WHAT IS BlueDEF™?

BlueDEF (Diesel Exhaust Fluid) helps a diesel-powered car or truck reduce emissions and improve fuel economy. BlueDEF is a mixture of 32.5% high purity synthetic urea and 67.5% deionized water that is used in Selective Catalytic Reduction (SCR) systems on diesel engines. DEF is the primary ingredient used to help convert NOx to harmless nitrogen and water.

BlueDEF is stable, colorless, non-flammable, non-toxic, and is classified as minimum risk for transportation. BlueDEF conforms to the ISO-22241-1 specification for DEF, is API registered and meets or exceeds OEM specifications.

BlueDEF Handling & Storage

The shelf life of DEF is directly related to the temperature at which it is stored. Storage temperatures between 12° and 90° F are recommended to maintain optimal shelf life of up to two years. If BlueDEF freezes, its efficacy will not be affected upon thawing.

To maintain the purity of DEF and not harm the SCR Catalyst System, care must be taken regarding the material of construction for all items that come in contact with the DEF solution. Included from the ISO-22241-1 standards are the recommended and not recommended materials for contact with DEF.
