Noxguard DEF is a high quality, API certified product, easy to find on truckstops and self-service stores

Diesel Exhaust Fluid (DEF) is not urine, as some might think.  NO organic, human or animal product is used in the elaboration of this chemical substance. The idea has been around for a long time since there is a lot of  ignorance on this topic. Although animals produce urine and a type of urea is generated in urine, DEF is not derived from human, cow or pig urine. In fact, Urea was the first natural substance that could be produced in a laboratory around the 19th century, and this is what is used for diesel engines that have SCR, part of the engineering that atomizes urea after combustion.

This urea is created in an industrial process and is a high purity chemical. As you can read on our website, DEF is made up of only two substances: 67.5% Deionized Water and 32.5% synthetic (non-animal) urea. Not even the agricultural urea is used to make DEF. Diesel engine manufacturers are very clear in the use of Urea specific for transportation that has an API certification (American Petroleum Institute), which can be verified on the product label.

Also, DEF is applied at the exit of combustion fumes in a dedicated tank with a blue cap, never mixing it with diesel. In order to save a few dollars, some users tend to believe advice given without really questioning what happens if you substitute a non-certified product for DEF. This will result in a huge bill for service and repairs to the unit, since this will damage the engine severely.
