Why should I be careful of who I buy Diesel Exhaust Fluid from?

The ISO standard is set to prevent poor product being used, which ultimately may damage your SCR catalyst. These are irreplaceable and due to the nature of them they are very expensive to exchange.

This means licensed Diesel Exhaust Fluid suppliers, such as Air1, invest in production and distribution chains to ensure Diesel Exhaust Fluid is produced and delivered without compromise. However, there are suppliers of lower priced product who cut corners to save money, this may result in an inferior product which may poison your catalyst.
