Diesel Exhaust Fluids (DEF)

Allied carries Simply Blue+ DEF, an API-certified, ultra-pure, formaldehyde-free DEF.

All Allied locations have been certified by CF Industries in the proper handling and packaging of bulk Simply Blue+ Diesel Exhaust Fluid, so you can trust that your DEF is free of harmful contaminants. Less than a teaspoon of materials such as copper, zinc, iron and aluminum can contaminate your DEF. This can result in a number of issues from shorter product shelf life to replacing your catalytic converter.

DEF fluid breaks down nitrogen oxide emissions into nitrogen and oxygen. It is important to remember that DEF is not a fuel additive and should not come into contact with diesel as they are stored in separate tanks.

Simply Blue+ is available in bulk, totes, drums and jugs. Read our blog about DEF.

Your tour guides did an excellent job of explaining all the processes involved in detail. They also answered all the numerous questions we had.

Each and every day, I am so glad I chose Allied for tires and oil.  The Des Moines (Iowa) crew is fantastic and I feel like I am in the “safe zone” every time I pull in there.  And choosing the oil was just one more good move I made.

I am very satisfied with what ESCO did for the district. They worked well together as well as being very clean. They understood the busy area. I would have them work on anything in the district. Great job guys!
