FALSE. There are many misconceptions about DEF in certain sectors, which brings us to the first assertion in this post: DEF is DEF regardless of the brand. Commercially, Diesel Exhaust Fluid is the same substance with the same ingredients since it is subject to a national regulation with the intention of protecting consumers. Specifically, bottled DEF brands must have the API certification printed in the label. This, in addition to being an indicator of quality, also requires manufacturers to put a batch number on said labels. Finally, the manufacturer must keep a physical sample of that batch, in order to identify any subsequent defects; there is an actual record of test tubes, and in the case of Noxguard, it can even be consulted by any buyer on our page.

DEF is DEF regardless of the brand

It´s not uncommon for CSR technology and indicators to fail, this is a reality that occurs more often than poor quality of DEF; of course, DEF must be adequately handled, avoiding contamination once acquired. There have been reports of consumers mixing DEF with diesel, which is a huge mistake, but some think: “it must be the poor quality of the product”. In any case, manufacturers provide a guarantee policy: a physical sample of the corresponding batch is compared with the DEF contained in the unit with a diesel engine. If there is a difference, contamination probably happened due to a bad handling of the product or adverse conditions when it was supplied and/or dispatched.
