Keep your engine running better while still protecting the environment.
Whether in vehicles large or small, on- or off-road, Blue Sky DEF is a trusted and environmentally responsible emission-control solution for diesel-powered engine operators everywhere.
As any operator knows, the purity of diesel exhaust fluid is essential for allowing engines and selective catalytic reduction (SCR) systems to operate at their peak performance, while at the same time reducing harmful pollution. Produced using deionized water and our proprietary reverse osmosis water purification system that exceeds stringent ISO 22241 and American Petroleum Institute standards, Blue Sky DEF prevents SCR breakdown, reduces harmful nitrogen oxide emissions by 90% and even improves fuel efficiency by up to 8%. In short, Blue Sky DEF makes your engines run better and helps you protect the environment, all while allowing you to keep more of your hard-earned money in your pocket.
Blue Sky is more than just a manufacturer of high-quality diesel exhaust fluid. We are the DEF experts. Our representatives work with you to develop customized DEF programs and strategies to meet your needs, regardless of whether you are in charge of a modest truck fleet, a large rail or marine business, a sprawling power generation station, or anything in between. With quantities ranging from bottle to bulk, we have the right solutions for you.

DEF is also available at our Corporate Office at 916 Adams St in Topeka KS; where we have 2.5 gallon drums, jugs, and totes available only during office hours of M-F 7a-5p.
DEF is also available for delivery.
If you’re not near one of the Cardlock locations listed above, we can also deliver sealed totes, barrels or 2 ½ gallon jugs of DEF to your location. Our bulk DEF system uses dedicated tanks, pumps and meters, all dispensed through a closed 1 micron filtered system. When you have a Micromatic connection on your storage tank, we can fill your onsite bulk DEF tank with the same product integrity of our closed 1 micron filtered system through a state certified meter.
