tested product into your vehicle.

The Advantages of Using Diesel Exhaust Fluid

Diesel Exhaust Pipe

In 2010, the EPA changed the emissions standards for three-quarter and one-ton trucks to make them more stringent. Because of this, truck manufacturers were forced to start coming up with new ways to reduce emissions without compromising the power of their vehicles. Nearly all manufacturers turned to a selective catalytic reduction (SCR) system to comply with the regulations, most of which use diesel exhaust fluid as a key component. Luckily, diesel exhaust fluid suppliers can be found just about anywhere from truck stops to retail chains like Walmart, so it’s readily available wherever you’re out on the road.

5 Facts about Diesel Exhaust Fluid

In 2010, the EPA revised standards to lower NOx levels in new trucks in order to help reduce pollution to the environment and improve cleaner diesel emissions. Many original equipment trucking fleet manufacturers started using (SCR) catalytic reduction technology to lower NOx emissions and also increase fuel economy as well as reliability without the need to change operation or essential design of the standard engine.

The Importance of Calculating DEF Consumption


Many truck operators have engines with exhausts with selective catalytic reduction after-treatment systems and have claimed their fuel use is as good or close to what the manufacturers claim. You must also factor in the diesel exhaust fluid that’s used in the process. Injecting DEF into your exhaust helps to neutralize nitrogen and oxides, or better known as NOx. This is the action from the SCR which is used by many diesel manufacturers. DEF, much like fuel, is used every day, and for all intents and purposes, should be accounted for in claims or economic reports. Your best bet is using a DEF usage calculator.

DEF Consumption

The thing to figure out is how much DEF are you using. Manufacturers using SCR in over road operations suggest a rate of around 3%, which roughly equals out to about 3 gallons for every 100 gallons of fuel. Some long-haul carriers have seen a 10% improvement in fuel consumption when running identical routes. This is comparing SCR units to older models. There have also been some disappointing reports, claiming poorer fuel economy. The expert opinion is that performance comes down to factors such as road, route, and service. It’s recommended that drivers refill DEF at least once in every third time they refill their tanks.

Climate Consideration

One of the challenges facing truck stops is what to do in colder climates. Having a DEF dispenser in an area with low temperatures is an issue because DEF becomes slush at 28 degrees and will freeze at 11 degrees. This is a factor that must be considered in your overall DEF use, depending on your route. However, there are storage solutions available for both large and small-scale fleets, commercial locations, and retail facilities. Insulated bulk storage containers can help install contaminant-free DEF in extreme weather conditions. The containers ensure the approximate shelf life of DEF does not get hindered.


With the cost of DEF slowly coming down from where it was when it first hit the market, it’s also becoming more attractive. This doesn’t mean that DEF’s price isn’t all over the place, depending on your geographic area and retailer. When and if DEF becomes the same price as diesel fuel, the urea injection economics will merely be about subtracting DEF cost from the truck’s fuel improvement.
