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.
