Diesel Exhaust Fluid (DEF) is a 32.5 % solution of high-purity, synthetically manufactured urea in de-mineralized water. It is a safe-to-use fluid that is used in diesel engines with SCR systems to reduce emissions. Yara, a diesel exhaust fluid (DEF) producer, launched the first-ever DEF locator, which uses GPS technology to identify the DEF retail outlets closest to a driver's location. The DEF Filling Stations Locator, can be found online.
Originally available as an app, today it's available online. For fleets and drivers looking for a mobile app option, "DEF Pumps" by Inspirigence Works was available for download as of May 2023 via Google Play.
You can do a google search for "DEF Fluid Near Me," (or diesel exhaust fluid near me), or you can depend on the experts.
How to Find DEF Near Me
America's diesel-powered vehicles equipped with selective catalytic reduction (SCR) technology rely on DEF to meet the EPA's 2010 heavy-duty engine and vehicle emissions standards and to make sure their diesel engines run efficiently.
Consequently, easy access to high quality DEF, is essential for all drivers to ensure that their vehicles keep running and that the SCR technology in their engines remains in pristine condition. Drivers who download the Air1 DEF Mobile Locator app will now always know where the closest retail location to find the DEF filling stations whenever fleet drivers need to fill up or top off their tanks with high quality DEF.
"Currently, more than 35% of drivers own smart phones and approximately two thirds of those drivers are downloading apps," said Chad Dombroski, Yara's Director of Air1. "The Air1 DEF Mobile Locator was developed as a tool to help save drivers' time and make their lives a little easier by allowing them to quickly find out where they can refill their tanks with quality DEF while on the road.
As the first DEF app of its kind, the application allows operators to:
Find more than 600 retail outlets in the U.S. selling DEF near or along their route.
Search by city, state, or zip code for a DEF retail outlet.
Pick up a driver's location via GPS then calculate the distance and provide directions from their location to the nearest DEF retail outlet.
View the address and map location of various retail outlets selling DEF.
Yara has a number of supply relationships with petroleum marketers, oil distributors, gas stations, service stations, and truck stops across the United States and Canada that sell the company's Air1 brand of DEF.
Yara updates its diesel exhaust fluid (DEF) filling stations map each month. Check back often for updates and all of the diesel fuel updates!
