DEF (Diesel Exhaust Fluids)

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 your DEF is free from harmful contaminants. Did you know that 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. To learn more, read our blog post on the importance of DEF cleanliness.

Simply Blue+ is available in bulk, totes, drums and jugs.

See 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!
